Top adjust multiturn variable resistor trimmer potentiometer 3296W
Description:
Cermet trimmer potentiometer are widely used, particularly for trimmer resistors. The name cermet is derived from the fact that the resistive element is made from ceramic and metal. The resistive element is made from a mixture of fine metal oxides or precious metal particles and glass in a viscous organic material. The resulting paste is applied to the substrate and fired to solidify the mixture.
Cermet variable resistors are ideal for trimmer resistors because they have a low to medium adjustment life, and they often have temperature coefficients of around ±100ppm/°C.
Application:
Multi turn trimmer potentiometer commonly found in user control circuits; volume, speed, brightness, etc…
