Over-load Protection 270 V PTC Thermistors / 2 Pins Posistor Thermistor

 

Quick Details

 

·Optional on 3 construction, resin coated leaded form, 2 pins, dual PTC 3 pins.

·Nominal resistance from 3 ohm to 36 ohm.

 

Outlook and Dimension (mm)

 

 

Descirption

 

PTC thermistor degauss the shadow mask of color picture tube by reducing the alternating current flowing through the degaussing coil within a short period of time. A large difference between inrush current and residual current is crucial for good degaussing. We can provide leaded and housed PTC thermsitor for degaussing purpose. Particularly, in a double PTC, a PTC connected to the coil, as compared to a single PTC, this configuration permits the residual current to reduce further.

PTC degaussing principle

By using dual PTC thermistor, residual current is significantly reduced.

 

 

Application

 

Degaussing of picture tube, such as color TV, monitor.
