0ZRR0185FF1A

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRR0185FF1A is a polymeric PTC resettable fuse from the 0ZRR series, designed for through-hole radial mounting. It features a hold current of 1.85 A and a trip current of 3.7 A, with a maximum voltage rating of 60 VDC. The component has a maximum fault current rating of 40 A and an initial resistance of 190 Ohms. It operates within a temperature range of -40°C to +85°C and complies with EU Directive 2011/65/EU.

Ptc Resettable Fuses Feature Summary

• Polymeric PTC technology providing automatic circuit protection that resets after cooling
• Radial leaded disc package suitable for through-hole PCB mounting
• Compliant with EU Directive 2011/65/EU regarding restricted substances

Ptc Resettable Fuses Applications

• Overcurrent protection in low-voltage DC electronic circuits
• Solid-state device protection in consumer electronics
• Industrial control systems requiring resettable fuses up to 60VDC

Ptc Resettable Fuses Procurement Notes

Verify the specific datasheet version for the 0ZRR0185FF1A to confirm electrical tolerances and thermal characteristics. Ensure the procurement channel provides official documentation from Bel Fuse Inc. to validate compliance with RoHS and EU Directive 2011/65/EU requirements before integration into final products.

Ptc Resettable Fuses Selection Notes

Select this component when a radial, through-hole resettable fuse is required for circuits operating at 60 VDC or lower. The 1.85 A hold current makes it suitable for protecting loads drawing steady currents near this value. Consider the 40 A max fault current capability for short-circuit scenarios where standard fuses might fail.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRR series of polymeric PTC resettable fuses. The series is characterized by low hold currents and radial leaded construction, targeting applications where space-constrained through-hole mounting is necessary for overcurrent protection in solid-state devices.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other 0ZRR series parts having similar hold currents (e.g., 0ZRR0150FF1A or 0ZRR0200FF1A) if current ratings require adjustment. Verify that replacement components maintain the same 60 VDC voltage rating and radial package dimensions for board compatibility.
