Application and Benefits of MZ73 Series PTC Thermistor
Versatility in CRT Displays
The MZ73 series PTC thermistors are engineered for use in color TVs, monitors, and other CRT degaussing loops. These thermistors generate a strong alternating magnetic field, counteracting unwanted magnetic interference and ensuring optimal image quality.
Efficiency and Reliability
These thermistors feature a design that allows for a large inrush current initially, followed by a gradual reduction in current as the thermistor heats up. This ensures effective degaussing with minimal residual current, contributing to lower power consumption and enhanced overall efficiency.
Advantages of MZ73 Series Thermistor PTC
- Large Inrush Current: Ensures effective initial degaussing.
- Low Residual Current: Minimizes energy consumption.
- High Withstand Voltage: Durable under high voltage conditions.
- Compact Design: Suitable for PCB mounting, saving space.
- Impact Resistance: Withstands shocks and vibrations.
- RoHS Compliant: Environmentally friendly and safe.

Key Features of PTC Thermistor MZ73 TV degausser
Working Principle
Current-Time Characteristics
The MZ73 series operates based on its current-time characteristics. Initially, the PTC thermistor has low resistance, allowing a large initial current to flow through the degaussing coil. This generates a strong magnetic field necessary for degaussing. As the thermistor heats up, its resistance increases, reducing the current and the magnetic field gradually, achieving the desired degaussing effect.
