Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm part status as discontinued at major retailers like DigiKey before procurement planning. Request official datasheets from Schott Corporation to validate specifications against design requirements. Ensure storage conditions meet manufacturer guidelines to preserve component integrity prior to assembly.

Selection Notes

Select this component when surface mount common mode filtering is required for two-line circuits. Consider the 1 Ohm DCR specification for power loss calculations in the target application. Evaluate physical footprint compatibility with existing PCB layouts. Verify that the noise suppression characteristics align with the electromagnetic interference environment of the end-use device.

Part Context

This component belongs to the common mode choke category within Schott Corporation's electronic filter portfolio. It serves as a passive filtering element used to attenuate high-frequency noise signals common to both lines in a differential pair. The surface mount designation indicates its suitability for automated placement machines during manufacturing.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is listed as discontinued at major distributors, alternative sourcing strategies must be pursued. Engineers should consult Schott Corporation directly for potential obsolescence management options or equivalent replacements.
