SMD1210P035TFA

Ptc Resettable Fuses Overview

The Littelfuse SMD1210P035TFA is a POLY-FUSE resettable PPTC device in a 1210 surface-mount package. It features a hold current of 350 mA and a trip current of 700 mA, with a maximum voltage rating of 6 VDC. The component exhibits a resistance of 1.3 Ohms and supports a maximum fault current of 40 A. It operates within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection for circuits by raising resistance as it heats to limit current flow.
• Offers solid-state protection for components and ICs from overcurrent events without requiring replacement after tripping.

Ptc Resettable Fuses Applications

• Protection of actuators, screens, and small motors in automotive applications
• Overcurrent protection for telephony and networking equipment
• Power supply circuit safeguarding

Ptc Resettable Fuses Procurement Notes

Verify the specific manufacturer part number against official Littelfuse documentation to ensure accuracy. Confirm that the required electrical parameters, such as hold current and voltage rating, align with the design specifications. Note that availability status may vary by region and distributor. Check for any RoHS compliance details or specific packaging requirements relevant to the procurement channel.

Ptc Resettable Fuses Selection Notes

Select this component based on its 350 mA hold current and 6 VDC maximum voltage rating to match the circuit's operational limits. Ensure the 1210 surface-mount footprint fits the PCB layout constraints. Consider the 1.3 Ohms resistance value for potential voltage drop implications. Verify that the operating temperature range of -40°C to +85°C meets the environmental conditions of the application.

Ptc Resettable Fuses Part Context

This device belongs to the POLY-FUSE series of resettable fuses manufactured by Littelfuse. These PolySwitch devices are designed for surface-mount installation and provide reusable overcurrent protection. The SMD1210P035TFA specifically utilizes polymeric positive temperature coefficient technology to protect sensitive electronic components from damage due to excessive current.

Ptc Resettable Fuses Replacement Considerations

The 1210L035YR is a confirmed substitute part number with identical electrical characteristics, including 350 mA hold current and 6 VDC rating. Verify package compatibility and lead-free status before substitution.
