0ZRG0075FF2E

Ptc Resettable Fuses Overview

The Bel Fuse Inc. 0ZRG0075FF2E is a polymer PTC resettable fuse designed for surface mount applications in the 0402 (1005 metric) package. It features a maximum voltage rating of 30 VDC and a hold current of 750 mA. The device trips at 1.3 A with a maximum initial resistance of 230 mOhms and a post-trip resistance of 600 Ohms. It supports a maximum fault current of 40 A and operates within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Provides overcurrent protection through automatic resistance increase upon fault detection
• Designed for low-profile surface mount integration on printed circuit boards
• Complies with automotive reliability standards including AEC-Q200 certification

Ptc Resettable Fuses Applications

• Automotive electronic module protection
• Portable consumer device circuit safeguarding
• Industrial control system component protection

Ptc Resettable Fuses Procurement Notes

Verify the specific package dimensions against the official datasheet to ensure compatibility with the target footprint, as surface mount variants require precise alignment. Confirm that the operating voltage does not exceed the 30 VDC limit during normal operation. Check for RoHS compliance status relevant to the destination market regulations before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when space constraints necessitate a small surface mount form factor while requiring 750 mA continuous current handling. Ensure the application voltage remains below 30 VDC to maintain safety margins. Consider the trip current threshold of 1.3 A to avoid nuisance tripping during normal transient load spikes in the target circuit design.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRG series of low-current polymer PTC resettable fuses from Bel Fuse. The series focuses on compact protection solutions for modern electronics where board real estate is limited. It complements larger SMD and through-hole options by providing reliable circuit interruption in minimal physical volume.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other 0ZRG series variants or 0ZCK models if higher voltage ratings are required. Verify that substitute parts match the 0402 package outline and 750 mA hold current specifications to maintain electrical performance equivalence.
