0ZCG0110CF2B

Ptc Resettable Fuses Overview

The Bel Fuse 0ZCG0110CF2B is a surface-mount polymeric PTC resettable fuse designed for circuit protection. It features an 1812 (4532 metric) package with dimensions of 4.55 mm length, 3.24 mm width, and 1.05 mm height. The device maintains a holding current of 1.1 A and trips at 2.2 A. It supports a maximum voltage of 33 VDC and offers a maximum fault current rating of 40 A. Initial resistance is typically low, ensuring minimal impact on normal operation.

Ptc Resettable Fuses Feature Summary

• Fast trip time response for rapid overcurrent protection
• Low DCR resistance to minimize power loss in the circuit
• RoHS compliant construction meeting EU Directive 2011/65/EU standards

Ptc Resettable Fuses Applications

• Portable electronic devices requiring compact protection
• Consumer electronics circuits needing surface-mount solutions
• Data communication equipment interfaces

Ptc Resettable Fuses Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging options such as cut tape or reel availability. Ensure storage conditions respect moisture sensitivity levels to prevent damage prior to soldering. Cross-reference datasheet revisions to confirm parameter stability.

Ptc Resettable Fuses Selection Notes

Select this component when space constraints require an 1812 footprint with a 1.1 A hold current. The 33 VDC rating suits low-voltage digital logic and peripheral protection. Consider the fast trip characteristic for sensitive loads. Evaluate thermal management requirements given the small package size and self-heating characteristics during trip events.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZCG series of polymer PTC resettable fuses from Bel Fuse. The series is characterized by its small chip size and fast tripping capabilities compared to standard slow-blow variants. It serves as a reusable alternative to traditional one-time fuses in modern PCB designs where space and reliability are critical factors.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 1812 PTC fuses with matching 1.1 A hold current and 33 VDC ratings. Verify that replacement parts maintain similar trip times and resistance values to ensure circuit performance parity. Check for equivalent mounting footprints and thermal characteristics.
