Product Overview
The SMD3068 series crystal oscillator from Zhongshan Huiyuan Crystal Electronic Technology Co., Ltd. is designed for applications requiring stable frequency reference. It operates on a fundamental oscillation mode with a nominal frequency of 32.768000KHz and a load capacitance of 12.5 PF. This component offers a frequency tolerance of 20PPM at 253 and 30 PPM across its operating temperature range of -40 to +85. Key specifications include an effective series resistance of 70 K, shunt capacitance of 3 PF, and a typical drive level of 10uW. It is suitable for environments with storage temperatures from -55 to +125, featuring an insulation resistance of 500 M at DC 100V and an aging rate of 3 PPM/Year. The crystal oscillator is tested using the S&A 250B Pi-Network Crystal Measurement System.
