PTR030V0160-BK1

Ptc Resettable Fuses Overview

The Eaton PTR030V0160-BK1 is a PolyTron PTC resettable fuse designed for circuit protection. It features a maximum voltage of 30 V and a hold current of 1.6 A. The device trips at 3.2 A and withstands a maximum fault current of 40 A. Its initial resistance is 150 mOhms. Operating temperature ranges from -40 C to +85 C. It utilizes radial kinked leads with a 5 mm spacing for PCB mounting.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection through positive temperature coefficient polymer technology
• Offers reusable functionality by resetting after fault conditions clear
• Features radial kinked leads for secure through-hole PCB mounting

Ptc Resettable Fuses Applications

• Overcurrent protection in portable electronic devices
• Circuit safeguarding in automotive electronics
• Protection for communication equipment interfaces
• Battery pack overcurrent defense systems

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix BK1 corresponds to the required lead configuration and packaging format. Confirm that the 30 VDC rating aligns with the target circuit's maximum operating voltage. Ensure the 1.6 A hold current meets the normal operational load requirements without nuisance tripping during standard usage cycles.

Ptc Resettable Fuses Selection Notes

Select this component when a 30 VDC system requires a 1.6 A continuous current capacity. The 150 mOhms impedance is suitable for low-power signal lines. Consider the 40 A trip current limit for short-circuit scenarios. Verify thermal derating requirements if ambient temperatures exceed standard limits within the application enclosure.

Ptc Resettable Fuses Part Context

This part belongs to the PolyTron PTR series of resettable fuses from Eaton Electronics. The series provides reliable overcurrent protection across various voltage and current ratings. The PTR030V designation indicates the 30 Volt maximum working voltage class within the product family.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other Eaton PolyTron parts sharing identical 30 V, 1.6 A, and radial kinked lead specifications. Verify mechanical footprint compatibility before substitution. Ensure equivalent trip characteristics and thermal performance match the original design requirements.
