Circuits Automatic Degaussing MZ71-18RMB 18 OHM 60C PTC Thermistor
Description
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.
