Overview
The Bel Fuse Inc. 0ZCB0020FF2E is a polymeric PTC resettable fuse designed for surface mount applications in the 1210 (3225 metric) package. It features a maximum holding current of 200 mA and a maximum trip current of 400 mA, with a rated voltage of 30 VDC. The device exhibits a minimum initial resistance of 600 mOhms and a maximum post-trip resistance of 5 Ohms. It operates within a temperature range of -40°C to +85°C and supports a maximum fault current of 10 A.
Feature Summary
- Polymer-based self-resetting circuit protection mechanism
- Surface mount construction optimized for automated assembly
- AEC-Q200 qualified for automotive reliability standards
Applications
- Automotive electronic circuit protection
- Portable consumer device overcurrent safeguarding
- Industrial control board circuit defense
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and REACH registration details prior to integration. Ensure storage conditions address moisture sensitivity classification requirements to maintain device integrity during handling and reflow processes.
Selection Notes
Select this component when a compact 1210 footprint is required for low-voltage DC circuits. The 200 mA holding current suits sensitive signal lines or power rails needing precise overload management. Verify that the 30 VDC rating aligns with system operating voltages and that the 10 A interrupt capacity exceeds potential fault currents.
Part Context
This part belongs to the 0ZCB series of polymer PTC resettable fuses from Bel Fuse Inc. The series provides reusable overcurrent protection as an alternative to traditional one-time fuses. The 0ZCB variant specifically targets higher current density applications within the 1210 package size compared to lower-rated counterparts.
Replacement Considerations
Direct substitutes include the Littelfuse 0805L020YR and 0805L050WR, as well as the Bourns MF-PSMF020X-2. These alternatives offer comparable electrical characteristics but may differ in physical dimensions or mounting specifications.
