Procurement Notes

Verify the complete part number including the suffix to ensure correct inductance and current ratings. Confirm that the through-hole footprint matches the target PCB layout dimensions. Check operating temperature specifications against environmental conditions. Ensure compliance with relevant regional safety standards for the intended application market.

Selection Notes

Select this component when high inductance values are required for significant noise attenuation in single-phase AC circuits. Consider the physical size constraints due to the ring core structure. Evaluate the current rating against peak load requirements to prevent saturation. Compare alternative series options if lower profile or different mounting styles are necessary.
