Quartz Crystals

Quartz crystals are used in a wide range of electronic applications. The High Q factor of the quartz means that tight stabilities can be achieved; this is key to ensuring microprocessor timing circuits work correctly within customer’s designs. IQD offers an extensive range of Quartz Crystals covering both surface mount and legacy leaded devices that satisfy most applications; many devices are suitable for custom designs. Our range includes:

 Standard Crystals
