Trimming Potentiometers:
An electrical mechanical device with three terminals. Two terminals are connected to the ends of a resistive element and one terminal is connected to a movable conductive contact which slides over the element, thus allowing the input voltage to be divided as a function of the mechanical input. It can function as either a voltage divider or rheostat.

Wirewound Trimming Potentiometer:

A trimming potentiometer characterized by a resistance element made up of turns of wire on which the wiper contacts only a small portion of each turn.

Non- Wirewound Trimming Potentiometer:

A trimming potentiometer characterized by the continuous nature of the surface area of the resistance element to be contacted. Contact is maintained over a continuous, unbroken path. The resistance is achieved by using material compositions other than wire such as carbon, conductive plastic, metal film and cermet.

Power management refers to how to effectively allocated to the power supply system of different components. Power management is very important to rely on battery power of mobile devices. Power management technology also called power control technology. It belongs to the category of power electronic technology. Nowadays it has been widely applied to industry, energy, transportation, information, aerospace, defense, education, culture, and many other fields.

Our diodes and bridge rectifiers can be used for power management.

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.


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.

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
