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.

Kingtronics other trimming potentiometer:
3296 3006 3266 3362 3323 3329 3309 3590 3540 065 063 C3305 

Example1: Flicker adjustment for LCD (Liquid - crystal display)
To adjust the reference voltage (VCOM) of LCD.
With inappropriate reference voltage, there will be flicker on LCD screen.
Use trimmer Potentiometers to adjust reference voltage for flicker restraining.

LCD has some flickers if the voltage is not suitable for LCD.
 

You can reduce the flickers when you adjust the voltage by using trimmer potentiometer.
 

Example2: Gain adjustment for Blu-ray, DVD, CD disc reading optical pick - up.

As record media Blu-ray, DVD and CD etc. usually be used, and we use optical pick - up for the data 
reading and writing from disc. In an optical pick - up, there is a light - sensitive element to detect reflected 
light from disc.And a trimmer potentiometer is used to adjust the sensitivity of this light - sensitive element.

Circuit example Playback system device (ex, DVD, CD, playback)

Example3: Sensitivity adjustment for sensor products.

There are all kinds of sensors around our life.

• Lights turn on automatically when human be detected.
• Smoke detector for fire preventing.
• Parking assist system for distance from car to wall.
• Product detection sensor in factory.
   

 For these sensors, trimmer Potentiometers are used for suitable sensitivity.

A trimmer  is a miniature adjustable electrical component. It is meant to be set correctly when installed in some device, and never seen or adjusted by the device's user.
 
Trimmers can be variable resistors (potentiometers), variable capacitors, trimmable inductors. They are common in precision circuitry components, and may need to be adjusted when the equipment is serviced.
 
Trimmers are mounted directly on circuit boards, are usually found in superhet radio and television receivers, in the Intermediate frequency, oscillator and RF circuits.
 
In one words, trimmers are in wide used in our daily life, so the demand of trimmer is huge in the market!

Kingtronics is a manufacturer of Trimming potentiometer since 1990, we are one of the oldest factory for trimming potentiometer.
 
All products are RoHS compliant under our own brand "kingtronics" with registered trade mark "Kt" on the body.

We produce all parts with mature technology, quality is very good with ISO & SGS certifications available, and price is quite competitive in the market!
