RL0201E009M101K 0201 PTC Resettable Fuse | 9V 100mA Overcurrent Protection | RUILON

RUILON

The RL0201E009M101K is an ultra-compact 0201 PTC resettable fuse designed for reliable overcurrent and short-circuit protection in miniature electronic circuits. With a 9V operating voltage and 100mA hold current, it provides fast fault response and automatic reset after the fault condition is cleared. Its extremely small 0201 package makes it ideal for high-density PCB layouts in space-constrained designs. Engineered for low resistance, stable performance, and long service life, this device is well-suited for consumer electronics, IoT modules, and portable applications requiring efficient and reusable circuit protection.
