Description
The YSX321SL is a high-performance 4-pad surface-mount (SMD) quartz crystal resonator, engineered to provide an exceptionally stable clock signal for demanding digital electronic systems. Operating at a fundamental frequency of 27 MHz, this crystal is an ideal choice for high-speed microcontrollers, networking equipment, and wireless communication modules where timing synchronization and frequency stability are critical for reliable data transmission.
This crystal features a durable metal surface construction that provides excellent electromagnetic interference (EMI) resistance and mechanical robustness. Designed for modern high-density PCBs, its compact 4-pad SMD footprint is optimized for automated assembly processes (reflow soldering), ensuring high manufacturing efficiency and consistent performance. With a tight frequency tolerance of 10 PPM, it offers significantly reduced frequency drift compared to standard resonators, ensuring your system operates with maximum precision.
