Fox Electronics, a leading global supplier of frequency control solutions and an IDT company, now offers two popular crystal lines as standard stock in the extended temperature range of -40 to +85°C, with a total of five packages and 14 different frequencies. Lead times for prototyping, samples and quantity orders have been virtually eliminated.

Making these industrial grade crystals available as stock continues Fox’s goal of providing advanced frequency control products within timeframes that benefit designers. This commitment stems from the development of Fox’s revolutionary XpressO oscillators, which are extremely low cost, configurable oscillators delivered in less than two weeks versus typical delivery times of up to eight weeks.

Roger Burns, North American sales and marketing manager, noted, “Today’s frequency control applications mandate components that can operate effectively in harsh environments.  Commercial grade just isn’t the norm anymore. By offering these extended temperature crystals as stock, we help facilitate the design cycle for our customers.”

The full line of resin-sealed FQ SMD crystals is now available off-the-shelf in the extended temperature range of -40°C to +85°C. These ultra-low profile, low cost crystals offer standard tolerances of ±30 ppm and standard stabilities of ±50 ppm and are available in four standard package sizes:

  • 10 x 4.5 mm
  •      7 x 5 mm
  •   5 x 3.2 mm
  • 3.2 x 2.5 mm

The extended temperature HC49SDLF SMD crystal is also available as stock.  This resistance weld crystal offers standard tolerances of ±30 ppm and standard stabilities of ±50 ppm across a frequency range of 3.2 to 80 MHz in a standard HC49S-SMD 13.9 x 5 mm package.
