MZFLY universal overcurrent protection PTC thermistor
Hua Ju Electronics is a professional PTC thermistor manufacturer. The over-current protection PTC produced by Hua Ju Electronics is widely used in various electronic products. The PTC thermistor for over-current protection is an automatic protection against abnormal temperature and abnormal current. The restored protective element is commonly known as "resettable fuse" and "ten thousand times fuse". It replaces traditional fuses and can be widely used for overcurrent and overheating protection of motors, transformers, switching power supplies, electronic circuits, etc. PTC thermistors for overcurrent protection limit consumption in the entire circuit through sudden changes in resistance to reduce residual current values. . Traditional fuses cannot recover by themselves after the line is blown, while PTC thermistors used for overcurrent protection can return to the pre-protection state after the fault is removed, and can realize their overcurrent and overheating protection functions when a fault occurs again.

Introduction to MZFLY universal overcurrent protection PTC thermistor:
Hua Ju Electronics is a professional PTC thermistor manufacturer. The over-current protection PTC produced by Hua Ju Electronics is widely used in various electronic products. The PTC thermistor for over-current protection is an automatic protection against abnormal temperature and abnormal current. The restored protective element is commonly known as "resettable fuse" and "ten thousand times fuse". It replaces the traditional fuse and can be widely used for overcurrent and overheating protection of motors, transformers, switching power supplies, electronic circuits, etc. The PTC thermistor for overcurrent protection limits the consumption in the entire circuit through its sudden change in resistance to reduce the residual current value. .Traditional fuses cannot recover by themselves after the line is blown, while PTC thermistors for overcurrent protection can return to the pre-protection state after the fault is removed, and can realize their overcurrent and overheating protection functions when a fault occurs again.
1. Application scope:
Huaju Electronics overcurrent protection PTC thermistor is mainly used for overcurrent and overheating protection of [transformer (adapter)/primary coil/charger/digital multimeter/smart electricity meter/micromotor/transistor], etc., and is directly connected in series with the load In the circuit, when an abnormal condition occurs on the line, it can automatically limit the overcurrent or block the current. When the fault is eliminated, it will return to its original state. It is commonly known as the "10,000-time fuse" .
2. Features:
·Contactless circuit and component protection ·Automatic limiting of overcurrent
·Automatic recovery after troubleshooting ·No noise or sparks during operation
·Reliable and easy to use
3. Application principle:
Connect the overcurrent protection PTC thermistor in series in the power circuit. When the circuit is in a normal state, the current flowing through the PTC is less than the rated current. The PTC is in normal state and has a very small resistance, which will not affect the electronic ballast (energy saving). normal operation of protected circuits such as lamps, transformers, and multimeters. When the circuit current greatly exceeds the rated current, the PTC suddenly heats up and the resistance suddenly increases to a high resistance state, thus limiting or blocking the current and protecting the circuit from damage. After the current returns to normal, the PTC also automatically returns to the low resistance state, and the circuit returns to normal operation.
Overcurrent protection PTC thermistors are used in overcurrent protection application fields such as [transformer (adapter)/primary coil/charger/digital multimeter/smart electricity meter/micromotor/transistor]. Nanjing Huaju relies on its scientific research and technology Taking advantages in other aspects , it was the first to launch the WMZ12A product featuring high withstand voltage (V≥300V AC).
