content: Meeting pointto organize group buy of precision resistor sets forLTZ1000 circuit.Mainly for 10V pcb (branadic / Dr. Frank), but not limited to that.I think group buy would only make sense when a couple of people want small quantity of same type (to save shipping cost and get volume cut in price - hopefully).I am not familiar with precision resistors, so I do not really know where to go:- Vishay Z/VH/VHP and equivalent as dividers (incredible long lead time?)- Edwin G. Pettis Ultrohm Plus (seem to have a good price point) -specs,thermal shock resistance- Rhopoint Econistors- ?[modified quote from pm]Quote from: Edwin G. Pettis on October 01, 2018, 08:14:39 pm

content: I would be interested in any of those. I have already contacted Edwin about some sets in addition to some other special resistors I need but I've struggled to figure out how to get a set of Vishay metal foils. Can't seem to find an economical or easy way to get them from Australia.

content: I vote for Edwin's resistors.Have measured many s102k vishay resistors and most are not "typical" they have more tempco than expected. The VHP series are WAY pricey and have those very long lead times.For other off-the-shelf I have good experience with Susumu RG series 2ppm, they all were close to spec. These are only available in SMD style so would either need another pcb or an adapter. Plus it would be a custom order for the non-traditional values.So, in my limited experience, Edwin is the best bet.

content: Quote from: RandallMcRee on September 24, 2018, 02:58:30 pmIf you are in the USA then there is no need for a group buy. I think MiDi is based in Germany, the EU - so every single shipment of a handful of Edwins resistors are subjected to extreme "Let me see your paperz" at the Merkel border, potentially held up for months, then finally released having had massive surcharges, duties and taxes stamped on them.A group buy with a destination outside of Herr Merkels border zone, like Switzerland, could be advantageous when EU cross border shipping no longer attracts the UK HMRC or German Customs Gestapo.But I think MiDi is based in Germany and so is really the worst EU member to arrange such a transaction. Even Dave refused to ship his DMM's to Germany.For some reason we don't have this with stuff imported from China. As a Brit I look forward to Brexit so we can drop this insane EU shit and import stuff as freely from the USA as we get with China.

content: Right, in for a penny, in for a pound. I've just ordered 3 sets of Ultrohm Plus PWW, 2 sets of SFERNICE foils from E-bay and a set of 3 KX boards from OSHPark to go with the boards branadic is producing. If I'm building one, I might as well build 5 or 6 right?The SFERNICE foils are not particularly an optimum set with the values being : 123R / 965R / 12K4 / 68K1 so the set temp will be somewhere around that provided by a 12K85/1K divider. They are also only 5ppm, so we'll see. A start to experiment with anyway. They were about $40 / set. The PWW were about $65 a set including shipping (our exchange rate is horrid right now) but at least they're the right values and reputedly far more stable.I wouldn't mind spending some real money on a (single) set of hermetic Vishays including a 12.5K/1K divider if someone was going to organise a group buy though.The LTZ1000ACH at Digikey is backordered until November, so I'll be waiting a while until those land. So far I've put a few bucks over the counter, so there's some incentive to make this more than a pile of parts sitting in a box in the corner

content: Since I've shipped into a number of EU countries.....on the whole, yes the German customs tends to be the most difficult to get packages through, it also depends to some degree on which customs in which city it goes through, some are much more difficult than others. I'm told there are fees on top of fees and the ever present VAT. The dollar value for no significant fees is about $20, that is meant to make sure very little comes into the EU without being nailed and makes it more difficult to fudge on the value a lot. They are also very suspicious of too many samples or of what looks like very low pricing, that may or may not trigger a customs battle. I do not know of any customs free duty on PWW resistors in any EU country, if there is none of my customers has mentioned it. You might be able to get away with shaving some of the actual costs off of the customs paperwork for reduced fees/taxes but it can't be excessive.Each country tends to be different in how they handle customs, there doesn't appear to be any universal rules being applied outside of perhaps the VAT. I would presume once the resistors are 'inside' the EU, there would be no further problems/charges/fees on distributing them to other countries outside of postage. It would only be a matter of checking around with EEVblog members to find the lowest cost entry country.I also give pretty good quantity discounts......end of ad.

content: Quote from: Edwin G. Pettis on September 30, 2018, 07:26:43 pmHello,but shurely not by the customs.Maybe if you send it by a parcel service they call for a handling fee for the customs.The normal customs process (sending by USPS/Deutsche Post) up to 2kg in a jiffy bag is relative easy.The package after import goes directly to the local customs store.After around one week you get a letter that you have to pick up your package at the local customs.You should have the "Zolltarifnummer" (TARIC) or HTSUS number at hand so that they can calculate correctly the duty rate(which is 0% for resistors below 20W at the moment).http://ec.europa.eu/taxation_customs/dds2/taric/measures.jsp?Lang=de&SimDate=20181001&Area=US&MeasType=&StartPub=&EndPub=&MeasText=&GoodsText=&op=&Taric=8533210000&search_text=goods&textSearch=&LangDescr=de&OrderNum=&Regulation=&measStartDat=&measEndDat=HTSUS: 8533.21.0080Description: Electrical fixed resistors, other than composition or film type carbon resistors, for a power handling capacity not exceeding 20 WMFN Duty Rate: FreeOf course you have to pay the VAT (Einfuhrumsatzsteuer) which is 19% at the moment in Germany. (So mostly lower than in other european countries).So you need a invoice and the paypal/paying receipt.And there is a speciality if you import: Customs has a own (monthly fixed) exchange rate when importing things so the 19% are not exact 19%(ok this may appear as fee on top of a fee).http://www.zoll.de/SiteGlobals/Forms/KursSuche/KurseSuche_Formular_Initial.html;jsessionid=1D3765BD6DA32B62D74B2C5DE084508B.live4411?nn=298534Disclaimer:Above are experiences on 2 small orders of around 5 LTZ (7V) resistor sets each.If ordering large quantities it might be necessary to have a customs EORI-number.With best regardsAndreas

