The ACMS-0605U-250-T is a surface-mount common mode choke from Abracon LLC, designed for high-frequency noise suppression in compact electronic assemblies. This component features a monolithic ceramic construction within a miniature 0202 (0.65 x 0.50 mm) package. It provides a common mode impedance of 25 ohms at 100 MHz and supports a maximum DC current rating of 50 mA. The device exhibits a maximum DC resistance of 3.5 ohms per line, ensuring minimal signal attenuation while effectively filtering electromagnetic interference.
Verify the specific impedance value and DC current rating against the latest official datasheet before procurement. Confirm that the 0202 package dimensions align with the PCB land pattern requirements. Ensure the selected variant matches the required operating temperature range for the target application environment to guarantee long-term reliability.
Select this component when space constraints are critical due to its ultra-small 0202 footprint. Choose based on the required impedance level at the target noise frequency and the maximum DC current expected in the circuit. Consider the low DC resistance characteristic for applications where signal power loss must be minimized alongside noise reduction.
This part belongs to the ACMS-0605U series of miniature common mode chokes manufactured by Abracon LLC. The series utilizes advanced multilayer ceramic technology to achieve high performance in a significantly reduced volume compared to traditional wire-wound alternatives. These components are engineered for modern portable devices requiring efficient EMI management without compromising board real estate.
