Microchip’s EX-219 is a Radiation Tolerant, Space Qualified, Evacuated Miniature Crystal Oscillator (EMXO). An EMXO is a unique miniaturized oven-controlled oscillator in an evacuated cavity. This design provides a small physical size, low profile, low-power consumption, fast warm-up and tight temperature stability. The EX-219 bridges the cost/size/performance gap that exists between small, lower power and large, higher power Space OCXO offerings. By delivering SC-cut OCXO performance in a greatly reduced footprint, Microchip's solution delivers a powerful combination of performance and miniaturization. Leveraging our Class S QPL manufacturing line, flight heritage, and leading OCXO technology, the EX-219 offers exceptional performance and reliability from LEO to Deep Space. Flight units utilize Swept Quartz, a 4-point Crystal Mount, Class K Element Evaluation IAW MIL-PRF-38534, and Class S Screening IAW MIL-PRF-55310. Engineering Models (EM) are fit, form, and functional equivalents of the Flight Models (FM) and can withstand the same environmental envelope less radiation.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
EX-219 is an authentic electronic component manufactured by Microchip, categorized under Frequency Control & Timing Devices. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official EX-219 datasheet above.
Electronic component spot-market pricing for EX-219 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for EX-219 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
