Overview
The 0ZCB0110FF2E is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse manufactured by Bel Fuse Inc. It belongs to the 0ZCB series and features a 1210 (3225 Metric) concave package. The device has a holding current of 1.1 A, a maximum voltage rating of 6 VDC, and a trip current of 2.2 A. Its initial resistance is 210 Ohms. The component operates within a temperature range of -40°C to +85°C.
Feature Summary
- Polymeric PTC technology provides automatic circuit protection that resets after fault conditions clear.
- Concave package design facilitates reliable surface-mount assembly on printed circuit boards.
- Slow-blow characteristic allows tolerance for temporary inrush currents without nuisance tripping.
Applications
- Overcurrent protection for low-voltage electronic circuits
- Protection of portable consumer electronics powered by USB or similar low-voltage sources
- Battery pack protection in mobile devices
Procurement Notes
Verify the specific ordering suffix FF2E to ensure the correct package style and termination type are selected. Confirm RoHS compliance status through official documentation prior to integration. Check for availability as some distributors may list this part as obsolete with substitute options available.
Selection Notes
Select this component when a 6VDC system requires overcurrent protection with a 1.1A holding current. Ensure the PCB footprint matches the 1210 concave package dimensions. Consider the 210 Ohm initial resistance impact on signal integrity if used in sensitive lines. Verify ambient temperature derating requirements against the specified -40°C to +85°C operating range.
Part Context
This part is part of Bel Fuse's 0ZCB series of PTC resettable fuses. These components are designed for surface-mount applications requiring compact protection solutions. The series offers various current ratings and voltage options to suit different circuit requirements while maintaining a consistent form factor for design flexibility.
Replacement Considerations
DigiKey lists this product as obsolete. Official substitutes should be identified through the manufacturer's replacement guide or authorized distributor databases. Do not assume direct pin-to-pin compatibility with generic PTCs without verifying electrical parameters and package dimensions.
