Benefits of Carbon Composition

Carbon composition resistors are made from a moulded carbon powder that has been mixed with a phenolic resin to bind and create a uniform resistive body. It is then surrounded in an insulating case after attaching end leads. Carbon composition resistors are used in applications in which the initial tolerance does not need to be any closer than +/- 5% of the value.

What does the power rating mean?

The power rating of a resistor describes the amount of power that the resistor can dissipate safely.

What do the colours mean?

Each of the colour bands has a specific meaning. The first two colours give the base value of the resistor, the next gives the multiplier and the final band the tolerance. If a resistor has five bands, it is a more precise resistor, in which the first three bands represent the base values, and the fourth and fifth represent the multiplier and tolerance respectively.
