PTR030V0160-BK

Ptc Resettable Fuses Overview

The Eaton PTR030V0160-BK is a Polymeric PTC Resettable Fuse from the PolyTron series, designed for through-hole PCB mounting. It features radial leads with a disc package and a 5 mm lead spacing. The component operates within a temperature range of -40°C to +85°C. Key electrical specifications include a maximum voltage of 30 VDC, a hold current of 1.6 A, and a trip current of 3.2 A. It has a maximum fault current rating of 100 A and a typical resistance of 190 mOhms.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection by increasing resistance in response to overcurrent conditions
• Enables manual or automatic reset after fault clearance without component replacement
• Utilizes polymeric positive temperature coefficient material for reliable thermal switching

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Circuit safeguarding in automotive electronics systems
• Protection for industrial control board interfaces

Ptc Resettable Fuses Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Eaton Electronics Division before procurement. Confirm that the 30 VDC rating aligns with the target circuit's maximum operating voltage. Ensure the 1.6 A hold current meets the application's continuous load requirements without nuisance tripping during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when a 30 VDC rating is required instead of the standard 16 VDC variants in the PTR016V series. The 1.6 A hold current suits low-power signal lines or battery protection circuits. Consider the 190 mOhms resistance impact on voltage drop in sensitive applications compared to higher-current models.

Ptc Resettable Fuses Part Context

This device belongs to the PolyTron family of resettable fuses manufactured by Eaton Electronics Division. It serves as a reusable alternative to traditional one-time fusible links. The part number indicates a 30 VDC voltage class and a 1.6 A current rating within the radial leaded product line.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes within the same voltage and current class may be available from other manufacturers such as Bourns or Littelfuse. Cross-reference dimensions and lead spacing to ensure mechanical compatibility with existing PCB footprints.
