Procurement Notes
Verify the specific suffix 'YA' against the manufacturer's official datasheet to confirm terminal plating and packaging specifications. Ensure the selected component meets the required impedance tolerance and current handling capabilities for the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when a compact common mode choke with 260 Ohm impedance at 100 MHz is required. Consider the 300 mA current rating and 400 mOhm DCR limits to ensure compatibility with the power budget and signal integrity requirements of the application circuit.
Part Context
This part belongs to the Bourns SRF2012A series of common mode chip inductors. The series offers various impedance values tailored for different noise suppression needs while maintaining a consistent 2012 metric package size for standardized PCB footprint integration across multiple product lines.
Replacement Considerations
Consult official substitution guides for equivalent parts with matching 260 Ohm impedance and 300 mA rating. Verify pinout compatibility and physical dimensions before replacing to ensure seamless integration without redesigning the PCB layout.
