Product Description

Jb Capacitors Company offer Trimming Potentiometers come in a variety of sizes and levels of precision.
For example, JBR****2 Trimming Potentiometers, multi-turn trim potentiometers exist, in which it takes several turns of the adjustment screw to reach the end value, allowing for very high degrees of accuracy.

JBR****2 Trimming Potentiometers Introduction
A trimmer is a miniature adjustable electrical component. Trimming Potentiometers can be variable resistors, variable capacitors, trimmable inductors. They are common in precision circuitry like A/V components, and may need to be adjusted when the equipment is serviced. Unlike many other variable controls, trimmers are mounted directly on circuit boards, turned with a small screwdriver and rated for many fewer adjustments over their lifetime. Trimmers like trimmable inductors and trimmable capacitors are usually found in superhet radio and television receivers, in the Intermediate frequency, oscillator and RF circuits. They are adjusted into the right position during the alignment procedure of the receiver.
Super Capacitors have also made critical inroads into electric powertrains. The virtue of ultra-rapid charging during regenerative braking and delivery of high current on acceleration makes the Super Capacitor ideal as a peak-load enhancer for hybrid vehicles as well as for fuel cell applications.
