Need Help About capacitor value.

[WAZ]

In my Electro Lab there is many types CAPs, we used to mesure its value
by KpF(KilliPicoFeradey) , on ceramic capacitor sometimes its is 102 =
10 Kpf, 502 , can any body give me corevt method of finding value in
KpF , when there is no Color Codes.

You might measure it in "KilliPicoFeradey". Those with some training
would measure them in Farads (be it pico-, micro-, nano-, milli- or
even just farads).


The numbers are :

1st significant digit
2nd significant digit
multiplier

Answer in picofarads

102 = 1000 picofarad = 1 nanofarad = 0.001 microfarad.

There are sometimes letters after the numbers. J and K are the most
common, and they specifiy the tolerance of the device, 5% and 10%
respectively.

I don't think so.

on ceramic capacitor sometimes its is 102 => 10 Kpf,

102 is 1nF or 1000pF, Kpf is not a commonly used unit.

502 , can any body give me corevt method of finding value in
KpF , when there is no Color Codes.

same as resistor colour code, the last digit is the power of 10 to multply
the preceeding number by.

502 would be 5nF
