Common Mode Chokes Procurement Notes

Verify the specific part number ET3542-056 against official Triad Magnetics documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with required safety certifications such as UL, CSA, or IEC for your target market. Confirm that the through-hole pin configuration matches your PCB layout requirements before finalizing procurement decisions.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring 8.1 mH of common mode inductance at 10 kHz with a 3A current capacity. Consider the 120 milliohm DCR for efficiency calculations and verify that the 250V AC rating meets system voltage requirements. Evaluate the vertical through-hole form factor against available board space constraints.

Common Mode Chokes Part Context

This component belongs to the ET series of common mode chokes manufactured by Triad Magnetics. The series offers various inductance values and current ratings tailored for power line filtering. The ET3542-056 specifically addresses applications needing moderate inductance with high current handling capabilities in a robust through-hole package.

Common Mode Chokes Replacement Considerations

Consult Triad Magnetics documentation for direct substitutes within the ET series. Verify that alternative parts match the 8.1 mH inductance, 3A current rating, and 120 milliohm DCR specifications. Ensure physical dimensions and pin configurations remain compatible with existing PCB layouts.
