Component Designator's (PCB Design)

Hey everyone.

I just wanted to find out if there's a standard, or to get people's thoughts on component designators when it comes to PCB design.

I understand that values shouldn'y be printed on a silk screen just in case component values need to change.

Here's what I have;
B for siren, buzzer, speaker
C for Caps
D for Diodes, LED's
H for heatsink
IC for Intergated circuits, voltage regulators, microcontrollers, logic IC's and mosfet drivers etc..
J for connector, Jumper and Header pins
L for inductor
R for Resistors, resistor networks, and Variable Resistors
S for switch, push button,
T for Transistors, MOSFETs, JFET's
TP for test point
X for Cystal

So i'm only guessing, please correct/suggest any mistakes/changes
I will update the list as I get feedback.
 
The only thing I see incorrect in the original list is the transistor symbol is Q, not T, and I see U now instead of IC for a chip. That Wiki article is pretty complete.

Click to expand...

Eagle uses T for some FET parts. I don't mind T or Q. I do prefer IC though.

The most important thing is to be consistent. Especially on one board (or it becomes a mess) but also across multiple boards you design.
