Description
The HC49/U 4 MHz Crystal is a robust and highly stable quartz resonator engineered for reliable frequency generation. Operating at a fundamental frequency of 4 MHz, this component is widely used as a primary clock source in microcontrollers, digital timing circuits, and embedded systems where a lower, power-efficient clock speed is desired for application logic.
Housed in the industry-standard HC49/U through-hole package, this crystal offers excellent physical durability and electrical performance. Its hermetically sealed design ensures the quartz element remains protected from humidity, dust, and oxidation, guaranteeing long-term operational consistency. It is a preferred choice for developers working on general-purpose electronics, communication modules, and automated control systems.
