Kt Kingtronics Trimming Potentiometers

The combination of proprietary cermet element technology, precious metal brush contacts and 
swaged pin element connections used in BI trimmers permits the manufacture of precision, high quality trimmers that span the resistance range from 10 ohms to over 5 megohms. The small size and planar 
construction of these trimmers minimize stray circuit reactances and permit the trimmers to perform well in many high frequency applications.


Leadscrew

Precision brass leadscrew cuts its own grooves in the teflon rotor so that the operation of the rotor is 
free of backlash. Setability is excellent.

Sealing Grooves
Leadscrew has specially cut grooves to ensure a watertight seal.

Ceramic Substrate

High density substrate provides an excellent base for the element and is a good conductor of heat.

Cermet Element

BI’s proprietary cermet element matches the materials in the wirebrush so that CRV is minimized and 
the high temperature setability is excellent.


Swaged Pins

BI’s pin connections, which are swaged to the substrate, are free of solder and maintain high 
conductivity with time and temperature cycling.
