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...

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.
