Abstract
A clip for surface-mounting a coupled-dual resonator crystal to a circuit board includes an elongated housing shaped complementary to the housing of the crystal and having an opening along a side for receiving the crystal. A tab spaces first and second shielding portions which overlie the end of the crystal housing. A first shield portion engages the middle ground terminal of the crystal shielding the input and output terminals, while the second shield extends from the first shield to overlie the output terminal, likewise shielding it from the input terminal. Distal portions of the input, output and common terminals, together with pads at the opposite end of the clip, mount the clip mechanically to the surface of a circuit board.
