Fox Electronics: SMD Crystal material Change To establish multiple production facilities as a safeguard against supply chain interruption, and to allow us to offer the best possible lead times and pricing, we are expanding our production process for the above products to include resin sealed ceramic packaging as well as the current all quartz packaging. Any parts ordered in the future can be either quartz or ceramic package material. The model and part numbers will be the same for quartz and ceramic packages. Electrical and dimensional specifications are the same for both package materials and are unchanged from current FQ series specifications. Product can still be provided in all quartz packaging only for any customers who can accept only all quartz. Pricing and lead time flexibility may be affected however. Please contact your Mouser Technical Representative for additional information. 5-0310-35
