YSX321SL 18.432 MHz 20pF ±10ppm 4-Pin SMD Metal Surface Quartz Crystal (Pack of 2)

Description

The YSX321SL 18.432 MHz is a high-precision, 4-pin surface-mount quartz crystal engineered to provide a stable clock reference for digital systems. This specific frequency, 18.432 MHz, is highly valued in embedded systems design because it is a “baud-rate friendly” frequency. It can be easily divided by internal microcontroller hardware to produce standard, error-free baud rates (such as 9600, 19200, 38400, or 115200 bps) for UART serial communication, ensuring reliable data transmission.

Encased in a robust metal-surface SMD package, the YSX321SL is designed for high-density PCB layouts and automated surface-mount assembly. With a load capacitance of 20 pF and a tight frequency tolerance of ±10 ppm, this crystal provides consistent, accurate timing for microcontrollers, communication interfaces, and industrial hardware. This package includes two units, making it an excellent choice for dual-clock projects or prototyping.
