0ZRP0090FF2B

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRP0090FF2B is a polymeric PTC resettable fuse rated for 60 VDC maximum voltage and 900 mA hold current. It features a trip current of 1.8 A and a maximum fault current rating of 40 A. The device exhibits a typical resistance of 520 Ohms and operates within a temperature range of -40°C to +85°C. Designed with radial through-hole leads spaced at 5.10 mm, it complies with AEC-Q200 standards and provides slow-blow protection characteristics.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection via self-resetting polymeric positive temperature coefficient technology
• Complies with AEC-Q200 automotive qualification standards for reliability
• Features radial leaded package suitable for through-hole mounting applications

Ptc Resettable Fuses Applications

• Automotive electronic circuits requiring AEC-Q200 compliance
• Overcurrent protection in low-voltage DC power lines
• Protection of sensitive components in consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF2B corresponds to the radial through-hole package configuration rather than bulk or reel variants. Confirm that the AEC-Q200 qualification status meets project requirements. Ensure the 60VDC rating aligns with the system's maximum operating voltage. Check lead spacing compatibility with the target PCB footprint before finalizing procurement.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable fuse with AEC-Q200 certification is required for automotive or high-reliability applications. The 900mA hold current suits moderate load protection needs. The 60VDC rating limits suitability to low-voltage systems. Consider the 520 Ohm resistance impact on signal integrity if used in sensitive data lines. The radial form factor dictates PCB layout constraints compared to surface-mount alternatives.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRP series of polymeric PTC resettable fuses. The series offers various hold currents and voltage ratings tailored for different protection scenarios. The 0ZRP designation indicates a standard radial leaded construction. This specific model represents a mid-range current option within the family, balancing protection sensitivity with fault handling capacity.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 0ZRP series parts with matching 900mA hold current and 60VDC rating. Verify lead spacing and physical dimensions for mechanical fit. Alternative manufacturers may offer equivalent PTC devices but require validation of AEC-Q200 compliance if mandated by the design.
