CX2SM AT CRYSTAL 9.6 MHz to 250 MHz Low Profile, Miniature Surface Mount AT Quartz Crystal actual size DESCRIPTION STATEK’s miniature CX2SM AT crystals in leadless ceramic packages are designed for surface mounting on printed circuit boards or hybrid substrates. These crystals are low profile and have a small footprint. The CX2SM crystal is manufactured using the STATEK-developed photolithographic process, and was designed utilizing the experience acquired by producing millions of crystals for industrial, commercial, military and medical applications.
