Low-Cost SMT Crystals Provide Precision T/F Reference

Said to enable the construction of custom oscillators with high stability and accurate frequency, the Series XH quartz crystals provide a stability from 20 ppm to 50 ppm from 0ûC to 70ûC and frequencies from 3 MHz to 80 MHz. The crystals are characterized by equivalent series resistance between 60½ and 200½. They come in a low profile, 13.5 mm x 4.7 mm x 4.5 mm resistance-welded package and the oscillator pads are coated with nickel barrier.