content: !2k is cutting it a bit close unless you are in a cooler controlled environment such as a lab at 23°C-25°C or located in a cooler country. I do not recommend using less than 12.5K as a minimum and I regularly recommend 13K as the universal value to assure correct operation of the LTZ. Remember the LTZ is a power in, power out device and the real temperature you need to pay attention to is the internal temperature of the LTZ, that is where the regulation of temperature occurs, it is not the same temperature as the environment. You are not really gaining anything in long term stability by trying to shave off a few degrees. HP/Keysight uses 15K in their modules and that includes the 'golden' 3458As and they are perfectly stable for years at that temperature. You definitely do not need to run it with 15K, unless you're running it in a rack for instance, but you aren't going to get better stability by running it too cool either.

content: Thank you for clearing up what that HTSUS number does, I do indeed include that on the customs when I ship to Germany and Andreas was the one who originally supplied it to me, thank you. Since I am not on the 'receiving' end, I can only go by what my customers have told me about their customs experience, in Germany it has varied some depending on where the package went, some local customs were exceedingly picky about paperwork and contents while others not so much.

content: I ended up going for ±0.1%, ±3 PPM/°C for everything except the output divider which is ±0.01% mostly for vanity sake.I was tempted to get lower tempco R4/5 resistors, but tbh I'm too newbish with voltnutting for that to be worthwhile. Once I can measure the end tempco of the whole reference then maybe I'll upgrade them. Or try to match the three sets I have as close as possible... Sounds like a great way to never actually build the whole circuit.Thanks MiDi for organizing this buy, it's pushed me to actually go forward with it!

content: Quote from: pansku on October 15, 2018, 10:39:52 amI haven't ordered any boost resistors. I've gone with 4 standard LTZ sets. 3 with 13k and 1 with 12.5k. Reading Edwins posts he specs his resistors at 3ppm as that appears to be the worst possible case (short of damage). If you wanted anything specifically tighter I suspect then you're into testing and selection and that might get expensive, although prices I've seen bandied about even for unrealistically tight tolerances seem to be pretty damn reasonable. I plan on testing 4 sets to figure out which parts track the best for a single "best" set with the 12.5k resistor. It feels a bit like bike-shedding, but what they hey.Anyway, some Sfernice resistors arrived today so when the boards get here I have 2 I can assemble while I wait for the Ultrohm Plus units to arrive (I ordered mine a couple of weeks ago, before the *special* offer so hopefully I'm ahead on the production queue). I have KX boards due in the next day or so, and the boards from branadic should be here in the next couple of weeks.

content: I've had an inquiry about the final pricing, so to hopefully prevent a bunch of e-mails:After I announced the base price and discount, the orders kept coming in, necessitating a restocking of some inventory. I have been running on inventory I bought awhile back, since then the supplier has raised prices significantly (over 100%). Since I didn’t want to hit a significant number of later ‘Halloween’ customers with a large increase, I took a minimal amount averaged into all of the parts which did bring the discount down a little, without it; it would have been closer to 9% or less. I had not increased my pricing while I was running off of the old inventory knowing that someday I would have to restock and get stung by the higher prices. There is no way around it. Once this ‘NOS’ inventory is gone I will have to bump up prices to cover the increase and I won’t be able to soften the hit like I did now. The pricing is still at the 100+ price discount even with the small hike. According to my research, my pricing is still lower than Rhopoint’s or NEOHM's 100 piece pricing.

Once we're out of the club, we'll have to deal with Germany the way the USA etc. does now - painfully. The USA will probably be the same as it is for us now, unless Trump throws a wobbly. So will the middle east, because the arms dealers don't want to pay too much tax. China should be the same, but one day HMRC will catch up with them and start taxing them to the rules. So .. I'm not sure where will be easier to deal with. Somewhere that isn't the far east, the far west, europe. And does electronics. Maybe Putinland ?

I have started production on orders from the 14th. Some orders contained additional resistors over and above the LTZ and scaling resistor sets which took additional production time. The same can be said for the remaining orders, a few are fairly large. I am notifying everyone as I get near or start production of your order. Be assured I am making them as quickly as is possible.

content: To all the remaining orders from the Halloween discount......I had to order more bobbins last month (May) as I was running out of inventory, I was just notified of a problem at the manufacturer that will delay shipping a few more days but should be very soon, they are being shipped air mail. Sorry for the delay but the mix up made the bobbins unusable in their current state and they required additional machining to fix the problem. I will notify the remaining customers when their orders go into production. Not what I wanted but it happens, the remaining orders are mostly smaller ones so I should be able to get through them relatively quick.
