Overview
The ACMP-Q3226-242-T is a surface-mount common mode choke from the Abracon ACMP-Q series, designed for automotive power applications. It features a ferrite core and unshielded construction with dimensions of 3.2mm x 2.5mm x 2.35mm. The component provides an impedance of 2.4 kOhms at 100 MHz and supports a maximum DC current of 640 mA. Its maximum DC resistance is 300 mOhms. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Designed specifically for automotive power circuit protection
- Utilizes a ferrite core material for effective noise suppression
- Compact surface-mount footprint suitable for space-constrained PCBs
Applications
- Automotive power line filtering
- Common mode noise suppression in vehicle electronics
- Protection of sensitive automotive components from EMI
Procurement Notes
Verify the specific suffix 'T' indicates the tape and reel packaging configuration as listed by distributors. Confirm that the part meets AEC-Q200 automotive qualification standards if required for your specific application environment. Ensure the 640mA current rating aligns with your circuit's peak load requirements to prevent saturation.
Selection Notes
Select this component when a compact, automotive-grade common mode choke is needed for low-current power lines. The 2.4 kOhm impedance at 100 MHz offers targeted attenuation for high-frequency noise. Consider the 300 mOhm DCR impact on voltage drop if efficiency is critical. Compare against higher current variants in the ACMP-Q series if system loads exceed 640 mA.
Part Context
This part belongs to the Abracon ACMP-Q series of automotive common mode chokes. These components are engineered to meet rigorous automotive reliability standards. The series offers various impedance and current ratings to suit different power rail requirements, providing a standardized solution for electromagnetic interference mitigation in modern vehicles.
Replacement Considerations
Direct substitutes include other ACMP-Q series parts with similar impedance and current ratings, such as ACMP-Q3226-102-T or ACMP-Q3226-402-T, provided they fit the same mechanical footprint. Verify that any replacement maintains the same AEC-Q200 qualification and operating temperature range.
