SMDH1206B050TF

Ptc Resettable Fuses Overview

The YAGEO SMDH1206B050TF is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for high-temperature applications. It operates within the SMDH series and meets AEC-Q200 automotive qualification standards. The component features a 1206 package with dimensions of 3 mm length, 1.5 mm width, and 0.35 mm height. Key electrical parameters include a hold current of 500 mA, a trip current of 1.0 A, and a maximum voltage rating of 16 VDC. It has a resistance of 150 mOhms and a power dissipation of 0.6 W. The device functions reliably across an operating temperature range from -40°C to +125°C.

Ptc Resettable Fuses Feature Summary

• Provides overcurrent protection through automatic circuit interruption upon thermal activation.
• Supports re-closing functionality after fault conditions are removed and the device cools down.
• Complies with AEC-Q200 automotive qualification requirements for reliability in harsh environments.

Ptc Resettable Fuses Applications

• Automotive electronic circuits requiring high-temperature tolerance
• Protection of low-voltage DC power lines
• Overcurrent safeguarding in compact surface-mount assemblies

Ptc Resettable Fuses Procurement Notes

Verify that the specific part number matches the required hold current and voltage ratings for the target application. Confirm compliance with AEC-Q200 standards if automotive usage is intended. Ensure the selected package size fits the PCB layout constraints. Check datasheet specifications for trip current and resistance values to validate circuit performance under fault conditions.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable fuse with a 500 mA hold current and 16 VDC rating is needed. Consider the 1206 footprint for space-constrained designs. Evaluate the high-temperature capability up to 125°C for demanding environments. Compare trip current characteristics against expected surge currents to ensure proper protection without nuisance tripping.
