Overview
The ACM-21-361M-T is a two-line common mode choke manufactured by Abracon LLC, designed for surface mount applications. It features an impedance of 360 Ohms at 100 MHz and a maximum DC current rating of 280 mA. The component has a maximum DC resistance (DCR) of 400 milliohms per line and operates within a temperature range of -40°C to 85°C. Its physical dimensions are 2.00 mm in length, 1.20 mm in width, and a maximum height of 1.40 mm. The device utilizes a horizontal package with four PCB pads.
Feature Summary
- Chip wire wound construction on a ferrite base for signal line interference suppression
- Compact surface mount design suitable for high-density circuit layouts
- Effective attenuation of asymmetric interferences across low-frequency ranges
Applications
- Signal line filtering in electronic circuits
- Suppression of asymmetric electromagnetic interference
- Common mode noise reduction in data transmission lines
Procurement Notes
Verify the specific ordering suffix and packaging configuration against official Abracon documentation before procurement. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Ensure compatibility with standard surface mount reflow soldering profiles. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.
Selection Notes
Select this component when space constraints require a small footprint common mode choke for signal integrity protection. The 280 mA current rating suits low-power signal lines rather than high-current power rails. Consider the 360 Ohm impedance specification at 100 MHz to ensure adequate noise attenuation for the target frequency spectrum. Verify thermal performance within the specified operating temperature range during system integration.
Part Context
This component belongs to the ACM-21 series of chip wire wound common mode chokes from Abracon LLC. The series offers various impedance and current ratings in a standardized compact package. These devices are engineered for signal line applications where minimal board space is available. The ACM-21 series provides consistent performance for suppressing common mode noise in sensitive electronic interfaces.
Replacement Considerations
Consult official Abracon documentation for verified substitute part numbers within the ACM-21 series or equivalent product lines. Ensure any replacement matches the required impedance, current rating, and physical dimensions. Verify that alternative components maintain the same mounting configuration and electrical characteristics for direct interchangeability.
