Common Mode Chokes Procurement Notes

Verify the exact datasheet version when sourcing, as specifications may vary by manufacturing batch or region. Confirm that the supplier provides original Panasonic Electronic Components products to ensure reliability. Check for any specific handling requirements related to the small 0302 package size during assembly. Ensure compatibility with your PCB footprint design before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when space is limited due to its 0302 package size. Choose based on the required 12 ohm impedance at 100 MHz for the target data rate. Consider the low DC resistance feature if power efficiency is critical for the specific interface. Verify that the application involves high-speed digital signals such as USB or HDMI where common mode noise is a primary concern.

Common Mode Chokes Part Context

This part belongs to the Panasonic EXC series of common mode chokes, which are specialized for suppressing electromagnetic interference in high-speed digital communication lines. The series is widely used in consumer electronics and computer peripherals where signal integrity must be maintained in compact form factors.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the EXC series with similar impedance values. Verify that alternative components match the 0302 package dimensions and thermal characteristics. Ensure replacement parts maintain comparable insertion loss and DC resistance specifications for the specific application.
