CMF-RL50-10-0 Description

Short technical summary and product information.

The Bourns CMF-RL50-10-0 is a ceramic PTC resettable fuse designed for telecom overcurrent protection. It features a hold current of 65 mA and a trip current of 150 mA, with a rated voltage of 220V and a withstand voltage of 600V. The initial resistance is 50 Ω with ±10% tolerance, and the time to trip is 150 ms maximum.

 

This device is housed in a radial disc package with through-hole mounting and a lead spacing of 5.08 mm. It operates over a temperature range of -40°C to 125°C. The CMF-RL50-10-0 is RoHS3 compliant and aids compliance with telecom standards such as ITU-T K.20/21 and Telcordia GR-1089-CORE.

 

Typical applications include overcurrent protection in telecom equipment, central office switches, and customer premises equipment. The narrow resistance tolerance and resettable nature make it suitable for designs requiring reliable protection without fuse replacement.
