Resistor color code guide

E-series of preferred numbers — IECwhich defines series of preferred resistance values.

Electronic color code

VZR power resistor 1. Orange Blue Yellow Gold k color code: Red Red Orange Gold 24k resistor color: Violet Green Orange Gold 4 band 82k resistor colors: Thick film resistors became popular during the s, and most SMD surface mount device resistors today are of this type.

An aluminium-encased power resistor rated for dissipation of 50 W when mounted on a heat-sink Resistors required to dissipate substantial amounts of power, particularly used in power supplies, power conversion circuits, and power amplifiers, are generally referred to as power resistors; this designation is loosely applied to resistors with power ratings of 1 watt or greater.

Special carbon film resistors are used in applications requiring high pulse stability. The same resistance is encoded by: The insulation of the wire may be solidly colored, or where more combinations are needed, one or two tracer stripes may be added.

The coding is defined in the international standard IEC Other color codes are used in the UK and other areas to identify building wiring or flexible cable wiring. Combination of more than one resistor groups is called network resistor. They usually absorb much less than a watt of electrical power and require little attention to their power rating.

A typical application would be non-critical pull-up resistors. Excessive power dissipation may raise the temperature of the resistor to a point where it can burn the circuit board or adjacent components, or even cause a fire.

Orange White Orange Gold 43k yellow, orange, orange, gold 47k color code: Resistors with higher power ratings are physically larger and may require heat sinks. The color code is given by several bands. Intermediate-frequency tuned transformers were coded blue and red for the primary and green and black for the secondary.

Green Blue Orange Gold 62k blue, red, orange, gold 68k blue, gray, orange, gold 75k color code: Orange White Orange Gold 43k yellow, orange, orange, gold 47k color code: Resistor can be open. Red and black are frequently used for positive and negative of battery or other single-voltage DC wiring.An electronic color code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.

A separate code, the pair color code, is used to identify wires in some telecommunications cables. Different codes are used for wire leads on devices such as transformers or in building wiring. Jul 25,  · This guide shows an easy illustration on using resistor color codes.
