Overview
The ACM-21-900M-T is a two-line common mode choke from the Abracon ACM-21 series, designed for surface mount applications. It features an impedance of 90 Ohms at 100 MHz and supports a maximum DC current of 400 mA. The component has a maximum DC resistance (DCR) of 300 mOhms and operates within a temperature range of -40°C to +85°C. Housed in a compact 0805 package measuring 2.0 mm x 1.2 mm x 1.2 mm, it utilizes a wirewound ferrite core construction.
Feature Summary
- Compact 0805 surface mount footprint suitable for space-constrained designs
- Wirewound ferrite core construction for effective noise suppression
- Dual-line configuration for differential signal protection
Applications
- Personal computer peripheral interfaces
- Digital video camera (DVC) signal lines
- Set-top box data transmission paths
Procurement Notes
Verify the specific manufacturer part number against official Abracon documentation to ensure accuracy. Confirm that the required impedance and current ratings align with the circuit design specifications before procurement. Check for RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this component when a low-profile 0805 common mode choke is required for high-speed digital signals. Ensure the 400 mA current rating meets the operational requirements of the target application. Verify that the 90 Ohm impedance at 100 MHz provides adequate attenuation for the specific noise frequencies present in the system.
Part Context
This component belongs to the Abracon ACM-21 series of common mode chokes. The series offers various impedance values within a standardized small outline package. These components are engineered to suppress electromagnetic interference in compact electronic devices without occupying excessive board real estate.
Replacement Considerations
Cross-reference with other ACM-21 series variants such as ACM-21-361M-T or ACM-21U-900-T if different impedance characteristics are needed. Ensure any substitute maintains the same 0805 package dimensions and thermal operating range.
