SMD1210B150TF/12

Ptc Resettable Fuses Overview

The YAGEO SMD1210B150TF/12 is a polymeric PTC resettable fuse designed for surface mount applications. It features a maximum voltage rating of 12V and a holding current (Ih) of 1.5A. The component utilizes a 1210 (3225 Metric) concave package with dimensions of 0.127 inches in length and 0.102 inches in width. Initial resistance (Ri) is specified at a minimum of 15 mohms, while post-trip resistance (R1) has a maximum limit of 75 mohms. The device operates within a temperature range of -40°C to +85°C and exhibits a trip time of approximately 1 second under fault conditions.

Ptc Resettable Fuses Feature Summary

• Provides miniature surface mount overcurrent protection through positive temperature coefficient polymer technology.
• Automatically resets to low-resistance state after fault condition removal, eliminating the need for manual replacement.
• Features a concave 1210 package design suitable for automated surface mount assembly processes.

Ptc Resettable Fuses Applications

• Portable electronic devices requiring compact circuit protection
• Consumer electronics power input lines
• Automotive grade applications certified to AEC-Q200 standards

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix /12 corresponds to the required 12V voltage rating, as other variants exist within the series. Confirm that the 1.5A holding current aligns with the target circuit's normal operating parameters. Ensure the 1210 footprint matches the PCB layout constraints. Check RoHS compliance status if restricted substances are a concern for the final product assembly.

Ptc Resettable Fuses Selection Notes

Select this component when a 12V system requires resettable protection with a 1.5A continuous current capacity. The 1210 form factor offers a balance between current handling and board space efficiency compared to smaller packages. Consider the tripping characteristics and residual resistance limits to ensure compatibility with sensitive downstream components during fault events.

Ptc Resettable Fuses Part Context

This part belongs to the YAGEO SMD1210 series of polymeric PTC resettable fuses. The series provides miniature surface mount solutions with holding currents ranging from 0.05A to 2.0A. The /12 designation specifically identifies the 12V voltage variant within this family, distinguishing it from other ratings like 6V or 16V models.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 12V, 1.5A PTC fuses in the 1210 package such as the SMD1210B150TF/16 if voltage tolerance allows, or generic equivalents from manufacturers offering AEC-Q200 certified automotive-grade polymer fuses in identical footprints.
