0ZRB0185FF2E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRB0185FF2E is a polymeric PTC resettable fuse designed for surface mount applications. It features a hold current of 1.85 A and a maximum voltage rating of 30 VDC. The device trips at a current of 3.7 A and exhibits an initial resistance of 150 Ohms. Packaged in a radial disc form factor, it measures 7.4 mm in diameter and 3.1 mm in height. The component operates within a temperature range of -40°C to +85°C and supports a maximum fault current of 100 A.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection through self-resetting functionality upon fault clearance.
• Utilizes polymeric positive temperature coefficient material for reliable thermal response.
• Designed for through-hole radial mounting on printed circuit boards.

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection circuits in automotive electronics
• Industrial control system power lines

Ptc Resettable Fuses Procurement Notes

Verify the specific package configuration and lead times with authorized distributors prior to ordering. Confirm that the radial disc form factor aligns with the target PCB footprint requirements. Ensure compliance with RoHS directives if required by the end product specifications. Cross-reference datasheet parameters against application load conditions to guarantee adequate safety margins during operation.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile radial fuse is required for circuits operating up to 30 VDC. The 1.85 A hold current suits moderate power applications needing resettable protection. Consider the 150 Ohm initial resistance impact on signal integrity or power loss. Evaluate the 100 A maximum fault current capability against potential short-circuit scenarios in the design.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRB series of polymeric PTC resettable fuses. The series offers various hold current ratings and voltage options tailored for different circuit protection needs. The 0ZRB designation specifically indicates a radial disc package style, distinguishing it from surface mount chip variants within the broader product portfolio.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other Bel Fuse radial PTC fuses with matching electrical ratings, such as the 0ZRB0185FF1E if packaging differences are acceptable. Verify that any replacement maintains the 30 VDC voltage rating and 1.85 A hold current to ensure circuit compatibility.
