7.3728 MHz Quartz Crystal – HC‑49 Through‑Hole Package
The 7.3728 MHz quartz crystal provides a precise and stable frequency reference for timing and clock generation in embedded systems, communication devices, and industrial electronics. Its nominal 7.3728 MHz frequency and HC‑49 through‑hole package ensure reliable PCB integration, while the sealed quartz wafer in a hermetic enclosure maintains consistent performance over time.
This crystal is suitable for microcontroller clocks, UART communication, and precision oscillator applications. With a tight frequency tolerance and controlled load capacitance, it enables accurate UART baud rates such as 115200 bps and ensures stable timing intervals with minimal jitter. Operating reliably across temperatures from –40 °C to +85 °C, it supports industrial and commercial applications requiring stable frequency references.
The low equivalent series resistance (ESR) reduces energy loss and supports stable oscillator operation. The HC‑49 package protects the quartz from environmental factors and mechanical stress, ensuring long-term reliability. The 7.3728 MHz crystal is suitable for microcontroller timing, communication systems, and embedded electronics.
