描述
ECS-147.4-S-1 is an HC-49U quartz crystal designed for precision timing applications, featuring AT-cut crystal technology with excellent aging characteristics and tight frequency tolerances. The device operates across a frequency range of 1.8 MHz to 100 MHz in fundamental mode, with frequency tolerance of ±30 ppm at +25°C and frequency stability of ±50 ppm over the operating temperature range of -10°C to +70°C. Key electrical parameters include maximum equivalent series resistance (ESR) varying by frequency band (750 O at 1.8–1.999 MHz down to 20 O at 16–25 MHz), shunt capacitance of 7.0 pF maximum, and load capacitance of 10.0 pF (series resonance). The crystal exhibits excellent first-year aging of ±5.0 ppm at +25°C and is housed in the compact HC-49U package with dimensions of 11.35 mm × 4.88 mm. This cost-effective component is ideal for consumer electronics, telecommunications, and industrial timing applications requiring reliable frequency reference with minimal aging drift.
