Description
The YSX321SL 16 MHz is a high-precision, 4-pin surface-mount quartz crystal housed in a durable metal package. Operating at a nominal frequency of 16 MHz, this component is a reliable clock reference for various digital electronics, including microcontrollers, communication interfaces, and embedded systems requiring stable, low-jitter timing.
Featuring a 4-pin SMD configuration and a rugged metal surface finish, the YSX321SL provides superior electromagnetic shielding, which is critical for minimizing noise coupling in sensitive or high-density PCB designs. With a load capacitance of 18 pF and a tight frequency tolerance of ±10 ppm, this crystal ensures a clean and accurate clock signal. This pack includes two units, providing a convenient solution for multi-channel hardware designs or prototyping.
