1. A surface mountable ultracapacitor device, the device comprising:
a package including sidewalls extending in a direction generally perpendicular to a base to define an upper end wherein an interior cavity is defined between an inner surface of the base and the sidewalls;
first and second conductive members disposed on the inner surface of the base;
first and second external terminations on the outer surface of the base and electrically connected to the first and second conductive members, respectively;
an ultracapacitor positioned within the interior cavity and including a housing and an electrode assembly and electrolyte within the housing, the ultracapacitor including first and second leads electrically connected to the first and second conductive members, respectively;
a resin provided within the interior cavity and encapsulating at least a portion of the ultracapacitor; and
one or more vents extending through the resin, wherein 30% or less of the length of the one or more vents extends from a surface of the resin.
