JRN30V Series PPTC Resettable Fuse | 30V Rated Polymeric Protection for Battery, Power & Control Circuits
The JRN30V Series is a Polymeric Positive Temperature Coefficient (PPTC) resettable fuse designed for 30V DC systems. Upon overcurrent events, it transitions to a high-resistance state to limit current and automatically resets when power is removed and the device cools down. With hold current (I<sub>hold</sub>) ratings from 100mA to 3A, the series offers fast response and excellent durability, ideal for battery packs, DC ports, industrial I/O, LED strings, and automotive auxiliary systems.
