Description
The YXC HC-49SMD 4 MHz is a reliable, industry-standard quartz crystal unit designed to provide a stable, low-frequency clock reference for digital electronic circuits. Operating at 4 MHz, this crystal is commonly used in applications where slower, power-efficient clocking is required, such as in basic microcontrollers, industrial timing controllers, and legacy communication systems.
Encased in the classic, resistance-welded HC-49SMD metal package, this crystal offers excellent environmental sealing and vibration resistance. Designed for surface-mount technology (SMT), it is highly compatible with automated PCB assembly processes. With a load capacitance of 20 pF and a frequency tolerance of ±20 ppm, it provides the accuracy and long-term stability needed for general-purpose timing applications. This package includes two units, making it an economical choice for dual-clock requirements or small-batch manufacturing.
