0603 SMD LED Resistors?? HELP!
« on: March 26, 2012, 01:30:14 PM »
I have been looking every where around the web and no on seems to have done this besides in kits which is lame save money and do it you self so i'm trying to hook up 0603 leds around my thumbsticks on my controller to have lighted thumbstick and I wired them up and it didnt go so well..  :censored: ing things ended up buring 2 of them out right away so I am trying to figure out what size of ohm resistor i should use? and could I wire them in parallel or series..? I was thing 51k ohm resistor per led (I'm using 4 leds per thumbstick) and then I have them switched by a transistor.. So pretty much need some kind of wiring diagram or somthing! Thanks!

I use this to figure out what ohm resister to use

http://led.linear1.org/led.wiz

also you don't need to use smd resistors you can use normal through hole.

if you really want smd resistors you can get them from digi-key

I was using them sites before just wanted to verfiy I goin about it right... I was also wondering could I hook SMD 0805 leds to 0805 SMD resistors? like solder them right on one another or sould there be wire spacing?

I guess u could solder them directly together, I generally solder the resistor to the power source and wire to the led from there. But I use through hole resistors.
