Description
The 32S12 Series is a micro-miniature,
plastic-molded, surface mountable version of the 32.768 kHz tuning fork-type
quartz crystal. The crystal is housed in a
rugged, high-temperature tubular holder,
then mounted to a leadframe and injection
molded into its plastic carrier. Two sizes
and two lead connection configurations
are available.
