Description
The HC-49SMD 8.192 MHz is a precision quartz crystal resonator highly valued for its role in timing and digital clocking applications. The 8.192 MHz frequency is a power-of-two multiple, making it extremely efficient for use in digital systems requiring precise clock division for protocols such as UART, SPI, or for creating stable timing bases in embedded controllers.
Housed in the industry-standard HC-49SMD low-profile metal package, this crystal is designed to withstand mechanical vibrations while providing excellent frequency stability. With a load capacitance of 20 pF and a tight frequency tolerance of ±20 ppm, it minimizes jitter and ensures accurate timing in sensitive communication circuits. This pack includes two units, making it an ideal choice for prototyping or for applications requiring a consistent timing reference across multiple channels.
