SMD0805B010TF

Ptc Resettable Fuses Overview

The YAGEO SMD0805B010TF is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for circuit protection. It operates within a maximum voltage of 15 VDC and features a hold current of 100 mA with a trip current of 300 mA. The component exhibits an initial resistance of 6 Ohms and can withstand a maximum fault current of 100 A. It is housed in a compact 0805 (2012 metric) package, measuring 2.2 mm in length, 1.5 mm in width, and 1 mm in height. The device supports a power dissipation of 500 mW and functions reliably across a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix to confirm the required tape and reel configuration, as packaging variations may exist. Ensure that the selected variant meets the necessary RoHS compliance standards for your manufacturing process. Confirm that the ambient operating temperatures remain within the specified -40°C to +85°C range during deployment. Cross-reference the datasheet to validate that the 15 VDC rating aligns with your system's maximum voltage requirements.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile, surface-mount solution is required for circuits operating at 15 VDC or lower. The 100 mA hold current makes it suitable for protecting low-power signal lines and data ports. Consider the 6 Ohm initial resistance to ensure it does not adversely affect signal integrity in sensitive applications. Evaluate the thermal environment to ensure the device can dissipate heat effectively without premature tripping under normal load conditions.

Ptc Resettable Fuses Part Context

This part belongs to the YAGEO SMD series of PPTC resettable fuses, which are engineered for high-reliability protection in modern electronics. The series offers various current ratings and voltage capabilities to suit different application needs. These components serve as reusable alternatives to traditional one-time fuses, reducing maintenance costs and improving system uptime by automatically resetting after the fault condition clears.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other YAGEO PPTC fuses with identical electrical parameters and package dimensions, such as variants with different current ratings if the design allows. Cross-manufacturer replacements must match the 0805 footprint, 15 VDC rating, and 100 mA hold current to ensure mechanical and electrical compatibility.
