Common Mode Chokes Procurement Notes

Verify the specific suffix 'U' against the manufacturer's official documentation to confirm packaging configuration and reel specifications. Ensure that the requested quantity aligns with standard factory pack sizes or cut tape availability. Cross-reference the RoHS compliance status directly with the latest datasheet revision to meet regulatory requirements for your target market.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring multi-line common mode noise attenuation in a minimal footprint. The 120 Ohm impedance rating is appropriate for high-frequency signal lines where moderate attenuation is sufficient. Consider the 140 mA current rating to ensure the component does not saturate under normal operating conditions while maintaining effective filtering performance.
