Abstract
An electrical device is provided with a compressible intermediate layer between an active electrical component and an exterior protective coating. The intermediate layer includes a substantially solid filler material in a resin binder material. The compressive intermediate layer helps to protect a fragile electrical component from stresses resulting from possible shrinkage of the protective coating during curing or hardening, from expansion or contraction of the protective coating during temperature cycling and from the adhesive nature of the protective coating.
