SMD ceramic capacitors are sometimes marked with
a code, consisting of one or two letters and a digit. The first letter if present
is a manufacturer code (i.e K for Kemet, etc.), the second letter the mantissa
and the digit the exponent (multiplier) of the capacitance in pF. For example
**S3** is a 4.7nF (4.7 x 10³ pf) capactitor from an unknown manufacturer,
while** KA2** is a 100 pF (1.0 x 10² pF) capacitor from Kemet. *Thanks
