ABLS-8.000MHZ-B4-T is an SMD low-profile crystal oscillator operating at 8.000 MHz in fundamental mode, housed in a compact HC/49US (AT49) package measuring 11.5 × 4.7 × 4.2 mm. The device features an equivalent series resistance (ESR) of 80 O maximum, a shunt capacitance of 7 pF maximum, and a load capacitance of 18 pF standard, with drive level capability up to 1 mW maximum (100 µW typical). Operating temperature range is -20°C to +70°C with frequency tolerance of ±50 ppm at +25°C and frequency stability of ±50 ppm over the operating temperature range. The crystal is RoHS compliant, hermetically sealed with no moisture sensitivity (MSL N/A), and suitable for RoHS reflow processes, making it ideal for computers, modems, microprocessors, and wireless applications requiring stable timing references.
