从今以后，商业级的晶体不再会像之前一样是常用产品了。现在工业级晶振已成为了使用的标准配置。现成的扩展温度可以消除开发。全球领先的频率控制方案商FOX ELECTRONICS及IDT ELECTRONICS现在提供两种流行晶体生产线作为标准库存扩展温度。温度范围在-40~+85度。共有五个封装和14种不同频率，免去了原型设计，样品跟批量订单的交货时间。
　　From now on, commercial grade crystals will no longer be common products as before. Industrial crystal oscillators are now standard equipment. Off-the-shelf extended temperatures can eliminate development. FOX ELECTRONICS and IDT ELECTRONICS, the world's leading frequency control solutions providers, now offer two popular crystal production lines as standard stock expansion temperatures. The temperature range is -40 to +85 degrees. A total of five packages and 14 different frequencies eliminates the need for prototyping, sample and lead time delivery.

　　FOX晶振把这些工业级晶体作为库存来提供，在一个时间段内提供先进的频率控制产品。这一场改革性的工业级晶体振荡器开发都来源于福克斯晶振公司。这是一种低成本可配置的振荡器，在不到两周的时间内可以完成。平常交货期长达八周之久。
　　The FOX crystal provides these industrial grade crystals as an inventory to provide advanced frequency control products over a period of time. This revolutionary industrial grade crystal oscillator was developed from Fox Crystal. This is a low cost configurable oscillator that can be completed in less than two weeks. The usual delivery time is as long as eight weeks.
　　FOX晶振北美销售和营销经理指出：“今天的频率元器件可以在恶劣环境中有效的运行，商业级的已经不再是常用系列。可以通过提供这些扩展温度晶体作为原料，有助于为客户提供设计周期。”全系列树脂密封FQ SMD晶体现已在-40至85度，扩展温度已达85度。这些超薄型低成本晶体的标准公差为+-30PPM，标准稳定性为+-50PPM.有四种标准封装尺寸可供选择。

　　FOX Crystal North America sales and marketing manager pointed out: "Today's frequency components can operate effectively in harsh environments, commercial grades are no longer a common series. Can provide customers with these extended temperature crystals as raw materials. Design cycle.” The full range of resin-sealed FQ SMD crystals are now available at -40 to 85 degrees and have an extended temperature of 85 degrees. These ultra-thin, low-cost crystals have a standard tolerance of +-30PPM and a standard stability of +-50PPM. Available in four standard package sizes.
