Overview
The 0ZCA0075FF2G is a polymeric PTC resettable fuse manufactured by Bel Fuse Inc. It features a maximum voltage rating of 6V and a hold current (Ih) of 750 mA. The trip current (It) is specified at 1.5 A, with a maximum fault current capacity of 40 A. The device utilizes an SMD package in the 1206 (3216 Metric) concave form factor. Initial resistance (Ri) has a minimum value of 90 mOhms, while post-trip resistance (R1) has a maximum value of 350 mOhms. It operates within a temperature range of -40°C to +85°C and holds AEC-Q200 automotive qualification.
Feature Summary
- Polymer PTC technology providing automatic reset capability after fault conditions clear
- Automotive-grade reliability certified under AEC-Q200 standards
- Low-profile surface mount design suitable for space-constrained PCB layouts
Applications
- Overcurrent protection for automotive electronic modules
- Protection circuits for portable consumer electronics
- Battery pack safeguarding in mobile devices
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the received parts match the specific 0ZCA0075FF2G designation and packaging format. Check for moisture sensitivity level compliance prior to soldering. Ensure storage conditions maintain integrity before assembly into final products.
Selection Notes
Select this component when a low-voltage circuit requires overcurrent protection with rapid response characteristics. The 750 mA hold current suits applications with steady-state currents below this threshold. The 6V rating limits usage to low-voltage DC systems. Consider the 1206 footprint constraints during PCB layout planning to ensure adequate thermal dissipation and mechanical stability.
Part Context
This part belongs to the 0ZCA series of surface mount PTC resettable fuses from Bel Fuse. It complements other variants in the lineup offering different current ratings and voltage specifications. The series targets compact electronic designs requiring reliable circuit protection without manual intervention after fault clearance.
Replacement Considerations
Direct substitutes include 0ZCK0075FF2E and 0ZCG0075FF2C, though package dimensions differ. Verify electrical parameters such as hold current and voltage ratings match system requirements before substitution. Cross-reference datasheets for thermal performance and physical mounting compatibility.
