MEM2012S201RT

Overview

The MEM2012S201RT is a third-order low-pass EMI filter from the TDK MEM series, designed for signal line noise suppression. It features an LC T-type circuit topology with a single channel and a rated current of 250 mA. The component utilizes a surface-mount package with dimensions corresponding to the EIA 0603 metric (1.6mm x 0.8mm). It is engineered to attenuate electromagnetic interference in high-speed digital interfaces.

Feature Summary

• LC T-type circuit configuration for effective noise filtering
• Third-order low-pass characteristic for enhanced attenuation
• Single-channel design for dedicated signal line protection

Applications

• High-speed data interface noise suppression
• USB port EMI filtering
• HDMI signal line protection

Procurement Notes

Verify the specific datasheet revision and electrical characteristics directly from TDK official documentation before integration. Confirm that the 250 mA rating aligns with the target application's peak current requirements. Ensure the EIA 0603 footprint matches the PCB layout constraints. Cross-reference the suffix RT with manufacturer specifications to confirm reel packaging details and tape-and-reel dimensions.

Selection Notes

Select this component when a third-order low-pass response is required for single-ended signal lines. The 250 mA current rating suits moderate-speed digital interfaces. Consider the physical size compatibility with the assembly process. Evaluate insertion loss requirements against the filter's attenuation profile in the target frequency range. Ensure the operating temperature range meets system environmental standards.

Part Context

This part belongs to the TDK MEM series of passive EMI filters. The series offers various capacitance and inductance values within standardized footprints. These components are designed to replace discrete LC networks, saving board space and improving consistency in high-frequency noise suppression applications across consumer and industrial electronics.

Replacement Considerations

Consult TDK official substitution guides for verified alternatives. Ensure any substitute maintains the same circuit topology, current rating, and physical footprint. Verify that the replacement part meets the same regulatory certifications and performance specifications.
