SMDH1206B025TF

Ptc Resettable Fuses Overview

The YAGEO SMDH1206B025TF is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for high-temperature automotive applications. It operates within the SMDH series and features a 1206 package dimension of 3 mm length, 1.5 mm width, and 0.35 mm height. The device maintains a holding current of 250 mA and trips at 810 mA, with a maximum voltage rating of 16 V. It dissipates 600 mW of power and exhibits a resistance of 350 mOhms. Rated for a fault current of 20 A, it functions reliably between -40°C and +125°C.

Ptc Resettable Fuses Feature Summary

• Provides overcurrent protection through automatic trip and reset functionality using PPTC technology.
• Complies with AEC-Q200 qualification standards specifically for automotive electronic components.
• Engineered to maintain stable performance under elevated operating temperatures up to 125°C.

Ptc Resettable Fuses Applications

• Automotive circuit protection systems requiring AEC-Q200 compliance
• High-temperature electronic module safeguarding
• Low-voltage DC bus overcurrent protection

Ptc Resettable Fuses Procurement Notes

Verify that the specific part number matches the required electrical ratings, particularly the 16 V maximum voltage and 250 mA holding current. Confirm the component meets AEC-Q200 automotive qualification requirements if intended for vehicle electronics. Ensure the 1206 surface mount package dimensions align with the target PCB layout constraints. Check datasheet specifications for thermal dissipation limits and trip characteristics to validate suitability for the specific application environment.

Ptc Resettable Fuses Selection Notes

Select this component when low voltage operation near 16 V is required alongside high-temperature resilience. The 250 mA holding current suits circuits needing moderate continuous current protection. Consider the 350 mOhms resistance for minimal voltage drop impact. The AEC-Q200 certification makes it appropriate for automotive environments where standard industrial fuses may not suffice due to thermal stress.

Ptc Resettable Fuses Part Context

This device belongs to the YAGEO SMDH series of resettable fuses, specialized for robust surface-mount integration. It utilizes polymeric technology to offer reusable overcurrent protection without manual replacement. The 1206 form factor allows for compact PCB designs while providing adequate thermal mass for high-temperature stability in demanding operational conditions.
