0ZCF0300AF2C

Ptc Resettable Fuses Overview

The 0ZCF0300AF2C is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the Bel Fuse 0ZCF series. It provides overcurrent protection in a compact 2920 (7450 metric) package with dimensions of 7.35 mm length, 5.12 mm width, and 1.05 mm height. The device maintains a holding current of 3 A and trips at 5.2 A, operating within a maximum voltage rating of 15 VDC. Initial resistance is specified at 48 Ohms. It functions as a slow-blow fuse across an operating temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Polymeric PPTC technology enables automatic circuit restoration after fault clearance without manual replacement.
• Slow-blow response characteristic accommodates temporary inrush currents while protecting against sustained overloads.
• Surface-mount construction facilitates automated assembly on printed circuit boards.

Ptc Resettable Fuses Applications

• Portable electronic devices requiring compact overcurrent protection
• Laptop and notebook computer peripheral interfaces
• Consumer electronics power input circuits

Ptc Resettable Fuses Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm RoHS compliance status via official certification documents prior to integration. Ensure storage conditions account for moisture sensitivity classification to prevent package degradation during handling and soldering processes.

Ptc Resettable Fuses Selection Notes

Select this component when circuit design requires a 3 A holding current with a 15 VDC maximum rating. The 2920 package size suits applications with limited board space constraints. Evaluate thermal management requirements to ensure ambient temperatures remain within the -40°C to +85°C operational window for reliable performance.
