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.)

Very small metal-can packages

High stability

Low aging

Low power consumption

High shock and vibration resistance

ELECTRICAL CHARACTERISTICS

1) Other load capacitances on request.

2) Tighter and wider frequency tolerances on request.
