Capacitor Calculator is a handy tool must for all to keep in their pocket.
This calculator can convert the 3-digit value codes and alphabetical tolerance codes found on some capacitors into the corresponding value and vice versa.

Features:

Capacitor code formats:
104
104A
1R2 or 1P2
1R2A or 1P2A
1N2
1N2A

Capacitance formats:
xxxxx pF
xxxxx nF
xxxxx µF
x denotes integer from 0 to 9.

Example--
Code: 102K
Capacitance: 1000pF
Tolerance: +-10%
