Hi Piotr, We had the same problem before. Each engineer created his own name and after while nobady knows what it is. We started to use our own coding system of components using special code matrix. We use main features of componets like body shape,

Hi. Our X4 is posting the attached error code. In the reference menu, the table dances to align with the SMD stencil and the shuttled PCB. During this activity, hearing some new mechanical ticking sounds that were not hear before. Any suggestions on

Well John here is the situation: I need to place an infrared transistor (optical element) with a tolerance of +/-.003", this is not a problem. A lens is positioned over the optical element and snapped to the PCB via three holes that have a toleran

How do you tell what percent a SMT resistor is?

An explanation that could possibly help (depending on the exact code on these parts) is on http://www.marsport.demon.co.uk/smd/res.htm. The author of this ends the page with a "Personally, I'd check with an ohm-meter!". Daan Terstegge http://www.smt

Identify SMD IC

Electronics Forum | Mon Jan 12 14:54:58 EST 2015 | nkrcompany

Hi All, I would like to ask some help from you. It would be very important for me to identify a bad IC. It is located in a 2,4GHz radio frequency receiver, maybe the IC is some kind of low noise amplifier, but I'm not sure about it. It has 5-pin, see

Jack: You should use your components promptly. Don't store 'em, only bad things will happen to them. 1 You should store all your components, not just your SMD reeled components, so they are not damaged or their solderability decreased. Check the
