The standard color code provides all necessary information re-
quired to properly identify color coded resistors and capacitors.
Refer to the color code for numerical values and the zeroes or
multipliers assigned to the colors used A fourth color hand on
resistors determines tolerance rating as follows: Gold = 5%.
silver = 10%. Absence of the fourth band indicates a 20%
tolerance rating.

The physical size of carbon resistors is determined by their
wattage rating. Carbon resistors most commonly used in Heath-
kits are V2 watt. Higher wattage rated resistors when specified
are progressively larger in physical size. Small wire wound
resistors l/fi watt, 1 or 2 watt may be color coded but the first
band will be double width.

The tolerance rating of capacitors is determined by the color
code. For example: red = 2%. green = 5%. etc. The voltage
rating of capacitors is obtained by multiplying the color value
by 100. For example: orange = 3 X 100 or 300 volts Blue =
6 X 100 or 600 volts.

In the design of Heathliila. the temperature coellicient of ceramic
or mica capacitors is not generally in critical factor and there-
fore Heathkit manuals avoid reference to temperature coelli-

cient specifications.
