Overview
The TDK ACM2012D-900-2P-T00 is a surface-mount common mode filter designed for high-speed differential signal lines, including DVI and HDMI interfaces. It features a 90 Ohm impedance at 100 MHz with a maximum DC resistance of 300 mOhms. The component supports a rated current of 300 mA and operates within a temperature range of -40°C to +85°C. Its compact 0603 (1608 metric) package dimensions are 1.6 mm x 0.8 mm x 1.0 mm max.
Feature Summary
- Engineered specifically for suppressing electromagnetic interference in digital video interfaces such as DVI and HDMI.
- Provides effective common mode noise attenuation while maintaining signal integrity on high-speed differential pairs.
- Utilizes a compact surface-mount footprint suitable for space-constrained portable electronic designs.
Applications
- DVI interface signal line filtering
- HDMI interface signal line filtering
- High-speed differential data transmission lines
Procurement Notes
Verify the specific suffix against official TDK documentation to confirm pin configuration and packaging type. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design. Cross-reference the manufacturer's latest datasheet to confirm availability and compliance status before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring noise suppression for low-voltage high-speed digital video signals. The 90 Ohm impedance value is optimized for typical characteristic impedances found in DVI and HDMI standards. Consider the 300 mA current rating to ensure adequate headroom for the specific application's power requirements without saturation.
Part Context
This part belongs to the TDK ACM-D series, which specializes in common mode filters for digital video applications. Unlike general-purpose signal filters, this series is tuned for the specific frequency responses and impedance matching requirements of modern display interfaces. It complements other ACM components by offering specialized solutions for high-bandwidth data transmission protection.
Replacement Considerations
Direct substitutes include the ACM2012D-900-2P-T001 or ACM2012D-900-2P-T002 if packaging variations are acceptable. Verify that any replacement maintains the 90 Ohm impedance at 100 MHz and fits within the same mechanical envelope constraints.
