MMBT3904 and MMBT3906 are a bipolar (BJT) small signal transistor in a SOT−23-3 type surface mount package, they are designed for general purpose amplifier and switching applications. The useful dynamic range extends to 100mA as a switch and to 100MHz as an amplifier. As complementary types the NPN transistors MMBT3904 is recommended.

In response to demand market, Kingtronics small quantities transistors can be shipped immediately. The common application is signal Processing, Power Management, Portable Devices, Consumer Electronics, and Industrial.

About

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.
