Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this part may be discontinued. Ensure storage conditions meet moisture sensitivity level requirements prior to reflow soldering.

Selection Notes

Select this component when space constraints require a 0402 footprint and moderate current handling up to 350 mA is sufficient. Evaluate thermal performance against the specified operating temperature range. Compare impedance characteristics at target frequencies against alternative ferrite beads to ensure effective noise attenuation.

Part Context

This component belongs to the BK series of multilayer chip bead inductors manufactured by Taiyo Yuden. These components are engineered for high-density applications requiring reliable electromagnetic interference suppression in small form factors.

Replacement Considerations

Cross-reference with other 0402 ferrite beads offering similar 47 Ohm impedance and 350 mA current ratings. Verify physical dimensions and terminal configurations match existing board layouts before substitution.
