Procurement Notes

Verify the specific part number suffix against official Bourns documentation to ensure correct electrical characteristics. Confirm that the required inductance and current ratings align with the circuit design specifications before procurement. Check for any recent product change notifications regarding manufacturing updates or material substitutions.

Selection Notes

Select this component when a 3 mH inductance value is required for common mode noise reduction in space-constrained designs. Ensure the operating current does not exceed 350 mA to prevent saturation. Consider the 330 mOhm DC resistance impact on voltage drop within the specific application circuit.

Part Context

This component belongs to the Bourns SRF1006 series of common mode chokes. The series offers various inductance values tailored for different filtering requirements while maintaining a consistent small footprint suitable for automated surface mount assembly processes.

Replacement Considerations

Consult official Bourns substitution guides for verified alternatives. Cross-reference inductance, impedance, and current ratings with other SRF1006 variants if exact matches are unavailable.
