PTC THERMISTOR

APPLICATION CIRCUIT

This is a basic degaussing circuit, if residual currents requested zero, this circuit usually a switch When necessary the switch is turned off.

Current-Time Characteristic(Dynamic Characteristic)

Heating element (1) causes the resistance value of Element (2) to increase and make the stable current extremely small, Thus in many case.

The circuit is designed to be linked to the power switch so that degaussing is performed automatically when the power is turned on.

When excessing power is applied to the themistor,a large current flow momenarily,then the self-heating feature of the themistor causes the

resistance value to increase and the current value to decrease Thus, the thermistor controls degaussing function ideally.
