MEM2012SC101T001

Overview

The TDK MEM2012SC101T001 is a surface-mount EMI filter circuit designed for signal line protection. It features an LC (T-Type) third-order low-pass configuration within a compact 0805 (2012 Metric) package measuring 2mm x 1.25mm x 0.8mm. The component provides 10dB attenuation across the 300MHz to 2000MHz frequency range and supports a maximum current of 1A. It operates reliably within a temperature range of -40°C to +85°C.

Feature Summary

• Third-order low-pass filtering architecture for enhanced noise suppression
• Compact 0805 surface-mount footprint for space-constrained designs
• High current handling capability suitable for active signal lines

Applications

• Signal line EMI/RFI suppression in portable electronics
• Noise filtering for high-speed data interfaces
• EMI mitigation in automotive infotainment systems

Procurement Notes

Verify the specific suffix 'T001' corresponds to the required tape-and-reel packaging format during procurement. Confirm that the 1A current rating aligns with the peak operational demands of the target circuit. Ensure compatibility with standard reflow soldering profiles for 0805 components to maintain device integrity.

Selection Notes

Select this component when a third-order response is required for superior attenuation compared to first-order alternatives. The 10dB performance at 300-2000MHz makes it suitable for broadband noise reduction. Consider the 0805 package size if board real estate is limited but higher filtering order is necessary than what smaller packages allow.

Part Context

This part belongs to TDK's MEM series of miniature EMI filters. These components integrate passive LC networks into small surface-mount packages, replacing discrete components to save board space and improve consistency. The SC variant typically denotes specific terminal configurations or internal topology optimized for signal integrity.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical characteristics carefully if considering alternative manufacturers' third-order low-pass filters in the 0805 package.
