High Energy Storage Chokes from The Premo Group

High energy storage chokes are used in applications requiring very high efficiencies (99%+ in some cases), excellent inductance stability over temperature and very high current storage capabilities.

New, modern core materials are now available to manufacturers that allow for smaller form factor components while maintaining high current and high inductance with low resistances which benefit thermal performance.  Premo utilizes these materials throughout their product line which result in technologically advanced, high performance solutions.
