Description
The HC-49US 26 MHz Crystal is a high-precision, industrial-grade quartz resonator designed to provide a stable and accurate frequency reference for a wide range of electronic circuits. Operating at a fundamental frequency of 26 MHz, this crystal is an essential component for microcontrollers, communication systems, and frequency synthesizers where timing synchronization is critical for optimal performance.
Housed in the industry-standard HC-49US through-hole package, this crystal is engineered for high reliability and ease of integration into both prototyping breadboards and finished PCB assemblies. Its design features a resistance-welded, hermetically sealed structure that ensures excellent frequency stability and long-term durability. With a precise frequency tolerance of 20 PPM and a standard load capacitance of 20 pF, it delivers the consistent clock signals required for high-end digital applications.
