Metal oxide Varistors ( MOV, Metal Oxide Varistor ) are voltage dependent resistors with symmetrical voltage-current characteristics which are designed to protect all kinds of electronic devices or elements from switching pulse or induced lightening surges. Its non linear characteristic with broad application range, mass production feasibility are gradually being used in various level of electric and electronic device from low to high voltages level protections ( AC11V- 1000 V as available ranges ).

Feb 7th, 2015 afternoon, our company organized colorful Annual Festive Dinner at the Yihao hotel.

Before dinner each department has prepared a variety of cultural programs. Sissy, May, Joyce, Olivia, Twiggy, Sunny from sales department brought a very wonderful Sketch comedy & Dancing< Running Apples > and won the best program Award again. Their show received mostly applause and laughter.

After dinner, ushered in the most exciting raffle, with the prize money of steadily rising, everyone's mood has become increasingly tense. Finally everyone get a red paper containing money as a gift.

Wish it will bring good luck to us at the beginning of 2015 ! Let's work harder and make better achievement in this new year!

The sky is blue, the grass is green, may we have our Halloween". When the kids sing it to you, yes, you have to prepare some sweets for its performance.

Halloween is contraction of All Hallows' Evening which is a Christianized feast initially influenced by Celtic harvest festivals with possible pagan roots. On this evening, the main task is to make up yourself horribly the same as these ghosts or devils in order to scare them away.

Pumpkin lanterns, candies, costume parties, trick-or-treating...All of these are the most popular activities durning this carnival. How did you celebrate it? Any new programs?

Sincerely hope you and your families enjoyed a wonderful & joyful holidays.

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.
