TR30 Typical Time To Trip At 25℃
The Time to Trip curves represent typical performance of a device in a simulated application environment. Actual performance in specific customer applications may differ from these values due to the influence of other variables.
Advantages Of 30V Resettable PTC Fuses
PPTC self-recovery fuse at room temperature zero power resistance can be made very small, large current products only a few milliohms, in the road power consumption is small, can be ignored, the volume is relatively small.
PPTC self-recovery fuses can be used in series for over current protection and temperature fuses in vulnerable circuits, with fast resistance mutation speed, in several ms orders of magnitude, small heat capacity, short recovery time, impact resistance, and up to 8,000 cycles of protection.
PPTC self-recovery fuse can be used as temperature fuse, so in the circuit to a certain extent, the performance of temperature fuse and temperature fuse function.The dual protection functions of over current protection and over temperature protection are realized in the circuit.
Cautions For PPTC Self-Recovery Fuse Storage
There is no limit on the storage life of PPTC thermistors for polymer self-recovery fuses. It can be preserved for a long time under normal conditions. If exposed to excessive moisture or high temperature, the performance of some specifications may change, such as solderability of tin and lead.
