Overview
The TDK ACM2012H-900-2P-T00 is a surface-mount common mode filter designed for high-speed differential signal lines. It features an impedance of 90 Ohms at 100 MHz and supports a rated current of 300 mA with a maximum DC resistance of 190 mOhms. The component operates within a temperature range of -40°C to +85°C and has a compact footprint of 2.0 mm x 1.2 mm x 1.2 mm.
Feature Summary
- Designed specifically for suppressing electromagnetic interference on high-speed differential signal lines.
- Provides effective noise reduction in compact surface-mount packages suitable for space-constrained designs.
Applications
- High-speed differential signal line filtering
- General signal line noise suppression
Procurement Notes
Verify the specific suffix 'T00' against official TDK documentation, as variants like 'T001' or 'T002' may exhibit different electrical ratings such as current handling or voltage tolerance. Confirm RoHS compliance and AEC-Q200 qualification status directly from the manufacturer's datasheet before integration into production schedules.
Selection Notes
Select this component when designing circuits requiring common mode noise attenuation for high-speed data interfaces. Ensure the 300 mA current rating meets the application's peak load requirements. Verify that the 90 Ohm impedance profile aligns with the target frequency spectrum for optimal signal integrity preservation.
Part Context
This part belongs to the TDK ACM series of common mode chokes and filters. The ACM series offers various impedance values and current ratings across multiple package sizes, including 0805, 1008, and larger formats, catering to diverse electronic equipment needs from consumer electronics to automotive applications.
Replacement Considerations
Check for direct substitutes within the ACM2012H series with identical 90 Ohm impedance and 300 mA rating. Cross-reference mechanical dimensions and pin configurations to ensure compatibility with existing PCB footprints without redesigning the layout.
