FSMD010-R

Ptc Resettable Fuses Overview

The FSMD010-R is a surface-mountable PTC resettable fuse from the FSMD series, manufactured by RFE/Fuzetec. It features an 1812 (4532 Metric) package with a concave profile. The component operates within a voltage range of up to 60V and provides overcurrent protection with a hold current (Ih) of 100 mA. Designed for robust performance, it offers faster time-to-trip characteristics compared to standard variants in the FSMD010 family. The device is rated for operation across a temperature range of -40°C to +85°C, ensuring reliability in various electronic applications requiring compact circuit protection.

Ptc Resettable Fuses Feature Summary

• Solid-state construction enabling surface mount technology integration
• Concave profile design suitable for specific PCB mounting requirements
• Faster trip response time relative to baseline FSMD010 models

Ptc Resettable Fuses Applications

• Portable electronics requiring compact overcurrent protection
• Consumer devices utilizing surface mount assembly processes
• Circuit boards operating within 60V DC limits

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'R' indicates the required concave profile and 1812 footprint when sourcing. Confirm that the 100 mA hold current aligns with the target circuit's normal operating parameters. Ensure the 60V maximum voltage rating exceeds the system's peak voltage. Check compatibility with automated pick-and-place equipment due to the concave shape. Validate thermal management requirements against the specified -40°C to +85°C operating range.

Ptc Resettable Fuses Selection Notes

Select this component when a smaller footprint than 1206 is needed but higher current capacity than 0603 is required. The concave design may be necessary for specific mechanical clearances or soldering profiles. Consider the faster trip time if rapid fault isolation is critical for sensitive downstream components. Compare against standard flat-profile fuses if mechanical height restrictions are less stringent.

Ptc Resettable Fuses Part Context

This part belongs to the FSMD series of surface-mountable PTC resettable fuses. It shares the fundamental positive temperature coefficient technology with other FSMD models but distinguishes itself through its specific 1812 package dimensions and concave physical form. The series is designed to replace traditional fusible links in modern electronics manufacturing.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other FSMD010 variants such as FSMD010-1206-R or FSMD010-0603-R, provided the package size and electrical ratings match the design constraints. Verify that any replacement maintains the 60V rating and 100 mA hold current. Ensure the alternative component supports the same operating temperature range.
