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.
