從今以后，商業級的晶體不再會像之前一樣是常用產品了。現在工業級晶振已成為了使用的標準配置?，F成的擴展溫度可以消除開發。全球領先的頻率控制方案商FOX ELECTRONICS及IDT ELECTRONICS現在提供兩種流行晶體生產線作為標準庫存擴展溫度。溫度范圍在-40~+85度。共有五個封裝和14種不同頻率，免去了原型設計，樣品跟批量訂單的交貨時間。
　　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晶振把這些工業級晶體作為庫存來提供，在一個時間段內提供先進的頻率控制產品。這一場改革性的工業級晶體振蕩器開發都來源于?？怂咕д窆?。這是一種低成本可配置的振蕩器，在不到兩周的時間內可以完成。平常交貨期長達八周之久。
　　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晶振北美銷售和營銷經理指出：“今天的頻率元器件可以在惡劣環境中有效的運行，商業級的已經不再是常用系列?？梢酝ㄟ^提供這些擴展溫度晶體作為原料，有助于為客戶提供設計周期。”全系列樹脂密封FQ SMD晶體現已在-40至85度，擴展溫度已達85度。這些超薄型低成本晶體的標準公差為+-30PPM，標準穩定性為+-50PPM.有四種標準封裝尺寸可供選擇。

　　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.
