MZ1 series is mainly used in household appliances power control circuit, in refrigerators, washing machines, air conditioners and other home appliances, power required for circuit control version, PTC used to control version of the input end, to prevent abnormal voltage input, instantaneous pulse, load short circuit or other abnormal conditions , the protection circuit successor, the typical application circuit is as follows:

   In normal operation, PTC access transformer front end, smaller PTC impedance has little effect on the line, does not affect the normal operation of the line, in the outside world is too large voltage, or transient current pulses through, at the cumulative effects of current and heat quickly into PTC high impedance, so that the subsequent circuit protected. Failure during follow-up transformer short-circuit or rectification, resulting in increased power output when the input current is also a sharp increase, PTC can quickly access to protected status. So that subsequent failure has been effectively controlled, reducing the degree of circuit damage.
