Dimensions of MZ71 series PTC Thermistor is provided for use in color TV degaussing applications. These include detailed measurements and part identification to ensure proper selection and compatibility.

Working Principle of MZ71 PTC Resistors in Degaussing Circuits

• On power-up, the low resistance allows high current through the degaussing coil.
• This current produces a strong magnetic field to demagnetize the CRT shadow mask.
• As the PTC Termistor heats up, resistance increases, gradually reducing the current and completing degaussing.
• The PTC Thermistor stabilizes at a higher resistance, minimizing residual magnetic fields.
