Description
MZ73 series degaussing PTC thermistors are specially designed for application in automatic degaussing circuits of colour TV& acute;s,colour Monitors and other CRT degaussing loop etc.,which can eliminate image distortion,abnormal colour or irregular colour plaques caused by the stray magnetic field.With the characteristics of low residual current and good reliability.The trend of automatic degaussing PTC thermistors is developed to small size, low resistance,low residual current,high resistance to impact and high reliability.
PTC Thermistor Application:
colour TV& acute;s, colour Monitors and other CRT degaussing loop
Working principle:
degaussing PTC Thermistor is using its current-time characteristics of the work. String of degaussing circuits, because very small initial resistance of PTC thermistor, big initial current through the degaussing coil that produce a powerful alternating magnetic field in the coil. PTC thermistor resistance then rise due to its own fever, the current in the circuit will be attenuation gradually, and make the coil alternating magnetic field also weakens to achievedegaussing purpose.
