MZ21-type PTC Thermistor

  • Description:    Mainly used in line (transformer, micro-motor, charger, instrumentation, home appliances, communications circuit) over the over-current protection.
Introduction
Part Name
MZ21-type PTC Thermistor


Features
Non-contact circuit and components to protect 
Automatically limit the flow 
Troubleshooting automatically restore 
Job without the noise-free spark 
Reliable and easy to use, long life


◆Applications
 Mainly used in line (transformer, micro-motor, charger, instrumentation, home appliances, communications circuit) over the over-current protection.
 MZ21- type PTC thermistor is connected in series in the load circuit, the circuit when abnormal, can automatically restrict or block current flow, when troubleshooting and then restore the original state. Specific action: When the circuit is in normal state, the flow through the PTCR current of less than rated current, PTCR in a normal, resistance is very small, will not affect the protected components / circuits work correctly. When the circuit current at much higher than the rated current, PTCR sudden fever, increase resistance to high resistance state, thus limiting or blocking current, protection circuits are not damaged. Current returned to normal, PTCR also automatically restore to the low resistance state, the circuit to resume normal work.
