ACM2012-102-2P-T001

Overview

The TDK ACM2012-102-2P-T001 is a surface-mount common mode filter designed for high-speed differential and general signal lines. It features a two-channel configuration within an 0805 (2012 metric) package, measuring 2.0 mm in length, 1.2 mm in width, and 1.3 mm in height. The component exhibits an impedance of 1000 Ohms at 100 MHz and supports a maximum DC current of 190 mA with a maximum DC resistance of 1.5 Ohms. It operates reliably within a temperature range of -40°C to +105°C and holds AEC-Q200 qualification.

Feature Summary

• Provides effective noise suppression for high-speed differential signal lines and general signal circuits.
• Constructed in a compact 0805 surface-mount footprint suitable for space-constrained PCB layouts.
• Engineered for automotive reliability through AEC-Q200 qualification standards.

Applications

• High-speed differential signal line filtering
• General signal line noise suppression
• Automotive electronic systems requiring AEC-Q200 compliance

Procurement Notes

Verify the specific suffix T001 against official TDK documentation to confirm packaging details and exact electrical tolerances. Ensure compatibility with standard reflow soldering profiles for SMD components. Cross-reference the impedance value at 100 MHz with circuit requirements to confirm adequate attenuation characteristics for the target application frequency.

Selection Notes

Select this component when designing for high-speed data interfaces requiring robust common mode noise rejection in a minimal footprint. The 190 mA current rating suits low-power signal lines rather than power delivery paths. Consider the 1.5 Ohm DCR impact on signal integrity if driving sensitive loads. The wide operating temperature range supports deployment in demanding environmental conditions.

Part Context

This part belongs to the TDK ACM series of common mode chokes, specifically optimized for signal line protection. The ACM2012 designation indicates the 0805 package size, while the suffix denotes specific impedance and packaging variations. These filters are integral to maintaining signal integrity in modern electronics by attenuating electromagnetic interference without distorting differential signals.

Replacement Considerations

Consult official TDK substitution guides for direct equivalents. Verify that any alternative maintains the 1000 Ohm impedance at 100 MHz and 190 mA current rating. Ensure the replacement package matches the 0805 dimensions and thermal characteristics for seamless integration.
