Procurement Notes
Verify the complete part number including suffixes against official manufacturer documentation to ensure exact specification matching. Confirm AEC-Q200 certification status if automotive compliance is required. Check datasheet for specific impedance tolerance and thermal characteristics relevant to your design environment.
Selection Notes
Select this component when designing circuits requiring low insertion loss and high common mode rejection in small form factors. Ensure the operating current does not exceed the 350mA rating to prevent saturation. Consider the 160 Ohm impedance value at 100 MHz for target noise frequency attenuation requirements.
Part Context
Walsin Technology Corporation specializes in passive components, including capacitors, resistors, and RF elements. This common mode choke belongs to their series of magnetic components designed for signal integrity and electromagnetic interference reduction in modern electronic assemblies.
Replacement Considerations
Consult official substitution guides for equivalent parts with matching impedance, current ratings, and package dimensions. Verify that any alternative maintains AEC-Q200 qualification if used in automotive contexts.
