Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi All,

I got a collection of LED bar graph modules a while back.
The DIL type with 8 separate LEDs in each.

Figured I'd be able to just grab some 100 Ohmish resistor arrays to make them easy to implement.

Was figuring arrays with 1 common pin & 8 "R" pins would be an easy find...

Tore some hair out & gave up.
Lots of different matrix's popped up, but what I was after seemed to elude me.

Can anyone point me in the right direction?

Was using searches like "SIL resistor network or array" but getting the wrong hits.

Cheers

Phil.

What sort of power rating you looking for? ? Each or total??
I think it works !!

Thanks for that.

Now that I can link to a Data Sheet, I can see that what I want is termed "Bussed Resistors" on page 2 of the data sheet.

That was the bit that was stumping me; the various configurations within the packages.

Phil.

These things are known by a great many different names, which makes finding something frustratingly difficult.

At least on e-bay, try using search terms like "4K7 9 pin" seemed to work.
Just ordered a big bag of these beasties myself.

By big bag, do you mean a bag of mixed values?

If so wouldn't mind a link to the listing.

All the same value, but pretty cheap.
