0ZRB0135FF1E

Ptc Resettable Fuses Overview

The 0ZRB0135FF1E is a radial leaded polymeric positive temperature coefficient (PPTC) resettable fuse from the Bel Fuse 0ZRB series. It features a hold current of 1.35 A and a trip current of 2.7 A, designed for circuits operating at a maximum voltage of 30 VDC. The device has a typical resistance of 300 milliohms and a high fault current rating of 40 A. It operates within a temperature range of -40°C to +85°C and utilizes a slow-blow response characteristic.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection by increasing resistance in response to overcurrent conditions
• Restores normal operation after cooling without requiring manual replacement
• Designed with radial leads for through-hole mounting on printed circuit boards

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection of battery packs and charging circuits
• Surge protection in telecommunications equipment
• Circuit safeguarding in consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify that the application voltage does not exceed the 30 VDC maximum rating to ensure reliable operation. Confirm that the expected hold current remains below 1.35 A under all operating conditions. Check ambient temperature limits against the specified -40°C to +85°C range. Ensure the physical footprint matches the radial lead configuration required by the design.

Ptc Resettable Fuses Selection Notes

Select this component when a low-voltage, moderate-current protection solution is required. Compare the 1.35 A hold current against the circuit's normal operating current to prevent nuisance tripping. Consider the 300 milliohm resistance impact on power loss. Evaluate the 40 A fault current capability against potential short-circuit scenarios in the target application.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRB series of PTC resettable fuses manufactured by Bel Fuse Inc. The series offers various hold current options for different voltage ratings. The 0ZRB designation indicates a specific family of radial leaded devices optimized for cost-effective overcurrent protection in compact electronic assemblies.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 1.35 A hold current, 30 VDC rating, and radial package. Verify equivalent trip current and resistance values. Cross-reference with other manufacturers' PPTC components having identical electrical specifications and thermal characteristics.
