Procurement Notes
Verify the specific part number suffix against official manufacturer documentation to ensure correct specifications. Confirm that the component meets the required AEC-Q200 qualification status for your target application. Cross-reference datasheet parameters such as inductance and current ratings with system design requirements before procurement.
Selection Notes
Select this component when space-constrained automotive designs require effective EMI suppression on signal lines. The 1210 footprint allows for compact PCB layouts while maintaining robust shielding characteristics. Ensure the 150 mA current rating aligns with the operational load of the protected circuit to prevent saturation.
Part Context
This component belongs to the SRF3225TAC series of small-sized, automotive-grade common mode chip inductors. The series utilizes a double-wound configuration on a ferrite core to deliver high impedance and low radiation. These components are engineered to suppress electromagnetic interference entering or leaving electronic systems in demanding environments.
Replacement Considerations
Consult official Bourns documentation for verified substitute part numbers within the same series or family. Do not assume interchangeability with other manufacturers' components without validating pinout, electrical parameters, and physical dimensions against the original specification sheet.
