RL0201E014M300K 0201 PTC Resettable Fuse | 14V 300mA Overcurrent Protection | RUILON

RUILON

The RL0201E014M300K is an ultra-compact 0201 PTC resettable fuse engineered for reliable overcurrent and short-circuit protection in miniature electronic circuits. With a 14V operating voltage and 300mA hold current, it offers fast response to fault conditions and automatically resets once the fault is cleared. Its extremely small 0201 footprint makes it ideal for high-density PCB layouts where space is limited. Designed for low resistance, stable performance, and long service life, this device is widely used in consumer electronics, IoT modules, and portable systems requiring efficient and reusable circuit protection.
