Crystals & Filters

Quartz crystal resonators (HC-49U, HC-49S, SMD 3225, 5032, 7050), crystal oscillators (TCXO, OCXO), ceramic resonators, and SAW filters for TV and radio IF stages. Standard frequencies: 4, 8, 12, 16, 20, 24, 25, 27 MHz and 32.768 kHz watch crystals. Filter by frequency, tolerance (ppm), load capacitance CL, and package. Used as clock sources for MCUs, USB controllers, and RTC modules, as IF filters in radios and TVs, and in Ethernet and Wi-Fi front-ends.
