Product Overview
The AT3*8 series crystal oscillators from Zhongshan Huiyuan Crystal Electronic Technology Co., Ltd. offer a range of normal frequencies from 4 to 27MHz and 32.768000KHz. Designed for fundamental oscillation mode, these components support various load capacitances including 12PF, 12.5PF, and 20PF. They provide precise frequency stability over a wide operating temperature range of -30 to +80, with specific tolerances of 10 PPM or 20 PPM at 253 and 30 PPM across the operating temperature. Key features include low effective series resistance, a typical drive level of 1.0 uW, and high insulation resistance (500 M at DC 100V). These crystals are suitable for applications requiring reliable frequency control.
