Common Mode Chokes Procurement Notes

Verify the specific suffix XK2L against the official Murata datasheet to confirm packaging details and availability. Ensure the ordered part matches the exact electrical specifications required for the target circuit design. Cross-reference the manufacturer part number with authorized distributors to prevent counterfeit components. Confirm RoHS and REACH compliance status if mandated by regional regulations.

Common Mode Chokes Selection Notes

Select this component when a 100 μH inductance value is required for common mode noise reduction in compact spaces. The 1812 footprint offers a balance between performance and board area efficiency. Consider the 200 mA current rating to ensure the component does not saturate under normal operating conditions. Verify that the -40 °C to 125 °C temperature range meets the environmental requirements of the application.

Common Mode Chokes Part Context

This component belongs to the DLW43S series of thin-film or wirewound common mode chokes designed for automotive and industrial applications. The series is characterized by its ability to handle high-frequency noise while maintaining a low profile. The DLW43SH101XK2 specifically targets applications requiring robust EMI suppression in constrained PCB layouts.

Common Mode Chokes Replacement Considerations

Consult the official Murata replacement guide for direct equivalents. Verify pin compatibility and electrical parameters before substituting with other manufacturers' parts.
