MEM2012TC101

Overview

The MEM2012TC101 is a surface-mount LC (T-Type) EMI filter manufactured by TDK Corporation. It functions as a third-order low-pass filter with one channel, designed for signal line protection. The component features a capacitance value of 100pF and supports a maximum current of 1A. It utilizes an 0805 (2012 Metric) package with three PCB pads for mounting. This device is engineered to suppress electromagnetic interference in high-speed digital circuits.

Feature Summary

• Provides third-order low-pass filtering characteristics for effective noise attenuation
• Utilizes a compact SMD T-type LC network architecture
• Designed for single-channel signal line protection applications

Applications

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

Procurement Notes

Verify the specific datasheet revision and packaging details directly with authorized distributors or TDK documentation before procurement. Confirm that the 0805 footprint and pin configuration match your PCB layout requirements. Ensure compliance with relevant safety standards if used in regulated equipment.

Selection Notes

Select this component when a third-order low-pass response is required for EMI suppression on single-ended signals. The 100pF capacitance and 1A rating suit general-purpose high-speed interfaces. Consider the 0805 package size for space-constrained designs requiring robust filtering performance without excessive board area consumption.

Part Context

This part belongs to TDK's MEM series of passive EMI/RFI filters. These components are widely used in consumer electronics and computer peripherals to meet regulatory emissions standards. The MEM series offers various configurations including RC and LC networks in standard surface-mount packages.

Replacement Considerations

Consult official TDK substitution guides for verified alternatives. Generic equivalents may not replicate the precise T-type LC impedance characteristics or third-order roll-off behavior required for specific high-speed signal integrity applications.
