Procurement Notes
Verify the specific suffix codes against official manufacturer documentation to ensure correct impedance and current ratings. Confirm AEC-Q200 compliance requirements match your application standards. Check for RoHS and REACH regulatory status prior to procurement. Ensure storage conditions align with moisture sensitivity levels defined in the datasheet.
Selection Notes
Select this component when designing circuits that require precise common mode noise attenuation at 100 MHz. Evaluate the 220 mA current rating against peak load requirements to prevent saturation. Consider the 2012 footprint dimensions for PCB layout constraints. Verify thermal performance under continuous operating conditions.
Part Context
This component belongs to Walsin's passive filter portfolio, specifically designed for electromagnetic interference mitigation. It utilizes thin-film or thick-film technology typical for surface mount chokes. The product line targets industries demanding reliable noise control in compact form factors.
Replacement Considerations
Consult official substitution lists for equivalent impedance and current ratings. Verify pin compatibility and mechanical dimensions before replacement. Ensure environmental qualifications match original specifications.
