PTR060V0185-BK1

Ptc Resettable Fuses Overview

The Eaton PTR060V0185-BK1 is a polymer PTC resettable fuse from the PTR060V series, designed for through-hole PCB mounting. It features radial kinked leads with a 5 mm spacing and operates within a temperature range of -40°C to +85°C. The device maintains a maximum voltage of 60 VDC and a hold current of 1.85 A, with a trip current of 3.7 A. Its initial resistance is typically 80 mOhms minimum, rising to a maximum post-trip resistance of 190 mOhms. The component supports a maximum fault current of 40 A and carries cURus and TUV certifications.

Ptc Resettable Fuses Feature Summary

• Provides automatic overcurrent protection by increasing resistance during fault conditions
• Features self-resetting capability upon cooling after fault removal
• Includes radial kinked leads for secure through-hole PCB installation

Ptc Resettable Fuses Applications

• Overcurrent protection in consumer electronics circuits
• Protection for portable computing devices and peripherals
• Circuit safeguarding in industrial control systems

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix BK1 corresponds to the bulk packaging configuration as documented in official Eaton datasheets. Confirm that the lead form matches the radial kinked specification required for your assembly process. Ensure compatibility with the 60V maximum voltage rating for your target application circuitry before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a 1.85 A hold current and 60 V maximum voltage rating are required for through-hole applications. Consider the 80 mOhms minimum initial resistance for low-power loss requirements. Verify that the 40 A maximum fault current rating exceeds the prospective short-circuit current of the protected circuit to ensure adequate safety margins.

Ptc Resettable Fuses Part Context

This part belongs to the Eaton PTR060V series of polymer PTC resettable fuses. The series offers various hold current options within a 60 VDC system. The PTR060V0185-BK1 specifically addresses the 1.85 A requirement with radial kinked leads, distinguishing it from tape-and-reel variants like the PTR060V0185-TR.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other 60V 1.85A radial PTC fuses if supply constraints exist. Verify that substitute components match the 190 mOhms maximum post-trip resistance and 40 A maximum fault current ratings to maintain equivalent circuit protection performance.
