The ACM0439CI is a surface-mount common mode choke manufactured by Allied Components International. It features two lines with an inductance of 100 µH measured at 10 kHz and a maximum DC resistance of 80 mΩ. The component supports a maximum current rating of 1.5 A and operates within an industrial temperature range of -40°C to +85°C.
Verify the manufacturer designation as Allied Components International or Hitech Semiconductor Co., Limited, as sources vary. Confirm the package type is SMD and validate the 1.5A current rating against specific datasheet revisions before integration into final designs.
Select this component for applications requiring compact surface-mount filtering solutions. Ensure the circuit environment stays within the -40°C to +85°C operational limits. Verify that the 100 µH inductance value meets the specific frequency requirements for noise suppression in the target application.
Allied Components International specializes in custom and standard magnetic components. This part belongs to their common mode filter series, designed for commercial and industrial markets including test equipment and power supplies.
