Indication example

Color code of 5 color bands

When the standard resistance value follows E48 series or

96 series, color code of the resistors are indicated by five

color bands. Example below is 154 k .

Example 1

Color code of 4 color bands

When the standard resistance value follows E6 series, 12

series or 24 series, color code of the resistors are indicated

by four color bands. Example below is 15 k .

Example 2

The resistance tolerance is identified by a single letter in accordance with the following table and the code is placed just

before the resistance code in the following examples.

Fixed resistors whose resistance value and tolerance are indicated by color code follow the standard below.
