Overview
The 0ZCB0175FF2E is a polymeric PTC resettable fuse manufactured by Bel Fuse Inc. It features a hold current of 1.75 A and a trip current of 3.5 A, with a maximum voltage rating of 6 VDC. The device has a maximum current rating of 100 A and an initial resistance of 150 Ohms. It utilizes a 1210 (3225 metric) surface mount package with concave terminals. The component operates within a temperature range of -40°C to +85°C.
Feature Summary
- Polymeric positive temperature coefficient construction for overcurrent protection
- Surface mount design with concave termination style for PCB mounting
- Self-resetting functionality upon cooling after fault condition removal
Applications
- Portable electronic devices requiring compact circuit protection
- Consumer electronics with low-voltage DC power inputs
- Battery-powered equipment needing overcurrent safeguarding
Procurement Notes
Verify the specific suffix 'FF2E' against official Bel Fuse documentation to confirm terminal configuration and packaging details. Ensure compatibility with automated surface mount assembly processes. Confirm moisture sensitivity levels and reflow soldering profiles prior to integration into production lines.
Selection Notes
Select this component when a low-profile surface mount solution is required for circuits operating at 6 VDC or less. The 1.75 A hold current suits applications demanding precise current limiting without nuisance tripping during normal operation. Consider the 1210 footprint constraints and thermal management requirements for the target environment.
Part Context
This part belongs to the 0ZCB series of surface mount PTC resettable fuses from Bel Fuse. The series offers various hold currents and voltage ratings tailored for space-constrained electronic designs. The 0ZCB series is designed for high-volume manufacturing environments requiring reliable overcurrent protection in consumer and industrial applications.
Replacement Considerations
Consult official Bel Fuse substitution guides for verified equivalents. Cross-reference parameters such as hold current, trip current, voltage rating, and package dimensions to ensure functional compatibility.
