20 MHz HC-49S Low-Profile Quartz Crystal (Arduino, Raspberry Pi)

This 20 MHz HC-49S crystal is a high-reliability quartz resonator designed to provide a precise frequency reference for microcontrollers and logic circuits. Housed in a low-profile HC-49/S metal package, it supports fundamental frequencies ranging from 3.2 MHz to 36 MHz. Ideal for Arduino, Raspberry Pi, and other embedded projects, this component ensures thermal stability and tight tolerance for accurate clock signal generation.
