1. A surface mountable crystal package, comprising:
- a proximal base including an inner, middle and outer section having connecting metalization for providing an electrical path;
the inner section comprises a dielectric material and has a substantially oblong receptacle defined by two aperture sections connected with a channel being substantially complementarily configured to receive at least a proximal portion of a crystal resonator;
a distal cap having an inner face, an outer face and a distal conductive portion;
a sleeve having a distal portion and a proximal portion, the distal portion being connected to the distal cap and the proximal portion being connected to the proximal base; and
the inner section of the proximal base being configured to at least partially be received in the sleeve.

Abstract
A surface mount crystal package (10) receptacle mounting adapted to canti-leverably receive a piezoelectric element. The surface mount crystal package (10) is configured to hermetically enclose a crystal resonator (19) or crystal filter mounted in a proximal base (12) in a cantilever fashion. This package (10) is hermetically sealed in the proximal base 12, a distal cap (14) and sleeve (16). The package (10) is adapted to improve and faciliate surface mounting, provide a low cost and automatable assembly, and provide a low-stress mounting of a piezoelectric element in a simplified and portable design.
