HC-49US 4.9152 MHz Crystal Oscillator | 20pF | 20PPM | DIP Through-Hole

Description

The HC-49US 4.9152 MHz Crystal is a high-precision quartz resonator, widely utilized in communication hardware and embedded systems. This specific frequency is a preferred choice in digital design because 4.9152 MHz is a highly “divisible” frequency, allowing for the generation of standard serial communication baud rates (such as 9600, 19200, or 38400) with extremely low error margins when used with common microcontrollers and UART modules.

Housed in the robust, industry-standard HC-49US 2-pin through-hole package, this crystal is designed for reliability and ease of integration into both prototyping boards and production PCB assemblies. The resistance-welded, hermetically sealed enclosure provides excellent protection against environmental contaminants like humidity and oxidation. With a frequency tolerance of 20 PPM and a standard load capacitance of 20 pF, it delivers the consistent, stable, and low-jitter clock signal essential for high-performance digital projects.

Key Features

• Optimal for UART/Serial: The 4.9152 MHz frequency is mathematically ideal for generating standard baud rates with negligible error.
• High Accuracy: A tight 20 PPM tolerance ensures your system clock remains stable and synchronized.
