Kt Kingtronics Tells You Trimming Potentiometers's General Electrical Characteristics Ⅰ

31 Dec 2015

TOTAL RESISTANCE: (Rt)
The dc resistance between the input terminals with the wiper positioned to either end stop, or in dead band for continuous rotation potentiometers.

ABSOLUTE MINIMUM RESISTANCE: (Rm)

The resistance measured between the wiper terminal and each end terminal with the wiper positioned to give a minimum value.

END RESISTANCE: (Re)

The resistance measured between the wiper terminal and an end terminal when the wiper is positioned at the corresponding end of mechanical travel.
Absolute minimum resistance and end resistance are synonymous for continuous rotation trimmers.

TEMPERATURE COEFFICIENT OF RESISTANCE: (TC)

The unit change in resistance per degree celsius change from a reference temperature, expressed in parts per million per degree celsius as follows:



Where:
R1 = Resistance at reference temperature in ohms
R2 = Resistance at test temperature in ohms
T1 = Reference temperature in degrees celsius
T2 = Test temperature in degrees Celsius

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.
