0ZRS0750FF1A

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRS0750FF1A is a radial leaded PPTC resettable fuse designed for automotive applications, certified to AEC-Q200 standards. It features a 7.5 A hold current and a 32 VDC maximum voltage rating. The device trips at 15 A with a maximum fault current of 100 A. Initial resistance is 23 mOhms, and power dissipation is 6.5 W. Operating temperature ranges from -40°C to +125°C. Dimensions are 24.9 mm length, 21.1 mm width, and 3.8 mm height.

Ptc Resettable Fuses Feature Summary

• Automotive-grade reliability verified by AEC-Q200 qualification.
• Self-resetting protection mechanism utilizing positive temperature coefficient polymer technology.
• Radial leaded construction facilitates through-hole PCB mounting.

Ptc Resettable Fuses Applications

• Automotive electronic circuit overcurrent protection
• Battery pack management systems
• Vehicle infotainment and control module circuits

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF1A corresponds to the bulk packaging format required for assembly. Confirm that the 32 VDC voltage rating aligns with the target circuit's operating parameters. Ensure the 7.5 A hold current meets the continuous load requirements without nuisance tripping during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when automotive certification is mandatory and low on-resistance is critical for efficiency. The high trip current of 15 A allows tolerance for transient surges. Compare against other 0ZRS variants if higher voltage ratings or different current thresholds are needed for the specific application design.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRS series of radial PPTC devices. It shares the AEC-Q200 qualification family but differs in electrical ratings from other members like the 0ZRS0200FF1E or 0ZRS0070FF2D. The series provides a standardized footprint solution for automotive PCB layouts requiring resettable protection.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes within the same series include 0ZRS0200FF1E (2A) or 0ZRS0070FF2D (700mA) if current ratings can be adjusted. Cross-series replacements require verifying AEC-Q200 compliance and matching thermal characteristics.
