New varistor material: Journal of Applied Physics: Vol 64, …

A composite varistor material containing silicon carbide, a conductor, and an insulator has been developed. The material has rubberlike flexibility and is easily formed. A higher leakage resistivity (∼10 1 2 Ω cm) and greater nonlinearity (∼10) than for silicon carbide varistors permit the material to be used as a gapless surge suppressor.

What is the difference between a thermistor resistor and …

A resistor is a resistance of a set value that will maintain that value (within its stated tolerance) within its working temperature range. A thermistor is a resistor whose resistance varies with temperature. There are 2 types of thermistor: NTC (

What is Varistor ? - Working, Appliion & …

The crystals of semiconductor material such as silicon carbide are used with the ceramic binder, and both are pressed between electrodes, and the entire crystal is sintered at a higher temperature. The temperature of manufacturing and sintered temperature plays a vital role in shaping electrical characteristics of varistors.
