ACM2012-121-2P-TL002

Overview

The ACM2012-121-2P-TL002 is a surface-mount common mode filter from the TDK ACM series, designed for high-speed differential signal lines. It features a compact 2012 metric (0805) package with dimensions of 2.0mm x 1.2mm x 1.3mm. The component provides an impedance of 120 Ohms at 100 MHz and supports a maximum DC current of 370 mA. Its maximum DC resistance is 220 mOhms, and it operates within a temperature range of -40°C to +85°C.

Feature Summary

Achieves significant noise suppression while maintaining required common mode filter characteristics through a wound-type chip design.
Provides high common mode impedance at 100 MHz to effectively suppress noise on differential signal lines.
Maintains low differential mode impedance to minimize impact on high-speed signal integrity.

Applications

USB cables for computers and peripheral devices
IEEE1394 and ETHERNET cables for computers and STBs
LVDS and Panel Link cables for liquid crystal screens

Procurement Notes

Verify the specific suffix against official documentation, as variations such as T002 or TL002 may indicate differences in packaging or manufacturing origin rather than electrical function. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the part number with the latest product change notices to ensure availability and specification consistency.

Selection Notes

Select this component when space constraints require a 0805 footprint for high-speed data line filtering. Ensure the 370 mA current rating meets the operational requirements of the target circuit. Verify that the 120 Ohm impedance at 100 MHz aligns with the frequency spectrum of the noise to be suppressed without attenuating the desired differential signal.

Part Context

This component belongs to the TDK ACM series of common mode chokes specifically engineered for signal lines. The series offers various impedance values and current ratings in compact packages to address EMI/RFI issues in portable electronics and computer peripherals. The ACM2012 variant represents the smallest form factor in the series, prioritizing miniaturization for dense PCB layouts.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult TDK technical support for direct equivalents within the ACM series or other manufacturers' offerings that match the 2012 package, 120 Ohm impedance, and 370 mA current specifications.
