MEM2012T201R0T0S1

Overview

The MEM2012T201R0T0S1 is a surface-mount EMI/RFI filter manufactured by TDK Corporation. It utilizes an LC (T-Type) topology configured as a third-order low-pass filter with a single channel. The component operates within a rated voltage of 10V and supports a continuous current of 250 mA. Its physical dimensions are 2.00mm x 1.25mm, corresponding to the 0805 (2012 Metric) package size. The device functions effectively in an operating temperature range from -40°C to +85°C and features a cutoff frequency of 200MHz.

Feature Summary

• LC T-Type architecture providing third-order low-pass filtering characteristics for effective noise suppression
• Compact 0805 surface-mount footprint designed for space-constrained printed circuit board layouts
• Single-channel configuration optimized for signal integrity protection on data lines

Applications

• Data line protection for mobile devices
• EMI suppression in portable electronics
• Signal conditioning in compact consumer hardware

Procurement Notes

Verify the complete part number including suffixes to ensure correct termination and packaging specifications. Confirm RoHS compliance status matches project requirements. Check datasheet for specific impedance values and insertion loss curves relevant to your frequency spectrum. Ensure compatibility with standard reflow soldering profiles for 0805 components.

Selection Notes

Select this component when a third-order low-pass response is required for high-frequency noise attenuation in tight spaces. The 250mA current rating suits low-power data lines rather than power distribution. Verify that the 10V rated voltage exceeds the maximum signal swing in the application. Consider the 200MHz cutoff frequency against the target signal bandwidth to prevent unwanted signal degradation.

Part Context

This component belongs to TDK's MEM series of miniature EMI filters. These parts are engineered for high-density PCB designs where traditional through-hole or larger SMD filters cannot fit. The series typically offers various cutoff frequencies and current ratings within standardized footprints to facilitate design-in flexibility across different electronic product categories.

Replacement Considerations

Consult official TDK documentation for direct cross-references. Ensure any substitute maintains the same LC T-type topology and 0805 footprint. Verify that replacement parts match the 200MHz cutoff frequency and 250mA current handling capabilities to preserve circuit performance.
