SMD1210P010TFA

Ptc Resettable Fuses Overview

The Littelfuse SMD1210P010TFA is a surface-mount PolySwitch resettable PPTC fuse designed for overcurrent protection. It features a 1210 (3225 metric) package with a hold current of 100 mA and a trip current of 200 mA. The device supports a maximum voltage rating of 6 V and can withstand fault currents up to 40 A. Initial resistance is typically 1.3 Ohms, rising to a maximum of 15 Ohms after tripping. It operates within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection by raising resistance as it heats to limit current flow
• Automatically resets to a low-resistance state once the fault condition is removed and the device cools
• Designed for surface mount installation directly onto printed circuit boards

Ptc Resettable Fuses Applications

• Protection of portable electronics circuits from overcurrent events
• Overcurrent safeguarding for battery-powered devices
• Circuit protection in telecommunications equipment signal lines

Ptc Resettable Fuses Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified partners. Confirm that the specific part number matches project requirements for electrical ratings and package dimensions. Request official datasheets and certification documents to ensure compliance with RoHS standards and other regulatory requirements before finalizing procurement decisions.

Ptc Resettable Fuses Selection Notes

Select this component based on the required hold current of 100 mA and the 6 V maximum operating voltage. Ensure the application environment stays within the specified -40°C to +85°C temperature range. Consider the 1210 footprint constraints and the need for automatic reset functionality compared to one-time fuses. Verify compatibility with standard reflow soldering processes used in the manufacturing line.
