MEM2012F75R0T001

Overview

The MEM2012F75R0T001 is a three-terminal EMI filter from TDK Corporation, designed for signal line applications. It features an LC (Pi) topology with one channel and a cutoff frequency of 75MHz. The device provides 20dB attenuation between 700MHz and 2GHz. Rated for 200mA current, it operates within a temperature range of -40°C to +85°C. The component utilizes a compact 0805 (2012 Metric) surface-mount package measuring 2mm x 1.25mm x 0.85mm.

Feature Summary

• Provides steep attenuation characteristics for stringent electromagnetic interference suppression
• Utilizes multi-layer chip construction for high-density circuit board mounting
• Functions as a third-order low-pass filter for signal lines

Applications

• Signal line filtering in electronic equipment
• Electromagnetic interference suppression in high-density circuits
• Noise reduction in devices requiring steep attenuation characteristics

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters and mechanical dimensions. Ensure compatibility with surface-mount assembly processes given the 0805 package size. Cross-reference official specifications for operating temperature limits and current ratings before integration into final designs.

Selection Notes

Select this component when signal line filtering requires a compact footprint and high attenuation performance. The 75MHz cutoff frequency suits applications needing effective noise suppression above 700MHz. Consider the 200mA rating and -40°C to +85°C operating range against system requirements.
