The AB308-12.000MHZ is a high-frequency cylindrical microprocessor crystal designed for precision timing applications. This miniature crystal features a 12.000 MHz fundamental frequency with tight vacuum sealing to ensure high stability and reliability across operating conditions. The device operates over a temperature range of -10°C to +60°C with frequency stability of ±50 ppm over the operating temperature range (referenced to +25°C), and maintains a frequency tolerance of ±30 ppm at +25°C. With an equivalent series resistance of 30 O, shunt capacitance of 5 pF maximum, and a typical load capacitance of 16 pF, this crystal is well-suited for clocks in microprocessor systems, consumer electronics, test equipment, and computer peripherals. The compact 8.0 × 3.0 mm cylindrical package and low drive level of 100 µW maximum make it an ideal choice for space-constrained applications requiring stable frequency references.
