At the beginning of our company's establishment, we had only one factory and mainly specialize in trimming potentiometer manufacturing.

After 23 years' development, now we own 2 factories with ISO/SGS/UL certificates. In order to meet the requirements of our customers and overseas markets, we constantly introduce new technologies and develop new products. Here I list out our 4 parts series and their application fields. Look forward to your business chances!

Kingtronics surge arrester divides into two kinds: 2-Electrode arresters and 3-Electrode arresters.

What is surge arrester? It is a product installed near the end of any conductor which is long enough before the conductor lands on its intended electrical component. The purpose is to divert damaging lightning-induced transients safely to ground through property changes to its varistor in parallel arrangement to the conductor inside the unit.

Surge arrester is also called a surge protection device (SPD) or transient voltage surge suppressor (TVSS). They are only designed to protect against electrical transients resulting from the lightning flash, not a direct lightning termination to the conductors.

SKT--Surge Arrester:
SKT-2R-230A6L Bulk RoHS
SKT-3R-230AL Bulk RoHS

Application: distribution system, protector, power station equipment, satellite receiver, server, communication system...

Dear Honored customers,

Kingtronics produce high quality tantalum capacitors. we can supply radial tantalum capacitors in military level.

We are going to keep some stock material, semi-finished products to shorten lead time.

Could you pls send me your regular ordered tantalum capacitors items ? We are collecting some common values which you need often.

TKT--Dipped tantalum capacitors, radial type 
10uF 35V +/-10% P: 2.54mm Bulk RoHS 
2.2uF 35V +/-10% P: 2.54mm Bulk RoHS 
4.7uF 35V +/-10% P: 2.54mm Bulk RoHS 

 We can also offer other strong capacitor as below, especially radial multilayer ceramic capacitors, our price is unbeatable in the market.

MKT--series Radial multilayer ceramic capacitors, 3-4 weeks lead time, excellent prices
AKT--axial lead, multilayer ceramic capacitors
HKT--SMD, high voltage multilayer ceramic capacitors 100V to 4000V 
CKT--SMD tantalum capacitors

Wish you a nice day and looking forward to your kindly inquiry. We will do all the best to help you cost down!

Dear Valued customers,

As you know, Kingtronics are ISO manufacturer of capacitors for many years.

The strongest capacitor is Multilayer Radial Ceramic Capacitor. Our price, quality, lead time and service are excellent.

If you are buying capacitor brand like AVX, Kemet, Murata.... We can offer equivalence and help you cost down.

Kindly check below description in different language and see if you have inquiry/order on 
hand ? We are your best choice!

Let's strive for the future good business and profits!!

Kingtronics is potentiometers manufacturer since 1990. Trimming potentiometers are Kingtronics' first products. On Kingtronics' trimming potentiometers body, we mark "Kt" due to insufficient space. Actually our registered brand in Hong Kong is “Kingtronics and Kt”.

Now, Kingtronics upgrades trimming potentiometers packaging box . There are 3 sizes of different packing box, which can be used for all types of trimming potentiometers .We choose blue as the color of Kingtronics. Our website, catalog, poster, envelope, company logo and all other things related to Kingtronics, we choose blue. Blue stands for our Kingtronics people spirit --- Innovation, efficiency and foucs

Compared with out previous one , we list all the strong products of trimming potentiometers on the box. Our brand name and contact way are also printed on it. Therefore, whether you are interested in other products of potentiometers, or have any inquiry, you can contact us rapidly.

Below link provides more information about trimming potentiometers, hoping it is helpful to you.
