MEM2012V211RT

Overview

The MEM2012V211RT is a surface-mount LC (Pi) EMI filter manufactured by TDK Corporation. It functions as a fifth-order low-pass filter with one channel, designed for signal line noise suppression in compact electronic devices. The component operates within a 0805 (2012 Metric) package and supports a maximum current of 100 mA. It features a rated voltage of 10 V and provides effective attenuation at frequencies up to 210 MHz. The device is RoHS compliant and utilizes a three-pad configuration for PCB mounting.

Feature Summary

• Provides fifth-order low-pass filtering characteristics for enhanced high-frequency noise suppression
• Utilizes an LC Pi-network topology for efficient EMI/RFI mitigation
• Designed for space-constrained applications with a compact 0805 surface-mount footprint

Applications

• Noise suppression on data lines in portable consumer electronics
• EMI filtering for USB and high-speed digital interfaces
• Signal integrity enhancement in mobile communication modules

Procurement Notes

Verify the complete manufacturer part number against official TDK documentation to ensure correct specification matching. Confirm that the suffix indicates the standard reel packaging format required for automated assembly processes. Cross-reference the RoHS compliance status with current regulatory requirements for your target market before finalizing procurement orders.

Selection Notes

Select this component when fifth-order attenuation is required within a minimal board area constraint. Ensure the operating voltage does not exceed the 10 V rating and that the signal current remains below 100 mA. Verify that the 0805 footprint aligns with existing PCB layout designs and that the frequency response meets the specific noise spectrum requirements of the application.

Part Context

This component belongs to TDK's MEM series of miniature EMI filters. These components are engineered for modern electronics requiring significant noise reduction without increasing board size. The MEM series typically integrates passive LC elements into standardized surface-mount packages, offering a balance between performance density and manufacturing ease for high-volume production environments.

Replacement Considerations

Consult official TDK substitution guides for verified equivalents. Generic cross-references may not match the fifth-order characteristic or specific impedance profiles. Validate any alternative part against the original datasheet parameters to ensure compatibility with the circuit design.
