SURFACE-MOUNT CRYSTALS
AG CRYSTALS
7.0mm x 1.5mm x 1.4mm
DESCRIPTION
OUTLINES AND DIMENSIONS
AG crystals are ultra-miniature surface-mount crystals specifically designed
to provide 32.768kHz for real-time clocks and 75kHz frequencies. With
their ultra-small size and rugged construction they are ideal for batterypowered, hand held miniature equipment applications.
