MZ7 PTC thermistor are used as automatic degaussing components in color TVs and color displays, and current-limiting components in AC circuits.
MZ71, 72, 73 series PTC thermistors and Degaussing PTC Thermistorare mainly used in degaussing circuits of color TVs, displays and other CRTs, which can effectively eliminate image distortion, abnormal colors or irregular images caused by stray magnetic fields, and make color The picture is more vivid and clearer. It has the advantages of low residual current and good reliability. At present, the development trend of automatic degaussing PTC thermistors is small size, low resistance, low residual current, high impact resistance, and high reliability.
In order to eliminate image distortion, abnormal colors or irregular images caused by stray magnetic fields, automatic degaussing circuits are designed in color TVs and color displays, which are composed of PTC thermistors & degaussing resistors and degaussing coils. The principle is to add energy every time when the machine is turned on, and gradually remove the energy after normal operation, so that the electron beam is affected by the deflection coil without being affected by any external stray magnetic field. When the machine is turned on, the PTC thermistor & degaussing resistor In a low resistance state, a large current is formed in the degaussing coil, and the magnetic field line is greater than 350At, which can effectively eliminate the influence of stray magnetic fields. Then the PTC thermistor & degaussing resistor enters a high resistance state under the influence of a large current, the loop current is automatically attenuated, the residual current is very small, and it is almost open, and the magnetic field line is reduced to below 0.03At, reaching the acceptable limit under normal operation.
