WE-MAIA SMD Metal Alloy Power Inductors Würth Elektronik WE-MAIA SMD Metal Alloy Power Inductors represent the smallest wound inductors with AEC-Q200 qualification. These Würth SMD metal alloy power inductors provide 50% higher switching controller efficiency due to high saturation current (ISAT) and low DC resistance (RDC). Würth Elektronik WE-MAIA features a pre-pressed case that prevents material cracks in the core and reduces the stray field. WE-MAIA series is magnetically shielded and ensures more effective process controlling due to a higher level of automation.
