FSMD110-33R

Ptc Resettable Fuses Overview

The FSMD110-33R is a surface-mountable PTC resettable fuse from the FSMD1812 series. It features a maximum voltage rating of 33V and a hold current (Ih) of 1.1A. The component utilizes an 1812 (4532 Metric) concave package design, suitable for automated assembly processes. It operates within a temperature range of -40°C to +85°C. The device provides overcurrent protection by increasing resistance in response to excessive current flow, resetting automatically once conditions normalize.

Ptc Resettable Fuses Feature Summary

• Surface mount construction with concave profile for stable placement
• Automatic reset functionality upon cooling after fault clearance
• Compliance with cUL and TUV safety agency approvals

Ptc Resettable Fuses Applications

• Circuit board protection for portable electronic devices
• Overcurrent safeguarding in interconnected consumer electronics
• Protection of low-voltage signal lines in compact modules

Ptc Resettable Fuses Procurement Notes

Verify that the ordering suffix 'R' corresponds to tape and reel packaging as indicated by distributor listings. Confirm the specific hold current and voltage ratings match the target circuit requirements before integration. Ensure the supplier provides valid RoHS compliance documentation and original manufacturer datasheets to guarantee component authenticity and performance consistency.

Ptc Resettable Fuses Selection Notes

Select this component for applications requiring low-profile surface mounting where space constraints are critical. The 33V rating limits suitability to low-voltage circuits only. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +85°C range. Consider the concave package geometry for reflow soldering compatibility and mechanical stability during assembly.

Ptc Resettable Fuses Part Context

This part belongs to the FSMD1812 series of surface mountable PTC resettable fuses manufactured by Fuzetec Technology Co., Ltd. The series is designed for compact electronic applications requiring reliable overcurrent protection. The FSMD110-33R variant specifically addresses needs for 1.1A hold current in small form factor designs.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 1812 package, 33V max voltage, and 1.1A hold current specifications. Verify that alternative components offer comparable trip characteristics and thermal performance. Cross-reference safety approvals such as cUL and TUV if regulatory compliance is mandatory for the end application.
