Overview
The ACMP-7038-141-T is a two-line surface-mount common mode choke manufactured by Abracon LLC. It features a ferrite core and provides an impedance of 140 ohms at 100 MHz. The component supports a maximum DC current of 9 A with a maximum DC resistance of 10 mohms. It operates within a temperature range of -40°C to +125°C. Physical dimensions are 7 mm in length, 6 mm in width, and 3.8 mm in height.
Feature Summary
- Two-line configuration for differential signal filtering
- Ferrite core construction for high-frequency noise suppression
- Surface mount technology for automated PCB assembly
Applications
- High-speed data line protection
- EMI suppression in communication interfaces
- Common mode noise reduction in electronic circuits
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official Abracon datasheet before integration. Confirm that the physical footprint matches the design layout requirements. Ensure the operating temperature range aligns with the environmental conditions of the final application. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when a compact, two-line filter is required for signals carrying up to 9 A of DC current. The 140 ohm impedance at 100 MHz makes it suitable for suppressing common mode noise in high-frequency applications. Consider the small SMD package size if space constraints are critical. Verify compatibility with the target signal integrity requirements and thermal management strategy.
Part Context
This component belongs to the ACMP-7038 series of common mode chokes from Abracon. The series offers various impedance and current ratings tailored for different filtering needs. The ACMP-7038-141-T specifically targets applications requiring moderate impedance and high current handling in a small form factor.
Replacement Considerations
Direct substitutes include other Abracon ACMP-7038 variants with matching electrical characteristics. Verify impedance, current rating, and physical dimensions when considering alternatives from other manufacturers.
