Product 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.

Application
This component's applications are primarily focused on compressor motors requiring split-phase starting and higher-power single-phase motors.
Refrigeration system compressors (primary application)
Household refrigerator and freezer compressors: This is the most classic and widespread application. It provides starting torque for the refrigerator compressor and automatically disconnects the start winding after starting.
Room air conditioner compressors: Commonly used in the outdoor unit compressor of window or split-type air conditioners.
Dehumidifier compressors: The principle is identical to that of refrigerators and air conditioners.
Other single-phase induction motors
While compressors are the primary application, any single-phase motor requiring a starting auxiliary winding could theoretically be used, such as:
Certain water pump motors.
Large power tool motors (such as large electric saws and drills).
Fan motors in industrial equipment.
