Product background knowledge:

PTC stands for Positive Temperature Coefficient, which means positive temperature coefficient. It generally refers to semiconductor materials or components with a high temperature coefficient. The PTC we usually refer to is a temperature coefficient thermistor, abbreviated as PTC thermistor. PTC thermistor is a typical semiconductor resistor with temperature sensitivity. When it exceeds a certain temperature (Curie temperature), its resistance value increases step by step with the increase of temperature. Ceramic PTC is a semiconductor ceramic mainly composed of barium titanate (or strontium, lead), with a small amount of donor (Y, Nb, Bi, Sb), acceptor (Mn, Fe) elements, and glass (silicon oxide, aluminum oxide) additives added, and sintered. Ceramic PTC has low resistance below the Curie temperature.

1、 Product Overview:

The PTC/PTRC-500 high-temperature thermistor material parameter measurement and analysis system is capable of testing different types of PTC samples. Under different voltage and temperature conditions, it can obtain the resistance temperature characteristic curve, volt ampere characteristic curve, and resistance voltage (voltage effect curve) of different types of samples. It is possible to analyze the curves of the resistance and resistivity of the tested sample as a function of temperature and time, as well as the volt ampere and current time characteristics at different temperatures.
