Procurement Notes
Verify the manufacturer part number against official Pulse Electronics documentation to confirm specifications. Ensure compatibility with design constraints regarding impedance, current rating, and thermal performance before procurement. Cross-reference datasheets for accurate mechanical and electrical parameters.
Selection Notes
Select this component for applications requiring common mode filtering on differential pairs. Consider the 220 Ohm impedance value relative to the target frequency spectrum. Evaluate the 500 mA current rating against the operational load. Confirm that the unshielded construction meets the electromagnetic interference requirements of the final assembly.
Part Context
This component belongs to the BWCU series of compact common mode chokes manufactured by Pulse Electronics. These devices are engineered for space-constrained electronics, offering reliable noise attenuation in small surface-mount packages suitable for modern consumer and industrial electronic designs.
Replacement Considerations
Consult official distributor databases for verified substitute part numbers. Ensure any replacement matches the original impedance, current rating, and physical dimensions to maintain circuit integrity.
