CX18 AT CRYSTAL 30 MHz to 50 MHz Ultra-Low Profile Ultra Low Weight Surface Mount Quartz Crystal DESCRIPTION When miniaturization is paramount, Statek’s extremely small CX18 quartz crystal is the most ideal choice. This crystal is available in frequencies from 30 MHz to 50 MHz, and has typical overall dimensions of 1.55 mm x 0.95 mm x 0.35 mm. This surface mount crystal is hermetically sealed within an ultra-miniature ceramic package to ensure high stability and low aging. The extremely small size of this crystal makes the CX18 ideally suited for many high frequency applications. glass lid PACKAGE DIMENSIONS FEATURES Ultra-Miniature Package Ultra-Low profile Ultra-low weight (1.8 mg) Hermetically sealed package TYPICAL DIM inches mm A 0.061 1.55 Full military testing available B 0.037 0.95 Designed and manufactured in the USA C Excellent aging characteristics APPLICATIONS see below D 0.020 Medical Cardiac rhythm management Pacemakers Defibrillators THICKNESS (DIM C) Lid Glass or Ceramic Medical Telemetry 0.51 Termination Typical inches mm SM1 0.0138 0.35 Neurostimulators Military & Aerospace Missle Telemetry Ruggedized Communications Aircraft Electronics Smart Munitions Industrial & Communications Bio-Tracking Process Control Portable Instrumentation 10207 Rev A STATEK CORPORATION 512 N.
