TRG (600V) series self recovery fuse PPTC plug-in fuse PTC

PPTC self recovery fuse (plug-in) is a high polymer positive temperature coefficient thermistor. Compared with ceramic PTC thermistor, it is suitable for overcurrent and overload protection circuit with high current. When in use, PPTC self recovery fuse with appropriate rated current is selected to be connected in series in the circuit to be protected. When the line fails and the current increases greatly, PPTC changes from low resistance to high resistance due to its own heating, so as to reduce the current in the circuit and protect the circuit. When the fault is eliminated, the temperature of PPTC itself decreases, returns to the initial resistance, and the line returns to normal operation.

1 application field

The product has small volume, fast corresponding time and small residual current

Notebook, computer motherboard and driver

Space related to lamps, motors and automobiles

Low zero power resistance: the self resetting fuse has low impedance, small power loss and low surface temperature during normal operation.

Fast over-current protection speed: due to its own material characteristics, the response speed of over-current state of self resetting fuse is much faster than that of other over-current protection devices.

Self locking operation: the self resetting fuse is in the overcurrent protection state and locked in the high resistance state with very small current. The low resistance state will be restored only after the power supply is cut off or the overcurrent disappears.

Automatic reset: after the self resetting fuse plays the role of overcurrent protection (troubleshooting), it will reset automatically without disassembly and replacement.

High current resistance: the self resetting fuse has excellent high current resistance, and some specifications can withstand 100A current impact.

Application: PPTC has a wide range of applications and can be used in various electronic products, communication products, power supplies, etc.
