Crystal Resonter
Utilizing the piezoelectric effect of quartz, Crystal Resonators offer excellent frequency stability and precision over a wide temperature range. JK provides a vast selection in both traditional through-hole (DIP, like HC-49 series) and space-saving surface-mount (SMD, sizes from 7050 down to 1612) packages. Available in fundamental frequencies from kilohertz (e.g., 32.768KHz watch crystals) for real-time clocks to hundreds of megahertz for microprocessors, communication systems, IoT devices, and general timing applications.
