Overview
The Bel Fuse 0ZCB0005FF2E is a polymer PTC resettable fuse in the 0ZCB series, designed for surface mount applications. It features a 1210 (3225 metric) package with dimensions of 3.22mm x 2.58mm and a maximum thickness of 1.15mm. The component has a hold current of 50 mA, trip current of 150 mA, and a maximum voltage rating of 60V. Initial resistance is at least 3.6 Ohms, while post-trip resistance does not exceed 50 Ohms. It supports a maximum fault current of 10 A and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Utilizes polymer technology for self-resetting circuit protection capabilities
- Designed for surface mount installation in compact electronic assemblies
- Provides overcurrent protection through positive temperature coefficient response
Applications
- Consumer electronics circuit protection
- Portable device power line safeguarding
- General purpose overcurrent protection in low-voltage systems
Procurement Notes
This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources rather than direct factory orders. Confirm end-of-life status and check for valid replacement part numbers from the same manufacturer before proceeding with procurement planning.
Selection Notes
Engineers selecting this part must account for its higher initial resistance compared to modern low-resistance alternatives. The 1210 footprint requires specific PCB land pattern considerations. Due to the obsolete status, design-in activities should prioritize evaluating newer generation components that offer improved electrical characteristics and longer supply chain stability.
Part Context
The 0ZCB series represents an older generation of surface mount PTC fuses from Bel Fuse. This specific model utilizes a standard 1210 package size common in earlier SMT designs. The series was intended for general-purpose protection but has been superseded by newer product lines offering lower resistance and faster response times.
Replacement Considerations
Consult official Bel Fuse documentation for current equivalents. Potential substitutes may include newer series within the 0ZCH or 0ZRR families that maintain similar voltage ratings and package footprints while offering updated performance specifications.
