Resilient epoxies applied to magnetic components

Developments in resilient epoxy resin systems have a marked influence upon the selection and application of encapsulants for magnetic components. The designer is prone to think in terms of a resilient insulating material which accommodates the mechanical and thermal stresses arising during the performance of magnetic circuits. Resiliency in an epoxy electrical insulating material is not gained without sacrificing some other properties. It may be necessary to compromise some physical or chemical resistance requirements when selecting the final material in order to achieve optimum combinations of physical and electrical properties. There are numerous resilient epoxy systems from which to choose and for a given set of performance requirements, an optimum material may be selected.
