Description
The YXC HC-49SMD 7.3728 MHz is a high-performance, surface-mount quartz crystal unit designed to provide accurate and stable frequency control. Operating at 7.3728 MHz, this crystal is highly favored in embedded systems because this specific frequency can be easily divided to produce standard, accurate baud rates for serial communication (UART), minimizing data transmission errors.
Housed in a robust HC-49SMD 2-pad package, this crystal offers excellent mechanical stability and is optimized for automated surface-mount assembly processes. With a load capacitance of 12 pF and a tight frequency tolerance of ±20 ppm, it ensures consistent clock reliability for microcontrollers, communication hardware, and industrial instrumentation.
