PTSLR12066V175

Ptc Resettable Fuses Overview

The PTSLR12066V175 is a surface-mount polymer PTC resettable fuse manufactured by Eaton Electronics Division. It belongs to the PTSLR series, designed for low resistance applications in compact footprints. The device features a maximum voltage rating of 6 VDC and a hold current (Ih) of 1.75 A. Its trip current (It) is specified at 3.5 A, with a maximum fault current rating of 50 A. The initial resistance (Ri) is typically 40 mOhms. Operating within a temperature range of -40°C to +85°C, it utilizes an SMD/SMT termination style suitable for PCB mounting.

Ptc Resettable Fuses Feature Summary

• Polymer PTC technology provides automatic reset functionality after fault conditions clear.
• Low resistance design minimizes power loss and heat generation in sensitive circuits.
• Compact 1210 surface-mount package facilitates high-density board layouts.

Ptc Resettable Fuses Applications

• Portable electronic devices requiring overcurrent protection
• Battery packs and battery management systems
• Data port protection for USB and communication interfaces

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with current RoHS and REACH standards. Confirm that the ordering quantity matches the required packaging format, such as cut tape or reel, as availability may vary by region. Cross-reference the component marking code on received units with official documentation to prevent counterfeit substitution.

Ptc Resettable Fuses Selection Notes

Select this component when circuit requirements demand a low holding current near 1.75 A and a strict 6 VDC voltage limit. The low resistance characteristic makes it suitable for applications where minimizing voltage drop and thermal impact is critical. Ensure the expected operating ambient temperature remains within the -40°C to +85°C range to maintain reliable tripping performance.

Ptc Resettable Fuses Part Context

This part is part of the PTSLR series from Eaton, which focuses on low-resistance polymeric resettable fuses. The series offers various current ratings in standard SMD packages like 1210, providing alternatives to traditional fusible resistors. It serves as a reusable protection element in modern electronics, replacing single-use fuses to reduce maintenance and improve system reliability.

Ptc Resettable Fuses Replacement Considerations

Compatible substitutes include other 1210 footprint PTCs with similar 1.75 A hold current and 6 VDC ratings, such as the Bourns MF-MSMF0175-2 or Littelfuse FCMF175-2. Verify that alternative components match the trip current and maximum fault current specifications to ensure equivalent circuit protection levels.
