Quartz Crystals

Apart from our finished quartz frequency control products, quartzMorion  manufactures a wide range of crystals of various designs for frequencies ranging from 4 kHz to 200 MHz. For these crystals we employ quartz elements manufactured along the most commonly used cuts. Morion offers the crystals in standard HC-52, HC-49 and HC-33 packages.
