In view of the problems of over temperature protection, over current protection, over voltage protection, surge suppression and protection, the reliability and service life of small household electrical appliances are directly determined.
Here recommended series TGPTC, NTC, followed by parallel pressure sensitive resistance or TVS protection program.
NTC to solve the problem of surge suppression;
Pressure sensitive resistance or TVS tube to solve the overvoltage protection problems, such as lightning, ESD, etc.. Self recovery fuse TGPTC overcurrent and overtemperature protection from electron production problem. And with the tube to solve the problem of overvoltage and lightning current burn or TVS varistor varistor or TVS tube.
When a short circuit, high voltage surge, varistors or TVS tube, high current through the TGPTC, and the TGPTC resistance value increased rapidly to the current limiting protection varistors or TVS tube, so as to protect the whole system when the automatic recovery circuit, TGPTC power or disappeared after a fault into the normal working state of low resistance, this program has been applied and verified by long-term, is currently the best protection scheme.
