Description

Φ24mm adjustable resistance dimmer with switch potentiometer WH138-1

Application:

Ideal for multimedia, computer speaker, stereos amplifier, lighting regulation etc.

Description:

The carbon film potentiometers are formed by depositing carbon composition ink on an insulating body, which in most of the cases is phenolic resin. This is one of the most commonly used materials for the potentiometer that is quite cheap and has resolution better than the wire wound potentiometers. They have reasonable life and tolerable noise levels.

Features:

• Rotary type with switch

• Carbon composition

• Top adjustment

• 6mm knurled shaft

• Special tapers

Materials used for potentiometer:

Material Properties
Carbon composition Carbon composition ink molded on a substrate(phenolic resin). Most common material, low cost and reasonable noise and wear characteristics.
Wirewound Wirewound pots can handle high power,are long lasting and can be very precise. They have however a limited resolution and rough feel. Most used in high power applications (rheostats are often wirewound) or as precision pots.
Conductive plastic Very smooth feel and high resolution, can be constructed to perform millions of cycles. Can only handle a limited power and are expensive. Often used in high-end (audio) equipment where a high resolution and low noise are important.
Cermet Very stable, low temperature coefficient and handles high temperatures well. On the other hand quite expensive and often limited amount of cylces allowed(special long-life cermet pots also exist). Often used for trimpots which do not have to be adjusted often.

The taper of a potentiometer is normally indicated with a letter. The following table lists the used coding for potentiometer taper, different standards uses the same letters which can be confusing. It is always a good idea to double check the taper by measurement.
