SURFACE MOUNT CRYSTAL SERIES HCX-7S
DESCRIPTION
VTM offer a surface mount crystal in a standard 7mm by 5mm package.
The frequency range is 9.8304 to 100 MHz. The standard operating
temperature range is -10°C to 60°C, although an extended range of
-20°C to +70°C can be manufactured. These crystals can be IR reflowed,
and typical applications are notebook computers, telecommunications
equipment and modems. The crystals are supplied taped and reeled on
178mm diameter reels containing 1000 pieces.
