Product Overview
The 49SB-SMD series crystal oscillators from Zhongshan Huiyuan Crystal Electronic Technology Co., Ltd. are designed for fundamental oscillation mode, offering a normal frequency range from 6.7458MHz to 32MHz. These components are engineered for reliable performance with a load capacitance of 20PF and a frequency tolerance of 10 PPM at 253. They maintain stability over a wide operating temperature range of -40 to +85, with a frequency deviation of 20 PPM from -20 to +70. The series features a low effective series resistance, varying by frequency band, and a typical drive level of 10 uW. Suitable for applications requiring precise frequency control, these crystals are manufactured with high insulation resistance (500 M at DC 100V) and a low aging rate (3 PPM/Year).
