0ZCM0004FF2G

Ptc Resettable Fuses Overview

The 0ZCM0004FF2G is a polymeric PTC resettable fuse manufactured by Bel Fuse Inc. It features a surface-mount 0603 (1608 metric) concave package designed for circuit protection applications. The device has a maximum voltage rating of 24V and a hold current (Ih) of 40 mA. It exhibits a trip current of 80 mA with an initial resistance minimum of 5 Ohms and a maximum post-trip resistance of 15 Ohms. The component operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Ptc Resettable Fuses Feature Summary

• Compact 0603 surface-mount footprint with concave profile for low-profile assembly
• Fast trip time characteristics for rapid overcurrent response
• Low DCR resistance design to minimize power loss in normal operation
• Full compliance with EU Directive 2011/65/EU and amending directive 2015/863

Ptc Resettable Fuses Applications

• Portable electronic devices requiring compact circuit protection
• Data communication ports and interfaces
• Battery packs and power management circuits
• Consumer electronics with limited board space

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF2G against official Bel Fuse documentation to confirm package type, marking, and reel specifications. Ensure compatibility with automated placement equipment due to the concave package profile. Confirm moisture sensitivity level handling procedures prior to soldering. Cross-reference the datasheet for thermal derating curves relevant to your application environment.

Ptc Resettable Fuses Selection Notes

Select this component when a 0603 footprint is required with a 40 mA hold current and 24V maximum voltage rating. Consider the fast trip time and low resistance characteristics for sensitive downstream components. Evaluate the post-trip resistance limits to ensure they do not interfere with circuit functionality during fault conditions. Compare against other 0ZCM series variants if different current or voltage ratings are needed.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZCM series of SMT Low Profile PTC Resettable Fuses from Bel Fuse. The series is characterized by small chip sizes and fast response times. The 0603 size offers a balance between current handling capability and board space efficiency. This specific model targets applications needing reliable protection in tight spaces.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 0ZCM series parts with identical electrical ratings but different suffixes for packaging variations. Verify that any replacement maintains the same 0603 concave package dimensions and thermal characteristics. Check for equivalent certification approvals such as cURus and TUV.
