CMF-SDP50-2 Description

Short technical summary and product information.

The Bourns CMF-SDP50-2 is a ceramic PTC resettable fuse designed for telecom overcurrent protection. It features a hold current of 90mA and a trip current of 190mA, with a rated voltage of 230V and an induction withstand voltage of 600V. The device offers an initial resistance of 50Ω with ±15% tolerance and resistance matching within 1.0Ω between the two PTC elements in the housing.

 

This component is housed in a compact 4-SMD Cube package measuring 11.00mm x 9.00mm with a maximum thickness of 11.50mm, suitable for surface mount assembly. It operates over a temperature range of -40°C to 125°C and is rated MSL Level 1 for moisture sensitivity. The part is RoHS compliant and carries an ESD classification of Class 6 (HBM).

 

Typical applications include secondary overcurrent protection in customer premise equipment (CPE), central office (CO) equipment, and access equipment. The matched resistance pair ensures balanced performance in telecom line protection circuits.
