Description
The YSX321SL 20 MHz is a high-precision, 4-pin surface-mount quartz crystal housed in a durable metal package. Operating at a nominal frequency of 20 MHz, this component serves as a reliable master clock reference for a broad range of digital applications, including microcontrollers, high-speed serial communication interfaces, and industrial automation controllers.
Featuring a 4-pin SMD configuration and a rugged metal surface finish, the YSX321SL is engineered to provide superior electromagnetic shielding, which is critical for maintaining signal integrity in high-density board designs. With a load capacitance of 20 pF and a tight frequency tolerance of ±10 ppm, this crystal ensures a clean, stable, and low-jitter clock signal. This pack includes two units, making it a convenient and cost-effective choice for multi-board projects or hardware prototyping.
