Procurement Notes
Verify the specific manufacturer part number against official Bourns documentation to ensure accuracy. Confirm that the impedance value and current ratings match the design requirements. Check for RoHS compliance status as indicated in the datasheet. Ensure the package dimensions align with the PCB footprint specifications before procurement.
Selection Notes
Select this component based on its 260 Ohm impedance at 100 MHz and 300 mA current handling capability. Consider the 2012 metric package size for space-constrained designs. Evaluate the operating temperature range of -55°C to +125°C for environmental suitability. Compare DC resistance values to minimize power loss in the application circuit.
Part Context
This component belongs to the Bourns SRF2012A series of common mode chip inductors. These devices are designed for high-frequency noise suppression in compact electronic systems. The series offers various impedance values while maintaining a consistent small form factor suitable for modern surface mount assembly processes.
Replacement Considerations
The SRF2012-361YA is a related variant within the same series offering different impedance characteristics. Other models in the SRF2012A family may serve as substitutes if electrical parameters such as impedance and current rating are compatible with the original design requirements.
