MEM2012S35R0T

Overview

The MEM2012S35R0T is a third-order LC T-type EMI filter manufactured by TDK Corporation. It operates as a low-pass filter with a cutoff frequency of 35MHz and supports a maximum current of 100mA. The component utilizes an SMD package corresponding to the 0805 (2012 Metric) dimension, featuring a three-pad configuration for surface mounting. It complies with RoHS standards and is designed for effective noise suppression in high-frequency circuits.

Feature Summary

• Third-order LC T-type architecture for enhanced attenuation
• Low-pass filtering capability up to 35MHz cutoff
• Compact 0805 surface-mount footprint

Applications

• High-speed data line noise suppression
• Power supply input filtering
• EMI reduction in portable electronics

Procurement Notes

Verify that the specific part number matches the required 35MHz cutoff and 100mA rating. Confirm the 0805 package dimensions align with the PCB layout. Ensure compliance with RoHS directives if applicable to the final assembly. Cross-reference the manufacturer's latest datasheet for any updates on recommended soldering profiles or storage conditions prior to integration.

Selection Notes

Select this component when a third-order attenuation profile is necessary within a constrained 0805 space. The 35MHz cutoff suits applications requiring suppression of higher frequency noise while passing lower frequencies. Consider the 100mA current limit against the circuit's operational requirements. Evaluate the trade-off between the compact size and the need for robust EMI performance compared to first-order alternatives.

Part Context

This component belongs to TDK's MEM series of passive filters. It is engineered for surface-mount technology, offering a solution for integrating complex filtering functions into space-sensitive designs. The LC T-type structure provides superior stopband rejection compared to simpler RC networks, making it suitable for demanding electromagnetic compatibility scenarios.
