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.
