ABM8G-16.000MHZ-B4Y-T is an ultra-miniature ceramic glass sealed surface-mount crystal oscillator designed for high-density applications requiring compact form factors. The device operates at a fundamental frequency of 16.000 MHz with a frequency tolerance of ±20 ppm at +25°C and frequency stability of ±30 ppm over the operating temperature range of -20°C to +70°C. It features a hermetically sealed glass package measuring 3.2 × 2.5 × 1.0 mm with low height suitable for thin equipment, an equivalent series resistance of 80 O, shunt capacitance of 50 pF, and a load capacitance of 10 pF. The crystal is RoHS/RoHS II compliant, IR reflow capable, and offers high reliability with tight tolerance and stability, making it ideal for modems, communication equipment, test equipment, and wireless applications where space constraints and thermal performance are critical.
