But not for long.A cap on the input vented out through the potting compound - It's rated at 35V- Thats one problem, another one is the cap on the 24V output is rated for 25VI have contacted the seller, now waiting for a solution.EDIT: The seller has already responded, and agrees to give me a refund.So, can you guys advise a product similar to the other, that will not blow up? I don't care if the price is higher, it's just hard to find a 48V (60V) to 24V DC-DC inverter.

timestamp: December 10, 2016, 09:23:09 pm
content: It depends on the manufacturer, but it is related to the lifetime of the cap, if you keep the voltage lower than the rating it lasts very long, then it winds up in kind of an exponential decay as you get closer to the rated voltage, and past that it adds on a second exponential term and starts falling to zero pretty quickly from there on.
How Long Have Your Cheap "Hakklone" Soldering Tips Lasted? - Page 1

content: Because my favorite tip, the giant chisel tip (don't know the correct name) has been used for over a year now, sometimes on rather high temps (>450 degrees) and even occasional plastic melting, which I'm well aware is not good for them.Anyway, after wrapping the heater in foil for better themal transfer, this iron is astounding, at 450 degrees it can solder onto 1.5mm sheet metal.Here is the condition of mine after a year, and yes, I'm aware that my camera's focusing mechanism has ADHD, like me.I'm not sure about you, but for an insanely cheap tip (it came with the station) to last a year through some rather abusive soldering sessions, I'm very impressed. Dave has said that the cheap stuff isn't worth dealing with, but I honestly have to disagree.

The window title for a lot of electronics will be randomly changed to another item like "Cool Men Skateboard Shoes Galaxy Lace Up Skate Running Sports Walking Shoes Men", which I've never searched for or looked at, just 100% random. These sorts of problems are more common since the Donahoe era; I think they are cutting costs by firing all their DBAs.

timestamp: December 10, 2016, 05:52:57 pm
content: Yes, power is the time rate of change of energy. Two simple examples:When you charge a capacitor, you increase the energy contained in the unit. When you discharge the capacitor through a resistor, the power dissipated in the resistance reduces the energy in the capacitor.The chemical energy contained in your gasoline tank is burned in the automobile engine to produce the power that accelerates the car, while draining gasoline out of the tank.

content: Energy and power are related in exactly the same way that distance and speed are related. In calculus terms, one is the integral of the other over time.If you maintain a certain speed for a certain time, you will travel a distance that is the rate times the time. For example, 10 meters/second for 20 seconds will take you 200 meters.Likewise, if you maintain a certain power level for a certain time, you will deliver or consume energy equal to the power times the time. For example, 10 Watts (a Watt is a Joule/second) for 20 seconds is 200 Joules.Power is the speed of energy transfer.

Anyone recommend a supplier of cut/stripped wire in the USA? - Page 1

content: As the title says, looking for a supplier of cut/stripped wire. Immediate need is 10" long, UL1061 hookup wire, 22/7 stranded, 0.1" tin and strip on one end, 0.1" semi-strip on the other end. I need them in black, red, orange and yellow, roughly 2500pcs of each color, and it's a recurring order.I was buying these from Squires Electronics in Oregon for years, but they were bought by Kauffman Engineering and despite saying they would quote me, they haven't sent a quote despite numerous calls and promises to do so. It seems they aren't interested in my business - which is fine - perhaps they are pursuing other types of work, no problem.It seems this is pretty simple work for someone with a wire processing machine. I know it's not a huge job, but we occasionally need things like this as well as other types of wires and cable assemblies like a connector with bare wires on the other end. I likely have a need coming up for 3mm vinyl sleeved bullet connectors crimped onto 6 inch long 18ga-wires for example. So ideally, a supplier who does connectors, terminals and cables would be ideal... but right now I just need the cut/stripped wires.Any recommendations?

Better for a night out in the boozer is to turn off all the social messaging apps instead, and use the phone only as a device for talking on.I know, strange to actually use it as a thing to talk on, but a lot better than pulling a Penny Sparrow.Or consider turning it off, or just using a feature phone instead. Still gives the warm fuzzy feel of having the fondleslab, but only can do drunken calls, not do something that will land you in prison for a decade and make your life thereafter a living hell.

content: Are you checking the correct pins? The DB-9 hasRequest To Sendas pin 7 andClear To Sendas pin 8. Are you using an oscilloscope? RTS is the signal you can control. CTS is a response, say from a modem, but you can loop the two for testing, where if you assert RTS, CTS should go high. I do not recall a software setting to disable these.Try Terminal by Bray. I have not used RealTerm in about 4 years, but turn on hardware flow control if it is an option. I had a Dell 800 and the monitor went bung (a common problem) shortly after the warranty ran out. You are lucky yours is still going.

Later that weekend (the Black Friday sale went until midnight Sunday) I attempted to use the SAVE7 code to buy a Rigol oscilloscope after 9 pm Pacific Time on Sunday, only to get an error message telling me that the SAVE7 code was invalid.The following day a TEquipment customer service rep confirmed to me that the midnight expiration time for discount codes they provide is effective midnight their time, which is USA Eastern time... which is 9 pm my Pacific time.I didn't buy that Rigol oscilloscope.

content: The idea is not that new. It is done for at least 20 years - though the ones shown might be smaller than the ones I know. One initial idea was to use them as high Q filters - however this is today in many parts replaced by digital signal processing. Another use might be relatively stable (high Q) resonators - however to get a high Q and thus be a real alternative to a crystal, one would need vacuum.I have used similar (though larger) micro-mechanical resonators at the university. In vacuum they can get a really high Q - in som cases comparable to crystals. I have measured values up to 1E6. However there is a higher temperature drift. I could imagine a few niche applications as a high Q tunable resonator and maybe as sensor. I build the right way and for the smaller high frequency ones, they are nor that sensitive to external vibrations - for the shown version it is more the measurement system that needs vibration insulation, not that resonator itself.

content: There are "silicon oscillators" that claim to be MEMS, though it's unclear what structures they use (and how they're temperature compensated). They are usually programmable, which seems to suggest there's a PLL and P/Q divider or DDS to generate the output.Certainly, this approach gives better universality to an otherwise fairly fixed and narrow design (i.e., you can only make the MEMS elements so large before they're impractical, or so small before they're unusable). They get better ROI, if not necessarily better performance as a result (if the PLL suffers from phase noise outside of the loop bandwidth, or if the DDS suffers from excess jitter). That said, they're usually comparable to, or better than, cheap crystal oscillators.I don't see MEMS filters offhand, though SAW could arguably be called a similar technology. Mechanical filters (made from, I think, nickel or terfenol as transducer, and various mechanical resonator bits) had been common back in the day.Tim
LDMOS and destruction avoidance - Page 1

content: I am putting together an RF amplifier - there is an LDMOS driver and then a pair of final 75W LDMOS transistors, 120W at 1.3GHz. The problem I have is LDMOS is very sensitive to overdrive, but its also not that linear and under fault conditions the driver could destructively over-drive the finals. I only need 10W from the driver, which is where it is fairly linear, but it can produce over 40W at saturation. I want to hard limit the maximum power the driver can deliver. I could reduce the drain voltage but this just makes it less linear. I was wondering if current limiting might be better. I could use a RF output monitor trip but that's a lot more complicated and might not be fast enough.I am not worried about over-driving the driver, its much more robust to over-drive than the final transistors.Mike

Again the issue is speed, but maybe you can design to limit the rise time of the envelope to something the current limiter can cope with?Incidentally a pad of a few dB between the stages is a really good thing.73 M0HCN
