Common Mode Chokes Procurement Notes

Verify the specific datasheet version before procurement to ensure compatibility with your design requirements. Confirm that the through-hole footprint matches your PCB layout exactly. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the 400mA current rating meets the operational demands of your target application without saturation.

Common Mode Chokes Selection Notes

Select this component when a low-profile, through-hole solution is preferred over surface mount alternatives. Consider the 1.7 Ohm DCR impact on voltage drop in low-voltage circuits. Evaluate the 400mA limit against peak load currents to prevent performance degradation. Compare physical dimensions against available board space to ensure proper fitment during assembly.

Common Mode Chokes Part Context

This component belongs to Pulse Electronics' FE2X series of common mode chokes. The series offers various current ratings and inductance values tailored for different noise suppression needs. The FE2X47-4-2NL specifically targets applications requiring moderate current handling with a compact through-hole profile, bridging the gap between high-current industrial chokes and low-current signal filters.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the FE2X series with similar current and resistance specifications. Verify pinout compatibility if replacing in existing designs. Ensure mechanical height constraints are met by alternative components. Consult manufacturer cross-reference lists for verified equivalent parts.
