MEM2012S201R0T

Overview

The MEM2012S201R0T is a third-order LC (T-Type) EMI/RFI low-pass filter manufactured by TDK Corporation. Designed for surface-mount applications in the 0805 (2012 Metric) package, this component features three pads and supports a maximum current of 250mA. It provides effective noise suppression with a cutoff frequency of 200MHz. The device is classified as Not For New Designs, indicating it is a legacy part within the manufacturer's portfolio.

Feature Summary

• Third-order LC T-Type topology for enhanced attenuation
• Compact 0805 surface-mount footprint
• Low-pass filtering characteristic for EMI/RFI suppression

Applications

• Power supply circuits
• Battery chargers
• Portable electronic devices

Procurement Notes

Verify availability status carefully as the component is designated Not For New Designs. Confirm package dimensions and pin configuration against current project requirements before integration. Ensure compatibility with existing PCB layouts due to potential obsolescence constraints.

Selection Notes

Select this component when space-constrained designs require third-order filtering performance in an SMD format. Evaluate thermal management capabilities relative to the 250mA rating. Consider lifecycle status implications for long-term production runs.

Part Context

This EMI filter belongs to TDK's MEM series of passive components designed for high-frequency noise reduction. It utilizes ceramic technology to achieve stable electrical characteristics across operating conditions. The product line targets consumer electronics and industrial control systems requiring compact signal integrity solutions.

Replacement Considerations

Check for updated TDK series replacements or equivalent third-party filters with matching 200MHz cutoff and 0805 footprint. Verify parameter alignment including current handling and insertion loss specifications.
