The ABLS-5.000MHZ-B2-T is a 5.000 MHz SMD low-profile crystal oscillator housed in an HC/49US (AT49) package with dimensions of 11.5 × 4.7 × 4.2 mm. This fundamental-mode AT-cut crystal features a maximum equivalent series resistance (ESR) of 120 O, a shunt capacitance of 7 pF maximum, and a load capacitance of 18 pF. The device operates over a temperature range of -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. It is RoHS compliant, hermetically sealed with no moisture sensitivity (MSL N/A), and suitable for RoHS reflow processes. The crystal is ideal for applications in computers, modems, microprocessors, and wireless communication systems where stable frequency reference is required.
