Sure they'll do it...If you're willing to pay double or triple the cost. It might not be as easy as you think. the value is usually marked in white over the black carbon area that actually is the resistor. Underneath is just the white ceramic carr

You seem to pretty far from shore to begin thinking about boats and floatation devices. Most laser trimmers are used by: * Semiconductor fabricators * Resistive component fabricators * Hybrid circuit assemblers Component fabricators and hybrid [

Resistor Help Needed

Hi Everyone, I want to use LEDs in an enclosed box for edge lighting etched glass. There are 15 LEDs in a box and they are set up in 5 series of 3 LEDs. The LEDs are 3.5V 20Ma 8000mcd. I've worked out that I need an 82 ohm resistor for each series

Thanks for the reply Stevo...! I am looking at doing just that. I would really like to ID this component and repair this Pico board though... After several searches, I can't find any (3) element resistor or capacitor networks to match it. I'm hop

CERAMIC CIRCUITRY Starting with hybrid thick film circuits in 1965 at Sperry Flight Systems, I have been involved with ceramics (usually aluminum oxide) as the substrate material. Then, we developed "multilayer" circuitry (replacing "cordwood" module
