830027298B – WURTH

The 830027298B is a 4.0 MHz WE-XTAL quartz crystal oscillator, manufactured by Wurth Elektronik. This surface-mount device (SMD) provides a stable frequency reference for timing applications. The crystal likely utilizes a fundamental mode AT-cut quartz crystal resonator, offering a specified frequency of 4.0 MHz. Key parameters would include a tight frequency tolerance and temperature coefficient, essential for precision timing circuits. The device’s equivalent series resistance (ESR) and shunt capacitance would be critical specifications for oscillator design. The crystal’s drive level and operating temperature range would also be important considerations during circuit design. The WE-XTAL series is designed for reliable performance in a variety of electronic systems, providing a stable clock signal for microcontrollers, communication modules, and other frequency-dependent circuits.
