SMD1210B005TF

Ptc Resettable Fuses Overview

The YAGEO SMD1210B005TF is a polymeric self-resetting fuse (PPTC) from the SMD1210 series, designed for surface mount applications. It features a holding current of 50 mA and a trip current of 150 mA. The device supports a maximum voltage of 30 VDC and can handle a maximum fault current of 100 A. Its initial resistance is typically low, with a maximum value of 1.5 Ohms after tripping. The component operates within a temperature range of -40°C to +85°C and is housed in a standard 1210 (3225 metric) package.

Ptc Resettable Fuses Feature Summary

• Provides miniature surface mount overcurrent protection using polymeric PPTC technology.
• Automatically resets to a low-resistance state once the fault condition is removed and the device cools down.
• Designed for high reliability in protecting sensitive electronic circuits against overcurrent events.

Ptc Resettable Fuses Applications

• Portable electronics circuit protection
• Battery pack overcurrent safeguarding
• Data line surge protection
• Consumer appliance input stages

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix and voltage rating during procurement, as variations such as SMD1210B005TF/60 exist with different maximum voltage specifications (e.g., 60V). Ensure the required holding and trip currents match the target circuit design. Confirm packaging preferences, as components are available in cut tape or reel formats depending on the distributor source.

Ptc Resettable Fuses Selection Notes

Select this component when a compact 1210 footprint is required for low-current protection applications. The 50 mA holding current suits small signal lines, while the 30 VDC rating limits its use to low-voltage systems. Consider thermal derating factors if operating near the upper temperature limit. Compare against higher current variants in the same series if the application demands greater load capacity.

Ptc Resettable Fuses Part Context

This part belongs to the YAGEO SMD1210 series of resettable fuses, which offers a range of holding currents from 0.05A to 2.0A. The series is characterized by its small size and ability to replace traditional fusible links in surface mount designs. It serves as a reusable alternative to one-time fuses, enhancing system maintainability.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 1210-sized PPTC fuses with identical 50 mA holding current and 30 VDC ratings. Verify that replacement parts match the maximum trip current and residual resistance specifications to ensure equivalent circuit performance and protection levels.
