MEM2012D201R

Overview

The MEM2012D201R is a surface-mount LC low-pass EMI filter manufactured by TDK Corporation. It utilizes an LC (PI) circuit topology to provide effective noise suppression in high-speed data lines. The component operates within a temperature range of -40°C to +85°C and features a rated voltage of 6.3V with a maximum current handling capacity of 200mA. Designed for compact applications, it offers a cutoff frequency of 200MHz. The device is housed in a standard 0805 (2012 metric) package, measuring 2.0mm in length, 1.25mm in width, and 0.70mm in height, ensuring compatibility with automated pick-and-place assembly processes.

Procurement Notes

Verify the specific ordering suffix and packaging configuration against official TDK documentation prior to procurement. Confirm that the selected variant matches the required electrical ratings and physical dimensions for your PCB layout. Ensure compliance with relevant environmental standards such as RoHS directives applicable to your region. Cross-reference the manufacturer's part number with distributor catalogs to avoid counterfeit components or incorrect revisions.

Selection Notes

Select this component when a low-pass filter with a 200MHz cutoff frequency is required for data line protection. Consider the 0805 footprint constraints and the 6.3V voltage rating relative to your system's operating conditions. Evaluate the thermal performance within the specified -40°C to +85°C range. Compare alternative packages if board space allows for different form factors while maintaining similar filtering characteristics.
