Hi,
I'm working on a high power adjustable DC-DC converter. Because of low frequency (30-60-ish kHz) I have calculated that the inductor I need would be about 150-200uH rated at 30A (ya, i know, it will be large). Do you know a manufacturer that has stuff like that available off-the-shelf? I have shecked typical suspects like Murata, Epcos/TDK, Vishay, Coilcraft, Bourns, TayoYuden and a few others, but they usually don't have anything remotely close to what I need. I'd prefer the manufacturer to be based somewhere in EU, but it's not a hard condition.
I know I can buy the core and some bigass magnet wire (or rather litz wire) and wind that myself or have such inductor suctom made by a specialized company. First solution is time consuming and the second one is expensive and involves long wait time, in addition, the final demand for the component will be about 100pcs/year tops.
