Feature Summary
- Provides signal line filtering for differential data pairs
- Utilizes wirewound ferrite core construction
- Designed for high-density surface mount assembly
Applications
- High-speed digital signal line protection
- USB interface circuit filtering
- HDMI data path noise suppression
Procurement Notes
Verify the specific current rating against official datasheets, as sources indicate variations between 280 mA and 450 mA for this part number. Confirm RoHS3 compliance and MSL level 1 status during procurement. Ensure the supplier provides valid traceability documentation matching the manufacturer's specifications.
Selection Notes
Select this component for applications requiring moderate impedance attenuation at 100 MHz. Compare the 450 mA current rating against circuit requirements to prevent saturation. Evaluate the physical footprint compatibility with existing PCB layouts before finalizing the design choice.
Part Context
This component belongs to the ACM-21 series of chip wire wound common mode chokes manufactured by Abracon Corporation. The series offers various impedance options tailored for different frequency attenuation needs while maintaining a standardized small outline package format for automated placement.
Replacement Considerations
ACM-21-361M-T: Higher impedance (360 Ohms) but lower current rating (280 mA).
FAQ
What is the withstand voltage specification?
The component has a specified voltage withstand capability of 125V.
Is the device shielded?
No, the ACM-21-300M-T is an unshielded common mode choke.
