content: So as i was just getting ready to wire up 10 LED's on my project, bicolour red/green i realized i had made that foolish mistake. with 10 2N7000 low side transistors all I was going to drive was the common kathode to both colours. So I jumped on RS and for a whopping £2.00 each! found the one and only's:https://uk.rs-online.com/web/p/visible-leds/2285770/Fear not, someone on eBay has them for 1/10th the price but crikey are common anodes really that rare?Farnell had none and well for 10 LED's I can't go abroad.

content: Yea but for 10 the postage will be overwhelming. I'm just surprised (well I'm not actually) at the RS mark up.

content: Pretty much all RGB LEDs are common-anode, and so common that they may be similar cost to RG

content: Ah right, maybe that is why no one stocks them as they commonise on RGB. I'd rather not have that extra pin though as it would mess up the layout.

content: A while back I bought a $10 "grab bag" from Jameco that had a ton of older LEDs in it and in there and there must have been at least 10 probably more bicolor LEDs along with tons of other stuff. It was worth much more than $10 as they say. Are there 10 of the exact same kind? Would have to check. There might be. They aren't that bright but they have a kind of cool weird dimness to them.Quote from: Simon on November 18, 2018, 07:21:14 pmI would just use the RGB LEDs and leave the extra lead unconnected.

content: Quote from: Buriedcode on November 19, 2018, 04:30:33 amAh, now I'm on my computer I have looked, that is indeed a common anode. Could not find it at the time.As for big distributor yes I guess they are as they too are now in the game of selling things they don't hold in stock. They are owned by Conrad and some of their stuff is available on a 7 day lead time. This means when the wrong part arrives they have have to do the 7 days lead time again. I am waiting for a hot air soldering iron from them at work. The delivery date moved by 2 weeks without warning. Rapid are not rapid at all, just another pain in the arse UK distributor owned by and up it's own arse German one.

content: Quote from: Simon on November 18, 2018, 09:39:13 pmAs this is for a small volume then how about using an RGB LED and simply cutting the lead for the blue shorter than the red and green, if you don't plan to use it?I suspect it could be a supply problem, more than RS and Rapid being a pain. If common anode RG LEDs are not a commonly used part, then many distributors won't bother to stock them or occasionally order them and charge a premium.

content: I don't have veroboard space for the extra pin pitch so have ordered the common anode ones from rapid for about 10% the RS price........ Even if I cut a pin off it may not line up properly.
