DESCRIPTION:
The DS-crystal-series are tubular metal-can packages in the standardized
watch-crystal sizes DS26 = ∅ 2 x 6.0 mm, DS15 = ∅ 1.5 x 5.0 mm and
DS10 = ∅ 1 x 4.3 mm for thru-hole applications.
Within the package is a high-quality tuning fork quartz crystal resonator,
manufactured with precision high-volume photolithographic process and
operating in the fundamental mode at 32.768 kHz.
Due to highly automated, large-volume production, the DS-crystal-series
is very price competitive and ideal for any consumer application.
DS Products are supplied in plastic-bags (1'000 pcs.)
