Toroidal units are typically used in applications in which there are size constraints or other sensitive electrical parameters that prevent the use of a standard E-I magnetic. V&F can produce toroids both domestically and internationally in various sizes ranging from PC Board Level component size up to 10+ kVA (11” Outside Diameter). V&F’s C-Core Product Line allows for the use of high grade materials (M4 and Better) in an efficient and repeatable manner thus reducing high labor costs and also allowing for easy to adjust reactive magnetics. V&F has an extensive supply chain, both domestically and internationally to allow standard and custom C-Core Configurations. Our C-Core Reactive Magnetics are primarily used in high frequency, high power reactor and choke applications which require inductance tuning and high grade core materials to address high energy harmonic content.
