Due to its robust design this crystal has gained wide acceptance in the industry. FEATURES Low profile, hermetically sealed ceramic package Excellent ageing characteristics High shock resistance Full military testing available Available with glass or ceramic lid Custom designs available CX-1-03 AT CRYSTAL Miniature AT-Cut Quartz Crystal 8MHz to 160MHz OUTLINE & DIMENSIONS SPECIFICATION Fundamental Frequency: 10.0MHz 32.0MHz 155.52MHz Motional Resistance R (Ω): 50 20 50 Motional Capacitance C1 (fF): 5.5 7.8 0.5 QualityFactor Q (k): 80 306 41 Shunt Capacitance C0 (pF): 2.2 2.6 3.2 Calibration Tolerance1: A = ±0.01% (±100ppm) B = ±0.1% C = ±1% Load Capacitance: 20pF (Unless specified by customer) Drive Level: 500µW maximum Temperature Stability2 Commercial -10 ~ +60°C: from ±10ppm Industrial -40 to +85°C: from ±20ppm Military -55 to +125°C: from ±30ppm Ageing, first year: 5ppm maximum Shock, survival3: 3,000g, 0.3ms, ½ sine Vibration, survival: 20g, 10~2000Hz swept sine Operating Temperature Range Commercial: -10° to +70°C Industrial: -40° to +85°C Military: -55 to +125°C Storage Temperature Range: -55° to +125°C Maximum Process Temperature: See package handling notes Specifications stated are typical at 25°C unless otherwise indicated. Specifications may change without notice. Note: The characteristics of the frequency temperature stability follow that of AT-Cut Thickness Shear mode. 1. Tighter tolerances available. 2. Does not include calibration tolerance. 3. Higher shock version HOW TO ORDER CX-1-03 CRYSTALS CX-1 - S - OT - C -03 - 32M, A / 25 / I 'S' if special, custom design. Otherwise leave blank Blank = glass lid C = ceramic lid Side Leads Frequency K = kHz M = MHz Calibration Tolerance @25°C A B C Temp. Range C = -10° ~ +70°C I = -40° ~ +85°C M = -55° ~ +125°C S = Customer specified OT = 3rd Overtone Mode. Blank = Fundamental Mode Frequency Stability over temp. (in ppm) PACKAGE HANDLING The CX crystal is hermetically sealed in a ceramic package. Normal handling and soldering precautions for small, low thermal mass parts are adequate when installing or testing CX crystals. CX crystals may be wave soldered with proper precaution taken to avoid desoldering the leads. A slow machine rate or too high a pre-heat temperature or solder bath temperature may damage the crystals. Lead to package solder interface temperature should not exceed 175°C, glass lid to package seal rim temperature should not exceed 210°C. If the seal rim reaches temperatures above the maximum specified, the package may lose its hermeticity. Loss of hermeticity results in a frequency decrease and motional resistance increase. STANDARD FREQUENCIES 10.0, 11.0592, 12.0, 16.0, 19.66080, 20.0, 24.0, 24.576, 30.0, 32.0, 35.2512, 36.0 and 40.0MHz |
