I have some questions about interpreting part names:
Resistors: "R_270_0402_F" is a 270 Ohm resistor, 0402 package. But what does the 'F' signify? How about 'G', or the lack of a letter at all? Do these have something to do with tolerances, or type (thick film, thin film, etc.) ?
Inductors: "L_1N8_0402_S" is a 1.8 nH inductor in an 0402 package. What does the 'S' indicate? Or the 'J' ?
Capacitors: "C_1U_0402_X5R_K_6P3" is a 1 μF capacitor in an 0402 package. "X5R" ("X7R", "NP0") refers to the type/temperature characteristic. The following are educated guesses from reading datasheets: 'K' refers to capacitance tolerance: K = +/-10%, J = +/-5%, C = +/-0.25pF. Am I correct, and what about 'L'? The final number must refer to rated voltage, (10 = 10V, 25 = 25V, etc.) I assume "6P3" mean 6.3V.
Thanks for your help.
