SMDL1206B400TF

Ptc Resettable Fuses Overview

The YAGEO SMDL1206B400TF is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for overcurrent protection. It operates within a maximum voltage of 6V and maintains a hold current of 4A, with a trip current of 8A and a maximum fault current rating of 50A. The device features a low resistance of 3 milliohms and dissipates up to 0.8W of power. Housed in a 1206 (3216 metric) concave package measuring 3.20mm by 1.65mm with a maximum thickness of 1.40mm, it functions reliably across an operating temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after fault conditions without manual replacement
• Features low initial resistance to minimize signal loss in protected circuits
• Utilizes a concave surface mount package for optimized board space utilization

Ptc Resettable Fuses Applications

Ptc Resettable Fuses Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the received parts match the specific SMDL1206B400TF designation and packaging specifications. Ensure storage conditions comply with moisture sensitivity levels to maintain reliability before soldering.

Ptc Resettable Fuses Selection Notes

Select this component when circuit design requires a compact, self-resetting protection mechanism for low-voltage applications. The 4A hold current and 6V rating define the operational limits. Evaluate thermal management requirements as the device relies on ambient cooling during tripped states.

Ptc Resettable Fuses Part Context

This part belongs to the SMDL series of low-resistance PPTC devices from YAGEO. The series targets applications demanding minimal voltage drop and rapid response times. The 1206 form factor allows integration into standard surface-mount assembly processes used in modern electronics manufacturing.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 1206 concave footprint, 6V max voltage, and 4A hold current ratings. Verify that alternative PPTC devices offer comparable trip characteristics and thermal performance to ensure circuit integrity.
