River Eletec Corporation produce the world’s smallest smd precision quartz crystals with sizes from (1.2 x 1.0)mm and 0.33mm in height. Packaged in ceramic and metal vacuum sealed packages for ultimate reliability with a high resistance to mechanical shock and vibration due to their low mass. Frequencies range from the ubiquitous 32.768kHz to 80MHz for fundamental designs. Continuous research and product development maintains the leadership in quality and minimal size together with exceptional customer support.
Precision quartz crystals, high stability HI-REL quartz crystals, SC cut, BT cut, IT cut and AT cut crystals, miniature precision crystals, HC-43/U, HC-26/U, low profile miniature smd crystals, low phase noise SC cut quartz crystals, low ageing crystals, low phase noise. Glass, resist weld and cold weld cases, vacuum sealed.
