The Epson Q22FA12800594 SMD Crystal Resonator SMD-2016_4P RoHS is an electronic component used for frequency control in electronic circuits. It consists of an AT-cut quartz crystal mounted in a rectangular, surface-mountable package, and is designed to operate from 14.5-26 MHz in the prescence of a temperature range of -20 to +75 degrees Celsius. It provides excellent frequency stability across the given temperature range, and is sourced on Rohs compliant sheet materials. It is suitable for a wide range of applications, including, but not limited to, quartz crystal oscillator circuits, timing control circuits, and oscillation control circuits.
