HC-49US 3.6864 MHz Crystal Oscillator | 20pF | 20PPM | DIP Through-Hole

Description

The HC-49US 3.6864 MHz Crystal is a high-precision quartz resonator, specifically chosen for its unique frequency, which is a standard for baud rate generation in serial communication systems. Operating at exactly 3.6864 MHz, this crystal allows for precise division to achieve standard UART baud rates (such as 9600, 19200, or 38400) without significant error, making it an indispensable component for microcontroller-based serial interfaces.

Packaged in the industry-standard HC-49US 2-pin through-hole format, this crystal offers exceptional durability and easy integration into both breadboard prototypes and professional PCB designs. Its resistance-welded, hermetically sealed enclosure provides excellent protection against environmental contaminants. With a tight frequency tolerance of 20 PPM and a standard load capacitance of 20 pF, it ensures the stable, jitter-free timing performance necessary for reliable data transmission and digital signal processing.

Key Features
