0ZAF0005FF28

Overview

The Bel Fuse Inc. 0ZAF0005FF28 is a polymeric PTC resettable fuse designed for surface mount applications. It belongs to the 0ZAF series and features a 2920 (7351 metric) package with a concave profile. The device maintains a holding current of 50 mA and trips at 120 mA. It supports a maximum voltage of 240 VAC (250 VDC) and has a maximum trip time of 15 seconds. The component operates within a temperature range of -40°C to +85°C.

Feature Summary

Surface mountable solid-state protection against overcurrent, short circuits, and over-temperature conditions
Faster time to trip compared to standard SMD devices
Full compliance with EU Directive 2011/65/EU

Applications

Protection against harmful overcurrent conditions
Short circuit protection in electronic circuits
Over-temperature condition mitigation

Procurement Notes

Verify the specific package variant, as the 0ZAF series includes both standard and concave profiles. Confirm that the 240VAC rating aligns with your system's voltage requirements. Ensure the 50mA holding current meets the operational load needs without nuisance tripping. Check for RoHS compliance documentation if required by your manufacturing standards. Validate the 15-second trip time specification against your fault response requirements.

Selection Notes

Select this component when surface mount space is limited to the 2920 footprint. Choose this part for applications requiring faster response times than standard SMD PTCs. Ensure the 240VAC rating is sufficient for the circuit being protected. Verify that the 50mA holding current is appropriate for the normal operating current. Consider the concave profile if board clearance or specific mounting constraints are present.

Part Context

This component is part of the Bel Fuse 0ZAF series, which focuses on high-performance surface mount PTC fuses. The series is engineered for compact electronics where rapid fault detection is critical. It complements other Bel Fuse offerings like the 0ZCF and 0ZCH series, providing specialized solutions for different current and voltage ratings within the same form factor family.
