Description
The 32S12 Series is a micro-miniature,
plastic-molded, surface mountable ver-
sion 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.
Applications & Features
• Very small, compact packaging
• Rugged, plastic-molded design, resistant
to shock and vibration
• Excellent resistance to heat shock and
environmental characteristics
• Ideally suited for automated pick-and-
place assembly environments
• Available on tape and reel
• Ideal for portable applications, time of
day clocks, communication equipment,
pagers, cellular telephones, camcorders,
and micro computers
