0ZCJ0110FF2E

Ptc Resettable Fuses Overview

The 0ZCJ0110FF2E is a surface-mount polymer PTC resettable fuse from the Bel Fuse 0ZCJ series, designed for circuit protection in low-voltage applications. It features a 1206 (3216 metric) package with a hold current of 110 mA and a trip current of 220 mA. The device supports a maximum voltage of 6V DC and offers a maximum fault current rating of 100 A. Initial resistance is typically 55 mOhms, rising to a maximum of 210 mOhms after tripping. It operates within a temperature range of -40°C to +85°C and holds AEC-Q200 automotive qualification.

Ptc Resettable Fuses Feature Summary

• Polymer PTC technology provides automatic reset functionality after fault clearance without manual intervention.
• AEC-Q200 qualified for reliable performance in demanding automotive electronic environments.
• Low-profile 1206 SMD package enables efficient space utilization on high-density printed circuit boards.

Ptc Resettable Fuses Applications

• Automotive infotainment and display system power line protection
• USB port overcurrent protection in consumer electronics
• Battery pack protection circuits for portable devices

Ptc Resettable Fuses Procurement Notes

Verify that the specific order suffix matches the required voltage and current ratings, as variations exist within the 0ZCJ family. Confirm moisture sensitivity level handling procedures are followed during assembly to ensure device integrity. Cross-reference the manufacturer's latest datasheet for any updates to certification status or recommended soldering profiles before finalizing procurement specifications.

Ptc Resettable Fuses Selection Notes

Select this component when a low operating voltage of 6V DC is required, distinguishing it from higher-voltage variants like the 0ZCJ0010FF2E rated at 60V. Ensure the application current does not exceed the 110 mA hold current under normal conditions. Consider the 1206 footprint constraints and verify that the 100 A interrupt rating aligns with the available short-circuit current in the target circuit design.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZCJ series of low-voltage, surface-mount PPTC fuses manufactured by Bel Fuse Inc. The series is characterized by its compact 1206 package size and suitability for automotive and industrial applications requiring AEC-Q200 compliance. It complements other series such as 0ZCA and 0ZCG which offer different voltage ratings and package dimensions.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include the 0ZCJ0100FF2E, which shares the same 1206 package and 6V rating but has a slightly lower hold current of 100 mA. Verify that the alternative part meets the specific 110 mA hold current requirement of the original design to prevent nuisance tripping.
