DESCRIPTION
STATEK’s ultra-miniature, low profile CX7SM AT-cut crystals in leadless ceramic packages are designed for surface mounting on printed circuit boards or hybrid circuits. These crystals are low profile and have a very small land pattern. Maximum process temperature should not exceed 260OC.
FEATURES
Designed for surface mount applications using infrared, vapor phase, wave solder or epoxy mount techniques Low profile (less than 1.2mm) hermeitcally sealed ceraminc package Excellent aging characteristics Available with glass or ceramic lid High shock and vibration resistance Custom designs available Full military testing available Designed and manufactured in the USA
APPLICATIONS
Industrial, Computer & Communications General purpose clock oscillator PCMCIA Fax, Modem and LAN Smart card PDA and notebook computers Handheld instrumentation Cellular PCS Military & Aerospace Airborne hybrid computer Military high speed modem MCM CX7SM CRYSTAL
