MZ1 series PTC thermistor

Products: MZ1 series PTC thermistor is a abnormal temperature and current automatic protection, automatic recovery protection elements, commonly known as "resettable fuse" "million times the fuse." AMPRON production MZ1 series PTC thermistor for common line overcurrent, overload protection, such as transformers, micro-motors, switching power supplies, chargers, adapters, instruments, meters, electronic coil, control panels, home appliances, air conditioners, microwave ovens, etc. over-current, overload, short circuit protection. Application: The principle is shown in Figure 2: When the circuit at a normal state, the current is less than the rated current PTC, PTC in the normal state, the resistance is small, it does not affect the normal operation of the circuit to be protected. When the circuit large fault current is greater than the rated current, PTC suddenly fever, a high-impedance state, the circuit relatively "off" state, to protect the circuit from damage. When troubleshooting, PTC will automatically restore its low resistance state, the circuit to resume normal work. (During normal operation) selection of PTC thermistor as overload protection device, first make sure the line maximum normal operating current (PTC thermistor is not operating current) and PTC thermistor installation position maximum ambient temperature, followed by protection of current (PTC thermistor is operating current), the maximum operating voltage, rated zero-power resistance, but also should consider the element dimensions and other factors.
