N N N Resistor with value in three digit format. e.g. "473" Value =
47*1000 = 47k Ohms.
N N N N 1 % Resistor with value in four digit format. e.g. "4752" Value
= 475*100 = 47k5 Ohms.
N N L 1 % Resistor with value in code, see below.
L N Capacitor with value in code, see below.
L N N Aluminum electrolytic with voltage rating in code then value, see
table below, e.g. F47 = 0.47µF 25 Volts .
N L N Aluminum electrolytic, see table below, e.g. 4E7 = 4.7µF 16 Volts.
N N L Aluminum electrolytic with value in code then Voltage rating, see
table below, e.g. 47D = 47µF 10 Volts.

The third character is the multiplier.
_ _Y 0.01 _ _A 1 _ _C 100 _ _E 10,000
_ _X 0.1 _ _B 10 _ _D 1,000 _ _F 100,000
So a 1% surface mount resistor with the code,
20C =158 *100 =15800 = 15.800k =15k8 Ohms

This is a small (8x3 mm) yellow axial "blob" w/hard (ceramic?) shiny
exterior. Markings:
FC4
9116
Presume the latter is date code. What is the value? A Google turned up
nothing I could find that might identify this code. Surely tolerance
markings
follow the value markings...
Ideas?
Thanks,
