0ZCA0020FF2E

Overview

The Bel Fuse 0ZCA0020FF2E is a surface-mount polymeric PTC resettable fuse designed for overcurrent protection in electronic circuits. It features a hold current of 200 mA and a trip current of 400 mA, ensuring reliable operation under normal conditions while responding to faults. The device supports a maximum voltage of 30 VDC and exhibits a typical resistance of 600 mOhms. Housed in a compact 1206 (3216 metric) package, it operates within a temperature range of -40°C to +85°C. This slow-blow component provides effective circuit safeguarding with minimal footprint requirements.

Feature Summary

• Polymeric positive temperature coefficient construction enables automatic reset functionality after fault clearance
• Surface mount design facilitates automated assembly and integration into compact printed circuit boards
• Slow blow characteristic accommodates temporary inrush currents without nuisance tripping during normal operation

Applications

• Overcurrent protection for portable electronic devices
• Circuit safeguarding in consumer electronics assemblies
• Protection of data lines and peripheral interfaces
• Battery pack management systems

Procurement Notes

Verify the specific ordering suffix matches the required hold current and voltage ratings for the target application. Confirm that the 1206 package dimensions align with the designated PCB footprint and solder mask specifications. Ensure compliance with RoHS directives if required by the manufacturing facility. Check moisture sensitivity levels to determine appropriate storage and reflow profile adherence during production.

Selection Notes

Select this component when a low-profile surface mount solution is required for moderate current protection. The 200 mA hold current suits applications with steady-state loads near this threshold. Consider the 30 VDC rating to ensure compatibility with the system's operating voltage. Evaluate the thermal environment to confirm the +85°C maximum operating temperature meets the design constraints.

Part Context

This part belongs to the 0ZCA series of polymeric resettable fuses from Bel Fuse. It serves as a reusable alternative to traditional one-time fuses, offering cost-effective protection against overcurrent events. The series is engineered for high reliability in space-constrained environments, providing consistent performance across various industrial and consumer applications.

Replacement Considerations

The 0ZCJ0020FF2E is a confirmed substitute within the same manufacturer lineup, sharing identical electrical parameters and the 1206 package form factor. Verify that any replacement maintains the same voltage rating and hold current specifications to ensure circuit compatibility.
