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

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%
