D/M Stelschroef: B65679E0002X022 (B65679E0003X022 bestaat ook, maar het kernmateriaal hierop is iets dunner. De air-gap kan dan dus niet volledig gesloten worden, en aangezien de originele spoel met 485 windingen een zelfinductie van maximaal 237mH heeft, moet deze, met een kern met een A_L van 1000nH, wel volledig gesloten kunnen worden.)
