Details:
Encased type PTCR for degaussing loop of colour TV chromoscope,MZ72 series--MZ72 9ohm

Brief Introduction:
MZ72 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.Product 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 achieve degaussing purpose.

In order to eliminate image distortion,abnormal colour or irregular colour plaques caused by the stray magnetic field, automatic degaussing loop is designed for colour TVs and colour Monitors,which is combined with PTC thermistors and degaussing coil. Its principle is incentiving energy when turning on each time, and then removed energy gradually after normal operation, which can effect electron beam by partial coil, and do not suffer influence of any outside stray magnetic field.
