A crystal controlled clock oscillator resin encapsulated in a surface mount device (SMD) package incorporates on a lead frame a crystal oscillator, an integrated circuit, a power supply filter capacitor and, optionally, a feedback resistor. In the fabrication of the device, resin is injected at a position and in a direction relative to the components so as to minimize disturbance of the lead frame and the components mounted thereon.
