CMF-RL25U-0

Ptc Resettable Fuses Overview

The CMF-RL25U-0 is a radial leaded Positive Temperature Coefficient (PTC) resettable fuse from Bourns' CMF-RL series. It features a hold current of 60 mA and a trip current of 150 mA, with a maximum voltage rating of 220 VAC. The device exhibits a response time of 0.25 seconds at the trip current. Physically, it utilizes a round ceramic package measuring 5.2 mm in diameter by 3.5 mm in height. This component is designed for overcurrent protection applications where self-resetting functionality is required.

Ptc Resettable Fuses Feature Summary

• Self-resetting overcurrent protection utilizing Positive Temperature Coefficient technology
• Ceramic radial leaded construction suitable for telecommunications equipment
• Resistance increases as temperature rises to limit fault current

Ptc Resettable Fuses Applications

• Secondary overcurrent protection in Customer Premise Equipment
• Telecommunications circuit protection
• Low-voltage power source and load protection

Ptc Resettable Fuses Procurement Notes

Verify the specific part number suffix against official Bourns documentation to ensure correct electrical ratings. Confirm that the radial lead configuration matches the target PCB layout requirements. Cross-reference the voltage and current specifications with the application's operational parameters to guarantee adequate protection margins. Ensure compliance with relevant safety standards for the intended end-use environment.

Ptc Resettable Fuses Selection Notes

Select this component when a self-resetting fuse is required for secondary protection in telecom or CPE applications. The radial lead form factor facilitates through-hole mounting. Consider the 60 mA hold current and 150 mA trip current thresholds relative to the normal operating current of the protected circuit. Evaluate the 220 VAC rating against the maximum circuit voltage to ensure safe operation under fault conditions.
