Product Overview
The HC49S-2DIP series crystal oscillators from Zhongshan Huiyuan Crystal Electronic Technology Co., Ltd. are fundamental mode oscillators designed for a frequency range of 3.579545 to 39.550MHz. These components offer a load capacitance of 6-44PF and a frequency tolerance of 20PPM at 253. They are suitable for applications requiring stable operation across a wide temperature range of -40 to +85, with a stability of 30 PPM over the operating temperature range. Key specifications include an effective series resistance varying by frequency range, shunt capacitance of 5 PF, and a typical drive level of 100 uW TYP. The insulation resistance is 500 M at DC 100V, and the aging rate is 3 PPM/Year. These crystal oscillators are tested using the S&A 250B Pi-Network Crystal Measurement System.
