WATCH CRYSTALS IN WIDE RANGE
OF SURFACE MOUNT PACKAGES
Pittsford, NY:
Saelig now offers RoHS-compatible watch crystals housed in a wide range of
surface mount package styles for use in a variety of applications.
The crystals all feature a nominal frequency of 32.768kHz making them ideal for
use in real time clock (RTC) applications with calibration tolerance of ±20ppm
as standard on most devices (±50ppm standard on AG and FC series parts with
±20ppm also available).
Package sizes include 6 x 2mm, 8.7 x 3.8mm, 10.4 x 4mm, 7 x 1.5mm, 5 x 1.9mm and
ultra-miniature 3.2 x 1.2mm. Low power consumption types are available for
portable, battery-powered applications while low cost crystals manufactured in
epoxy resin are suitable for mass-market devices.
Typical specifications include maximum drive levels of 1uW, aging of ±3ppm
maximum in first year, load capacitance of 12.5pF (7pF available on some
models) and operating temperature range from -40 to +85 deg C (-55 to +125 deg C
storage temperature range).
Sourced from one Europe’s largest designer and manufacturer of quartz crystals
and oscillators, Euroquartz’s surface mount watch crystals are supplied in
standard EIA 16mm tape and reel packaging and are suitable for reflow soldering
(10s maximum at 235 deg C or 10s maximum at 260 deg C twice or <230 deg C for
180s).
