DESCRIPTION:
All dimensions in mm typical
Very small metal-can packages
High stability
Low aging
Low power consumption
High shock and vibration resistance
The DS-crystal-series are tubular metal-can packages in the standardized
watch-crystal sizes
∅
2 x 6 mm,
∅
1.5 x 5 mm and
∅
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.
DS26 and DS15 are supplied in plastic-bags (1'000 pcs.)
DS10 is supplied in plastic-bags (200 pcs.)
