Kt Kingtronics Trimming Potentiometer Applications

It is estimated that the output value of quartz components in 2019 and 2020 will be 34.0 and 3.52 billion US dollars, respectively.
It continues to grow steadily, and since it is mostly a customized product, there are no supply and demand gaps and significant price increases; quartz components continue to benefit from the trend of miniaturization, and most of the components are customized products, and customer demand is stable.

In 2020, it is estimated that due to the increase in demand for 5G mobile phones and Netcom equipment, the industry trend is expected to continue to grow steadily.
The production of quartz components was reduced in 1H19 due to Japanese manufacturers, and the market supply decreased.
What's more, it is estimated that some components will be tight in 2H20, which will cause a new wave of component price increases.

How about turning to Kingtronics, our Quartz Crystals can support you favorable price and stable L/T 3-5 weeks with RoHS certified.  Remain at your service!

Principle of Trimmer Potentiomerets

A fixed resistor with a mechanism to change resistance construct a trimmer potentiometers. The principle is with the changing of resistive element length according a wiper sliding, the resistance will be changed. Use this method, with same sectional area, the resistance can be changed relative to resistive element length, and products can be manufactured in low cost.



            R: Resistance [Ω] 
            ρ: Resistivity [Ω/m] 
            L: Resistive element length [m] 
            S: Resistive element sectional area [m2]

  • The position of contact point decide the length of resistive element.
    Resistance between No.1 and No.2 (R12) will become higher if contact point become closer to No.3.
  • For easy introduction, we drew the resistive element like a rectangular solid. Actually, almost resistive element is round shape 
    (U - shaped) .So the track of wiper is circle, and resistance is decide by the angle of wiper. 

Change in resistance of Trimmer Potentiometers

There is the relationship between wiper position (angle) and resistance in below figure.

The output wave is besed on below conditions.
Resistive element is round shape (U - shaped) /Single - turn/No whirl - stop.

Construction
Single - turn, no whirl - stop typ    The relationship between wiper position (angle) and resistance


Feature of Trimmer Potentiometers

By using trimmer potentiometers, it is no problem to set surrounding circuit constant roughly.
Would you please use trimmer potentiometers if it is difficult to decided on a resistance value in your circuit. You can design your circuit roughly and quickly as the result.

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.
