Overview
The Bel Fuse Inc. 0ZCC0014FF2C is a polymer PTC resettable fuse from the 0ZCC series, designed for surface-mount applications in the 1812 (4532 metric) package. It features a hold current of 140 mA and a trip current of 280 mA, with a maximum voltage rating of 8 VDC. The device exhibits an initial resistance of 210 mOhms and a maximum post-trip resistance of 1.5 Ohms. It supports a maximum fault current of 100 A and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Provides automatic circuit protection through reversible polymer positive temperature coefficient technology.
- Offers high fault current interruption capability up to 100 A for robust system safety.
- Features low initial resistance to minimize power loss during normal operation.
Applications
- Overcurrent protection for portable electronic devices
- Protection circuits in automotive electronics systems
- Power supply input protection for consumer appliances
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package dimensions and electrical parameters match the 1812 form factor. Ensure storage conditions comply with moisture sensitivity level requirements to prevent soldering defects during assembly.
Selection Notes
Select this component when designing low-voltage circuits requiring compact overcurrent protection. Ensure the operating voltage does not exceed 8 VDC and the continuous load current remains below 140 mA. Consider thermal derating requirements based on ambient temperature conditions exceeding standard ratings.
Part Context
This part belongs to the 0ZCC series of polymer PTC resettable fuses manufactured by Bel Fuse Inc. The series is characterized by its small surface-mount footprint and suitability for space-constrained designs. It serves as a reusable alternative to traditional one-time fuses in modern electronic assemblies.
Replacement Considerations
Direct substitute: PTS181208V014 Eaton - Electronics Division. Verify that the replacement maintains equivalent voltage, current, and package specifications before integration into existing designs.
