Product Overview
The 49SB-SMD series crystal oscillators from Zhongshan Huiyuan Crystal Electronic Technology Co., Ltd. are designed for fundamental oscillation mode with a normal frequency range of 6.7458 to 32MHz. They offer precise frequency tolerance of 10 PPM at 253 and 20 PPM over a wide operating temperature range of -20 to +70. These SMD components feature a low shunt capacitance (5 PF) and are suitable for applications requiring stable frequency control within a -40 to +85 operating temperature range.
