Overview
The Abracon ACMP-9050-102-T is a surface-mount common mode choke designed for power line noise suppression. It features a ferrite core and supports a maximum DC current of 4 A with a maximum DC resistance of 13 mOhms. The component exhibits an impedance of 1 kOhm at 100 MHz. Its physical dimensions are 9 mm in length, 7 mm in width, and 5 mm in height. It operates reliably within a temperature range of -40°C to +125°C.
Feature Summary
- Utilizes a ferrite core material for effective high-frequency noise attenuation
- Designed for surface mount PCB integration with horizontal pad configuration
- Supports high current handling capabilities suitable for power line applications
Applications
- Power supply input filtering
- DC-DC converter noise suppression
- General purpose EMI filtering on power lines
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure correct impedance and current ratings. Check RoHS compliance status if required by your assembly specifications. Ensure the footprint matches the 9x7mm outline before finalizing procurement.
Selection Notes
Select this component when a 1 kOhm impedance at 100 MHz is required for common mode noise reduction. Ensure the circuit current does not exceed 4 A to prevent saturation or excessive heating. Verify that the 5 mm height fits within the mechanical constraints of the enclosure. Consider the 13 mOhm DCR impact on overall system efficiency.
Part Context
This component belongs to the ACMP series of power common mode chokes from Abracon. These devices are engineered for compact designs requiring robust EMI performance. The series offers various impedance and current ratings to suit different power levels. The ACMP-9050-102-T specifically targets applications needing moderate current handling with standard impedance characteristics.
Replacement Considerations
Direct substitutes include the ACMP-Q9050-152-T for higher current requirements (4.5 A) and the ACMP-5025-102-T for smaller footprint needs (5x4.8mm). Verify pinout compatibility and thermal performance before swapping. Ensure the replacement maintains the same 1 kOhm impedance specification.
