These two new CST series are based on different ferrite cores. The first series is compatible with existing designs based on an EE5 core. It features a footprint of only 8.33 x 7.11mm² and an insertion height of 5.08mm. The DC resistance of the primary winding is 0.8mΩ in all types of this series. These transformers are designed for a maximum current of 20A and a test voltage of 500V. Depending on the transfer ratio, the series covers inductances between 80 and 3000μH.
