Procurement Notes

Verify the specific suffix 'YH' against official Bourns documentation to confirm exact specifications, as ordering codes may denote variations in packaging or compliance status. Ensure the procurement channel provides valid traceability and authenticity guarantees for automotive-grade components. Cross-reference the part number with the latest datasheet to confirm RoHS3 compliance and AEC-Q200 ratings before finalizing orders.

Selection Notes

Select this component when designing circuits requiring precise common mode noise attenuation for low-current signal lines. The 22 µH inductance value is optimal for suppressing interference in the specified frequency range without significantly impacting signal integrity. Consider the 310 mA current rating to ensure the component does not saturate under normal operating conditions. Verify that the surface-mount package fits the available board space and soldering profile requirements.
