At 3.2 x 1.5 mm and a 0.9 mm profile, this is the smallest miniature watch crystal available. It is made for tight quarters, such as in portable or handheld devices. It has a frequency of 32,768 kHz, and the surface mount device offers a standard 12.5 pF load capacitance in the FX135A model, and an optional 9 pF capacitance in the FX135B. With a standard operating temperature of -40 to 85C (-40 to 185F), it has a frequency stability of -0.045 ppm/( C )2 and a frequency tolerance of +/-20 PPM at 25C (77 F). Turnover temperature range is 20 to 30C (68 F to 86 F) and storage temperature is -55 to 125C (-67 to 257F). It has a maximum equivalent series resistance of 50 k and insulation resistance of 500 M at 100 VDC. It has a gold-over-nickel finish, and aging is ±3 PPM per year. It is RoHS-compliant. The crystal comes standard in a 3,000-unit taps and reel.
On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
