FSMD020-R

Ptc Resettable Fuses Overview

The FSMD020-R is a surface-mountable PTC resettable fuse from the FSMD1812 series. It features a maximum voltage rating of 30V and a hold current (Ih) of 200 mA. The trip current (It) is specified at 400 mA, with a maximum fault current capacity of 100 A. The component operates within a temperature range of -40°C to +85°C. It utilizes an 1812 (4532 Metric) concave package for surface mount applications.

Ptc Resettable Fuses Feature Summary

• Provides overcurrent protection through self-resetting polymer positive temperature coefficient technology
• Designed for surface mounting on printed circuit boards
• Capable of handling high fault currents up to 100 A

Ptc Resettable Fuses Applications

• Portable electronic devices
• Consumer electronics circuits
• Communication equipment protection

Ptc Resettable Fuses Procurement Notes

Verify the specific datasheet version for the FSMD020-R to confirm exact electrical tolerances and thermal characteristics. Ensure the supplier provides official documentation from Fuzetec or authorized distributors to guarantee component authenticity and performance consistency in critical circuit designs.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile surface mount solution is required for 30V circuits. The 200 mA hold current suits applications needing precise overcurrent limiting without nuisance tripping during normal operation. Consider the 1812 package size for board space constraints.

Ptc Resettable Fuses Part Context

This part belongs to the FSMD series of surface mountable PTC resettable fuses manufactured by Fuzetec Technology Co., Ltd. The series includes various hold current ratings and package sizes, such as the FSMD1206 variant, offering flexible options for different circuit protection requirements across consumer and industrial electronics.

Ptc Resettable Fuses Replacement Considerations

The FSMD020-1206-R is a related variant in the same product family but utilizes a 1206 package instead of 1812. Verify footprint compatibility before substitution. No other direct cross-model substitutes are confirmed in public documentation.
