Procurement Notes
Verify the manufacturer designation as Max Echo Technology Corp. when sourcing this component. Confirm that the part number EOWS201212M221 corresponds to the specified 220 Ohm impedance and 300 mA current rating. Ensure the surface mount package type matches the design requirements. Cross-reference technical specifications with official documentation to guarantee compatibility with the intended circuit application.
Selection Notes
Select this component based on its specific impedance characteristics at 100 MHz and its current handling capability of 300 mA. The low DC resistance of 400 mOhm minimizes power loss in the signal path. Consider the physical dimensions and mounting style required for the target PCB layout. Evaluate the noise suppression performance against the electromagnetic interference environment of the final product.
Part Context
Max Echo Technology Corp. specializes in multilayer chip inductors, employing professional magnetic materials and low-temperature co-firing processes. The EOWS series represents their surface mount common mode choke offerings. This component integrates precision winding technology to achieve consistent electrical performance. The company positions itself as a provider of high-quality passive components for modern electronics manufacturing.
Replacement Considerations
No public substitute part numbers are confirmed for this specific model. Verify compatibility with alternative components by matching the 220 Ohm impedance at 100 MHz, 300 mA current rating, and 400 mOhm DCR. Ensure any replacement maintains the same surface mount footprint and two-line configuration.
