PTR016V1100-BK1

Ptc Resettable Fuses Overview

The Eaton Electronics Division PTR016V1100-BK1 is a polymeric positive temperature coefficient (PPTC) resettable fuse designed for circuit protection. It features a radial leaded package suitable for PCB mounting. The device maintains a hold current of 1.1 A and trips at 2.2 A under fault conditions. It supports a maximum voltage of 16 V DC and withstands up to 40 A fault current. The component exhibits a typical resistance of 95 mΩ and operates within a temperature range of -40°C to +85°C. Lead spacing is standardized at 5 mm, with physical dimensions including a height of 14.2 mm.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit interruption upon overheating due to overcurrent events
• Restores normal conductivity after cooling down without manual replacement
• Offers reliable protection against short circuits and excessive current loads

Ptc Resettable Fuses Applications

• Overcurrent protection in low-voltage electronic circuits

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix BK1 against official Eaton documentation to confirm packaging configuration and lead form variations. Ensure compatibility with peak pulse currents and ambient operating temperatures specified in the datasheet. Cross-reference manufacturer part numbers directly to avoid substitution errors with similar series components.

Ptc Resettable Fuses Selection Notes

Select this component based on the required hold current of 1.1 A and maximum system voltage of 16 V. Evaluate the trip current threshold of 2.2 A against expected transient loads. Confirm that the radial through-hole mounting style fits the printed circuit board layout constraints and thermal dissipation requirements.

Ptc Resettable Fuses Part Context

This part belongs to the PolyTron PTC device family from Eaton Electronics Division. These resettable fuses serve as alternative protection devices to traditional one-time fuses. The series is engineered for compact electronic applications requiring reusable overcurrent protection solutions.

Ptc Resettable Fuses Replacement Considerations

Consult official Eaton cross-reference guides for verified substitutes. Generic PPTC replacements may differ in response time or mechanical dimensions.
