Quartz-Based Microprocessor Crystals

Crescent Frequency Products offers a wide selection of microprocessor crystals in industry standard surface mount (SMD) and though hole packages with many sizes to choose from. We manufacture in both the KHz and MHz frequency ranges. Ordering information is located in each of the PDF datasheets below. If you would like assistance putting a part number together or you need a custom specified product to meet your specific design requirements please contact our sales department via our contact page.

Crystal: a thin, natural or synthetic, piezoelectric crystal of silicon dioxide cut and ground to a precise thickness so as to vibrate at a particular frequency when supplied with energy
