Abstract
A capacitive device having first and second electrical contacts and being configured for leadless attachment within electrical circuitry. The capacitive device has at least one layer of electrically and thermally insulative material covering all sides of the device; a plurality of access passages for accommodating electrical access to the first and second electrical contacts of the capacitive device through the at least one layer of thermally insulative material, each of which access passages is configured to limit thermal communication to the first and second electrical contacts; and contact pads associated with the first and second electrical contacts of the capacitor for effecting electrical contact through the access passages, which contact pads fill and extend a distance beyond the limits of each of the access passages to increase electrical contact area for the first and second electrical contacts accessible from without the at least one layer of thermally insulative material.
