CMF-SDP10-2 is a surface-mount dual-channel resettable PTC (Positive Temperature Coefficient) fuse designed for secondary overcurrent protection in telecommunications equipment. The device features two resistance-matched PTCs housed in a plastic package with a rated resistance of 10 Ohms and narrow ±20% resistance tolerance matching between channels. It operates at a rated voltage of 230 VAC with a hold current of =1.0 A at 25°C and a trip current of 0.180 A at 25°C, providing reliable protection with a typical trip time of 3.8 seconds at maximum current (1.0 A) under 230 VAC conditions. The component operates across a wide temperature range of -40°C to +125°C and is RoHS compliant, making it suitable for use in Customer Premise Equipment (CPE), Central Office (CO), and access equipment where resettable overcurrent protection is required.
