0ZRS0070FF2D

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRS0070FF2D is a radial leaded PPTC resettable fuse from the 0ZRS series, designed for PCB mounting. It features a 700 mA hold current and a 1.4 A trip current, with a maximum voltage rating of 32 VDC. The device has an initial resistance of 800 mOhms and a maximum interrupting rating of 100 A. It operates within a temperature range of -40°C to +125°C and holds AEC-Q200 qualification. The component measures 3 mm in height and is supplied in a reel package.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection through self-resetting polymeric positive temperature coefficient technology.
• Meets automotive reliability standards via AEC-Q200 qualification for use in vehicle electronics.
• Features radial leads for straightforward through-hole PCB integration.

Ptc Resettable Fuses Applications

• Automotive electronic circuits requiring AEC-Q200 compliance
• Overcurrent protection for low-voltage DC power lines
• PCB-mounted circuit safeguarding in harsh thermal environments

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF2D against official manufacturer documentation to confirm the tape and reel packaging configuration. Ensure that the 32 VDC voltage rating and 700 mA hold current align precisely with the target circuit requirements before procurement. Confirm AEC-Q200 certification status is required for the intended application.

Ptc Resettable Fuses Selection Notes

Select this component when a radial leaded form factor is necessary for PCB assembly rather than surface mount alternatives. Consider the 800 mOhms initial resistance for potential voltage drop impacts in sensitive low-voltage designs. Evaluate the 100 A interrupting rating to ensure adequate safety margins against fault currents in the specific application environment.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRS series of resettable fuses manufactured by Bel Fuse. The series utilizes polymeric positive temperature coefficient materials to provide reusable overcurrent protection. These devices are engineered to automatically restore conductivity after cooling down following a fault condition, offering a maintenance-free alternative to traditional one-time fuses.

Ptc Resettable Fuses Replacement Considerations

Cross-reference other 0ZRS series variants with matching 700 mA hold current and radial lead specifications. Verify that any substitute maintains the same 32 VDC maximum voltage rating and AEC-Q200 qualification level to ensure compatibility with existing automotive design constraints.
