20.000MHz Low Profile Crystal

This 20.000MHz low-profile crystal oscillator is a precision frequency reference for microprocessor and digital timing applications. The crystal operates in the fundamental mode, providing a stable clock source with a low equivalent series resistance (ESR) to ensure reliable oscillation in a wide range of microcontroller, FPGA, and communication ICs.

Enclosed in a low-profile, hermetically sealed package, this crystal is designed to minimize board height while delivering the frequency accuracy required for serial communications, real-time clocks, and system clocks. The standard HC-49 package footprint supports conventional through-hole or surface-mount conversion, making it suitable for both legacy and new designs.
