Overview
The ACM-31-900M-T is a two-line common mode choke manufactured by Abracon LLC, designed for surface mount applications. It features an impedance of 90 Ohms at 100 MHz and supports a maximum DC current of 370 mA. The component has a maximum DC resistance (DCR) of 300 mOhms and a rated DC voltage of 50V. It operates within a temperature range of -40°C to +85°C. The physical dimensions are 3.00mm in length, 1.60mm in width, and a maximum height of 2.00mm, housed in a horizontal 4-pin package.
Feature Summary
- Provides common mode noise suppression for signal lines with a 90 Ohm impedance characteristic at 100 MHz.
- Supports high-speed data transmission lines while maintaining low DC resistance to minimize signal loss.
- Utilizes a compact horizontal surface mount footprint suitable for space-constrained printed circuit board designs.
Applications
- High-speed data interface protection
- Signal line filtering in electronic devices
- Common mode noise reduction in communication circuits
Procurement Notes
Verify the specific part number ACM-31-900M-T against official Abracon documentation to ensure accuracy. Confirm that the required electrical parameters, including the 370 mA current rating and 90 Ohm impedance, align with the design specifications. Check for RoHS compliance status and moisture sensitivity level requirements before integration into the manufacturing process.
Selection Notes
Select this component when a low-profile, two-line common mode choke is required for high-frequency noise suppression. Ensure the application current does not exceed 370 mA to prevent saturation or excessive heating. Verify that the 50V DC voltage rating meets the circuit requirements. Consider the 3.00mm x 1.60mm footprint for PCB layout compatibility.
Part Context
This component belongs to the ACM-31 series of common mode chokes from Abracon LLC. The series offers various impedance and current ratings tailored for different signal integrity needs. The ACM-31 series is characterized by its small surface mount package and consistent performance across a wide temperature range, making it suitable for modern electronic assemblies requiring efficient noise filtering.
Replacement Considerations
Consult official Abracon documentation for verified substitute part numbers within the ACM-31 series or other compatible families. Ensure any replacement matches the critical electrical parameters, such as impedance at 100 MHz and maximum DC current, as well as the physical footprint and pin configuration.
