0ZRS0100FF2B

Ptc Resettable Fuses Overview

The 0ZRS0100FF2B is a radial leaded PPTC resettable fuse from the Bel Fuse 0ZRS series, designed for PCB mounting. It features a holding current of 1 A and a trip current of 1.9 A, with a maximum voltage rating of 32 VDC. The device has a maximum rated current of 100 A and an initial resistance of 450 mOhms. It operates within a temperature range of -40°C to +125°C and holds AEC-Q200 qualification.

Ptc Resettable Fuses Feature Summary

• Provides overcurrent protection through automatic reset functionality upon cooling after fault removal
• Complies with AEC-Q200 automotive electronic component qualification standards
• Utilizes polymer positive temperature coefficient technology for slow-blow response characteristics

Ptc Resettable Fuses Applications

• Automotive electronics circuits requiring AEC-Q200 compliance
• Low-voltage DC power distribution protection
• PCB-mounted circuit protection in automotive environments

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix FF2B corresponds to the required packaging configuration, as ordering suffixes may indicate variations in tape-and-reel specifications or bulk packaging quantities. Confirm that the 32 VDC rating aligns with the target application's maximum operating voltage to ensure proper device performance and safety margins during procurement.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile, radial leaded PTC fuse is needed for 32 VDC automotive applications. Ensure the 1 A holding current matches the circuit's normal operating load and that the 1.9 A trip current provides adequate margin against transient surges while protecting against sustained overloads.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRS series of resettable fuses, which are characterized by their compact radial leaded form factor suitable for surface mount or through-hole PCB integration. The series is specifically engineered for automotive-grade reliability, distinguishing it from general-purpose industrial PTC devices by its adherence to strict automotive qualification protocols.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 0ZRS series variants with matching 1 A holding current and 32 VDC ratings, such as 0ZRS0100FF1E, provided the packaging format (bulk vs. reel) meets assembly requirements. Cross-series replacement requires verifying thermal dissipation and physical footprint compatibility.
