32.768 KHz fundamental crystal oscillator Huiyuan crystal HY32768KSMD3068YA2R30 with 30 PPM temperature stability
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.
