Procurement Notes
Verify the specific suffix 'YA' against the manufacturer's official datasheet to confirm material composition and compliance status. Ensure the selected variant matches the required impedance tolerance and thermal characteristics for the target application environment.
Selection Notes
Select this component when space-constrained surface mount solutions are required for signal line protection. Consider the 300mA current rating and 400mOhm DCR limits to ensure compatibility with the target circuit's power budget and signal integrity requirements.
Part Context
This part belongs to the SRF2012 series of common mode chip inductors manufactured by Bourns Electronic Solutions. The series offers compact footprints suitable for dense PCB layouts, providing effective noise suppression for sensitive electronic components in modern devices.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify that any substitute maintains identical impedance curves, current ratings, and physical dimensions to ensure seamless integration without redesigning the host circuit board.
