Product Description (Detailed):

Ensure precise timing and stable operation in your electronic projects with our high-quality 20 MHz Crystal Oscillator – HC-49S Quartz Crystal. This fundamental passive component is indispensable for microcontrollers, microprocessors, and any digital circuit requiring a highly accurate and stable clock source. The HC-49S package is a widely adopted industry standard for through-hole quartz crystals, known for its compact size, robust construction, and reliable performance.

At its core, a quartz crystal oscillator leverages the piezoelectric effect of a vibrating quartz crystal to generate a stable electrical signal at a very precise frequency. This 20 MHz crystal provides the exact 20 million cycles per second needed for many common microcontrollers (like certain AVR, PIC, and STM32 series) to execute instructions and perform time-sensitive operations with exceptional accuracy. Unlike LC or RC oscillators, crystal oscillators offer superior frequency stability across varying temperatures and over time, which is critical for reliable communication protocols, accurate data acquisition, and consistent system performance.

The HC-49S package makes for straightforward integration onto printed circuit boards (PCBs) and breadboards, allowing for easy prototyping and permanent installations. Typically, this crystal will be paired with two small ceramic capacitors (often 18pF to 22pF, depending on the microcontroller and crystal specifications) to form the complete oscillator circuit, optimizing its performance and ensuring it oscillates at its specified frequency. Whether you're building embedded systems, developing communication devices, creating digital clocks, or any project where precise timing is paramount, the 20 MHz Crystal Oscillator in the HC-49S package is an essential and reliable choice. Source your high-quality crystal in Pune or online to ensure the stable heart of your next electronic innovation.

The 20 MHz crystal oscillator is a high-precision, low-drift timing device used to generate a stable clock signal for digital circuits. With a frequency of 20,000,000 Hz, it’s especially useful in AVR-based systems and applications requiring fast clock cycles such as serial communication, frequency counters, and real-time processing.

The HC-49S package is breadboard and PCB friendly, making it perfect for DIY, academic, and industrial prototyping environments. The oscillator is typically used with two 22pF ceramic capacitors for load capacitance and stability in oscillation circuits.
