IDENTIFYING RESISTOR VALUES
Use the following information as a guide in properly
identifying the value of resistors.
IDENTIFYING CAPACITOR VALUES
Capacitors will be identified by their capacitance value in
pF (picofarads), nF (nanofarads), or
μF (microfarads).
Most capacitors will have their actual value printed on
them. Some capacitors may have their value printed in the
following manner.
Second Digit
First Digit
Multiplier
Tolerance
The above value is 10 x 1,000 = 10,000pF or .01
μF
The letter K indicates a tolerance of +10%
The letter J indicates a tolerance of +5%
Note: The letter “R” may be used at times to signify a decimal
point; as in 3R3 = 3.3

Electrolytic capacitors have a positive and a
negative electrode. The negative lead is
indicated on the packaging by a stripe with
minus signs and possibly arrowheads.
Warning: If the capacitor is connected with
incorrect polarity, it may heat up and either
leak, or cause the capacitor to explode.
