PTR016V0090-BK

Ptc Resettable Fuses Overview

The Eaton PTR016V0090-BK is a PolyTron PTC resettable fuse designed for overcurrent protection in low-voltage circuits. It features a maximum voltage rating of 16 VDC and a hold current (Ih) of 0.9 A. The trip current (It) is specified at 1.8 A, ensuring reliable activation during fault conditions. The device has a maximum fault current rating of 40 A and an initial resistance of 120 mOhms. It utilizes radial kinked leads with a 5 mm spacing for through-hole PCB mounting. The component operates within a temperature range of -40°C to +85°C and is available in bulk packaging.

Ptc Resettable Fuses Feature Summary

• Utilizes polymer positive temperature coefficient technology for rapid response to overcurrent events
• Features radial kinked leads optimized for secure through-hole printed circuit board mounting

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Circuit safeguarding in automotive electronics systems
• Protection for telecommunications equipment interfaces
• Power supply input filtering in industrial control modules

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'BK' indicates bulk packaging configuration rather than tape-and-reel delivery. Confirm that the 0.9A hold current aligns with the thermal derating requirements of the target application environment. Ensure compatibility with standard lead-free soldering processes required by RoHS compliance standards before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a 16VDC system requires precise 0.9A continuous current handling with a 1.8A trip threshold. The 120 mOhms initial resistance minimizes power loss in normal operation. Consider the 40A maximum fault current capability for short-circuit scenarios. The radial kinked lead style facilitates automated or manual insertion into PCB layouts requiring 5mm lead spacing.

Ptc Resettable Fuses Part Context

This part belongs to the Eaton PolyTron PTR016V series, which offers a range of resettable fuses rated for 16VDC applications. The series provides various hold currents from 0.1A to 16A, allowing designers to select precise protection levels. The PTR016V0090-BK specifically addresses mid-range current protection needs in compact form factors, serving as a reusable alternative to traditional one-time fusible links.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 16VDC, 0.9A PPTC fuses with similar radial kinked lead configurations. Verify that alternative parts match the 1.8A trip current and 120 mOhms resistance specifications. Ensure the replacement component supports the same -40°C to +85°C operating temperature range and 40A maximum fault current rating for equivalent performance.
