0ZRR0025FF2E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRR0025FF2E is a radial leaded polymeric positive temperature coefficient (PPTC) resettable fuse designed for circuit protection. It features a hold current of 250 mA and a trip current of 500 mA, operating within a voltage range up to 60 VDC. The device exhibits a low initial resistance of 3 mOhms and can withstand fault currents up to 40 A maximum. It is rated for an ambient operating temperature range from -40°C to +85°C. The component has a cylindrical body with a diameter of 7.4 mm and a height of 3.1 mm. It is supplied in reel packaging.

Ptc Resettable Fuses Feature Summary

• Provides automatic resettable overcurrent protection through self-heating polymer technology.
• Offers high fault current interruption capability up to 40 A maximum rating.
• Features low on-resistance to minimize power loss during normal operation.
• Designed for slow-blow response characteristics to tolerate temporary inrush currents.

Ptc Resettable Fuses Applications

• Protection of portable electronic devices against overcurrent conditions
• Circuit safeguarding in automotive electronics applications
• Overcurrent protection for telecommunications equipment interfaces
• Battery pack protection in consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix '2E' corresponds to the required reel packaging configuration when ordering. Confirm that the 250 mA hold current aligns with the target circuit's continuous operational requirements. Ensure the 60 VDC maximum voltage rating exceeds the system's peak operating voltage. Check RoHS compliance documentation if environmental regulations apply to the final assembly. Validate that the radial leaded form factor fits the designated PCB footprint constraints.

Ptc Resettable Fuses Selection Notes

Select this component when a radial leaded PPTC device is preferred over surface mount alternatives for mechanical stability or automated insertion processes. The 250 mA hold current makes it suitable for low-power signal lines or small sensor circuits. Consider the 3 mOhms resistance value for applications sensitive to voltage drop. The 60 VDC rating provides adequate margin for standard low-voltage DC systems. Evaluate the thermal environment to ensure the +85°C maximum rating accommodates ambient temperatures without derating issues.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRR series of radial leaded resettable fuses. The series offers various hold current options ranging from low milliampere values to higher amperage ratings. All devices in this family share similar physical dimensions and voltage ratings, differing primarily in their current tripping characteristics. The 0ZRR series is widely used in general-purpose circuit protection where manual fuse replacement is undesirable.
