Overview
The TDK ACM2012-900-2P-T001 is a surface-mount common mode filter designed for high-speed differential and general signal lines. It features an impedance of 90 Ohms at 100 MHz and supports a maximum DC current of 400 mA with a maximum DC resistance of 190 mOhms. The component operates within a temperature range of -40°C to +105°C and holds AEC-Q200 qualification. Its compact 0805 (2012 metric) package measures 2.00 mm in length, 1.20 mm in width, and has a maximum height of 1.30 mm.
Feature Summary
- Provides excellent common mode impedance and noise suppression for signal integrity
- Compact low-profile design suitable for space-constrained applications
- Qualified for automotive environments under AEC-Q200 standards
Applications
- Automobile signal line filtering
- High-speed differential signal line protection
- General signal line noise suppression
Procurement Notes
Verify the specific suffix 'T001' against official TDK documentation to confirm reel packaging details and tape specifications. Ensure the procurement channel provides valid traceability for AEC-Q200 qualified components intended for automotive or industrial use. Cross-reference the impedance value of 90 Ohms at 100 MHz with system requirements before ordering.
Selection Notes
Select this component when designing circuits requiring noise suppression on high-speed differential signals with limited board space. The 400 mA current rating and 190 mOhms DCR are critical parameters for power loss considerations. The AEC-Q200 qualification makes it suitable for automotive applications where reliability under varying thermal conditions is required.
Part Context
This part belongs to the TDK ACM series of common mode filters, which are engineered for suppressing electromagnetic interference in compact electronic designs. The ACM2012 series specifically targets applications demanding small footprints, such as mobile devices and automotive electronics, while maintaining effective noise attenuation characteristics across relevant frequency bands.
Replacement Considerations
Consult official TDK substitution guides for compatible parts within the ACM series that match the 90 Ohm impedance and 0805 footprint. Verify pin compatibility and electrical ratings before substituting.
