Crystal 8.000MHz 49S 20PPM 20pF 40Ω

Crystal 8.000MHz 49S 20PPM 20pF 40Ω

This component is an 8.000MHz quartz crystal resonator, a fundamental frequency control device in electronic circuits. Housed in the standardized HC-49/S package, it is a through-hole component designed for soldering directly onto printed circuit boards (PCBs). Its primary role is to generate a highly stable and precise clock frequency, which serves as the timing heartbeat for digital systems, ensuring synchronized and accurate operation.

The crystal’s performance is defined by its exceptional accuracy, with a frequency tolerance of ±20 parts per million (PPM) at room temperature. This means the actual frequency will deviate by no more than a minuscule amount from the specified 8.000MHz. To operate at this exact frequency, it requires an external load capacitance of 20 picofarads (pF) in the oscillator circuit. Furthermore, it exhibits a low Equivalent Series Resistance (ESR) of 40 ohms, indicating high efficiency and quality in its oscillation.

The resonator is built around a carefully crafted “AT-cut” quartz wafer, known for its excellent frequency stability over a wide temperature range. This wafer is hermetically sealed inside a metal HC-49/S package, which protects the sensitive crystal from environmental contaminants, moisture, and physical shock. This robust construction ensures reliable long-term performance and contributes to minimal aging, allowing the crystal to maintain its specified accuracy for years.
