Title: LED pricing
Post by: decy90 on December 17, 2007, 02:28:02 PM: Ok im just wondering how much exactly do you guys pay for your 0603 SMD(SMT) LEDs. Im looking at a pack of 20 ultra bright blue ones and the price is Â£3.49 with Â£0.49 for P+P.
What do you guys think and will i get them any cheaper?

Also do i need to run resistors with the LEDs? if so in series or parallel.. ?where can i get suitable resistors?

ok cool thanks... do you know where i can get them? any links would be helpful :) (i am putting the LEDs in my DS so im not sure what exact type of resistor i need other than values for it)
