FSMD005-1210-R

Ptc Resettable Fuses Overview

The FSMD005-1210-R is a surface mountable polymeric positive temperature coefficient (PPTC) resettable fuse from the FSMD1210 series. It features a 60V maximum voltage rating and a hold current of 50 mA. The component utilizes a 1210 (3225 Metric) package with concave terminals for reliable SMT attachment. Its resistance ranges from 3.6 Ohms minimum to 5 Ohms maximum, providing effective overcurrent protection in compact electronic designs.

Ptc Resettable Fuses Feature Summary

• Polymeric PTC technology enables automatic circuit recovery after fault clearance
• Concave terminal design ensures stable surface mounting on PCBs
• Compact 1210 footprint supports high-density circuit board layouts

Ptc Resettable Fuses Applications

• Automotive electronics circuits
• Lithium battery protection systems
• Portable consumer devices

Ptc Resettable Fuses Procurement Notes

Verify datasheet specifications against application requirements before procurement. Confirm that the 60V rating and 50mA hold current align with system parameters. Ensure the 1210 package dimensions match the PCB layout constraints. Check for RoHS compliance status if required by project standards.

Ptc Resettable Fuses Selection Notes

Select this component when space-constrained designs require resettable overcurrent protection. The 1210 package offers a balance between current handling and size. Consider the 60V limit for low-voltage applications. Evaluate thermal management needs as PPTC devices generate heat during trip conditions.

Ptc Resettable Fuses Part Context

This part belongs to the FSMD1210 series of surface mountable PTC resettable fuses manufactured by Fuzetec Technology. The series provides various current ratings within the same 1210 package form factor, allowing designers to standardize footprints while adjusting protection levels for different circuit branches.

Ptc Resettable Fuses Replacement Considerations

Compatible substitutes include other FSMD1210 series parts with matching electrical characteristics. Verify that alternative components maintain the same 60V rating and similar hold current values to ensure circuit compatibility without redesigning the PCB layout.
