福克斯晶振电子公司，一家领先的全球频率控制解决方案供应商和一家IDT公司，现在提供两种流行的晶振线作为标准库存，温度范围从-40°C到+85°C，共有五个封装和14个不同的频率。铅原型制作、样品和数量订单的时间几乎已经过去了淘汰。

将这些工业级石英晶振作为库存继续出售提供先进频率控制产品的目标有利于设计师的时间框架。这一承诺源于福克斯革命性XpressO振荡器的开发，包括极低成本、可配置的振荡器不到两个就能交付周，而典型的交付时间长达8周。

北美销售和营销经理罗杰•伯恩斯指出，“当今的频率控制应用要求组件能够在恶劣环境中有效运行。商业等级不再是常态。通过提供这些延伸温度晶体作为原料，我们有助于简化设计为我们的客户循环。“树脂密封的FQ SMD晶振的全系列现在已经可在-40°C至-40°C的扩展温度范围内现货供应+ 85摄氏度这些超低轮廓、低成本的晶体提供30的标准公差ppm和50ppm的标准稳定性，有四种标准包装尺寸寸:10mm×4.5mm,7mm×5mm,5.0mm×3.2mm,3.2mm×2.5mm

扩展温度HC49SDLF SMD晶体也可作为库存。这种电阻焊接石英晶体振荡器提供30ppm的标准公差和在3.2 MHz频率范围内50ppm的标准稳定性.

FOX Crystal 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°C 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.
