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.)
