HCTC & HCTI Design Kit High Current Toroidal Inductors & Chokes This new High Current Toroidal Inductor and Choke design kit is filled with Signals most popular HCTI and HCTC values to make circuit design easier. The HCTI series are vertically oriented for optimization of PCB layout, have self-shielding for low magnetic flux radiation, have a distributed air gap for high energy storage, have high efficiency through reduced core loss, and operate down to lower temperatures compared to traditional laminated inductors. The HCTC series has vertical PCB header plate mounting and has a wide range of inductance and current ratings which provides optimal board layout. This allows Compatibility Guide cooler running power supplies to be incorporated into multiple applications.
