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.

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.

Generally bridge rectifier is divided into full-bridge and half-bridge.

Half-bridge : Two half-bridge is a half bridge rectifier diodes sealing together. Two half-bridge circuit can be composed of a bridge rectifier. 

A half bridge may be composed of a transformer with a center tap full-wave rectifier circuit.

Full-bridge : Formed by full-wave bridge rectifier circuit connected by four rectifier diodes, and packaged as one composed of external insulation packaging.

In addition , Bridge Rectifier Package category: SMD series, Bridge series, Round Bridge Series, Flat bridge series, Square Bridge Series.

Kingtronics is one of the oldest professional manufacturers in China with ISO 9001: 2008. 

Our diodes and transistors are used widely in alarm, automotive, communications, power meter, ballast construction, terminal block, automobile electronics, TV, cash registers...
