0ZRR0030FF2E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRR0030FF2E is a radial leaded PPTC resettable fuse from the 0ZRR series. It features a hold current of 300 mA and a trip current of 600 mA at ambient conditions. The device supports a maximum voltage of 60 VDC with a maximum fault current rating of 40 A. Its initial resistance is 2.1 mOhms, and it operates within a temperature range of -40°C to +85°C. Physical dimensions include 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 circuit protection through positive temperature coefficient polymer technology that increases resistance during overcurrent events.
• Offers reusable functionality by resetting to low resistance once the fault condition is removed and the component cools down.
• Designed for slow-blow response characteristics to tolerate temporary inrush currents without nuisance tripping.

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection circuits in automotive electronics systems
• Battery pack management and safeguarding

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF2E confirms the reel packaging format required for automated assembly processes. Confirm that the 300 mA hold current aligns with the target circuit's normal operating load to prevent unintended activation. Ensure the 60 VDC maximum voltage rating exceeds the system's peak operating voltage under all conditions. Validate that the physical footprint fits the designated PCB layout constraints.

Ptc Resettable Fuses Selection Notes

Select this component when a radial leaded form factor is preferred over surface mount alternatives for mechanical stability or ease of manual insertion. Choose based on the 300 mA hold current requirement and the need for a 60 VDC rating. Consider the 2.1 mOhms resistance for minimal power loss in low-voltage applications. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +85°C range.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRR series of radial PPTC resettable fuses. The series provides cost-effective overcurrent protection solutions for various consumer and industrial applications. The 0ZRR designation indicates a standard radial leaded construction suitable for through-hole mounting technologies.

Ptc Resettable Fuses Replacement Considerations

The 0ZRR0030FF1E offers identical electrical specifications but utilizes bulk packaging instead of reels. Verify that the packaging difference does not impact the manufacturing workflow or component handling requirements.
