Würth Elektronik's WE-DD series is one of the industry‘s most used coupled inductor families. The great advantages of this family are the flexibility in size. The WE-DD series offers two standard footprints: 7x7mm and 12x12 mm, each with different heights to find the right part by taking maximum heights, max currents or targeted DCR resistances in measurement. The WE-DD series is available with a crossed, as well as a straight, pin layout. An overview is shown on the next slide. Würth Elektronik's WE-DD series has maximum current handling capabilities of 8.6A DC current and up to 18A in saturation current. Besides in SEPIC converters, the WE-DDs can also be used in CUK topologies, non-isolated flyback applications and switching regulators with a second, unregulated output voltage.
