The 49ASC40233202030 is a DIP Crystal Resonator with HC-49S case manufactured by JGHC. It is RoHS compliant and provides accurate frequency control between 20.3 to 30 MHz. The resonator is ideal for applications requiring improved frequency stability such as power-sensitive devices. The resonator consists of a parallel-resonant, quartz crystal unit encased in a hermetically-sealed, ceramic package. Its high-quality construction ensures stable frequency characteristics, enabling the lower power and the higher accuracy, which makes it an ideal choice for digital and analog applications. The resonator is easy to install and maintain, and its low EMI/RFI emissions make it a great choice for a wide range of applications.
