Key Specifications

The SX0B27.120F0810F30 crystal boasts several critical specifications that define its performance and suitability for specific applications. The Frequency of 27.12MHz indicates the nominal oscillation frequency the crystal is designed to produce, a common frequency for various radio frequency (RF) and data communication protocols. The Frequency Tolerance of ±10ppm (parts per million) specifies the maximum allowable deviation from the nominal frequency at room temperature, highlighting its precision. A lower ppm value signifies higher accuracy. The Frequency Stability of ±30ppm over the operating temperature range indicates how much the frequency can drift due to temperature changes, which is vital for maintaining timing accuracy in environments with fluctuating temperatures. The ESR (Equivalent Series Resistance) of 200Ω is a critical parameter that affects the crystal’s ability to start oscillating and its power consumption; a lower ESR generally indicates a more efficient and easier-to-drive crystal. The Load Capacitance of 8pF is the external capacitance required by the crystal to oscillate at its specified series or parallel resonant frequency, essential for proper circuit design. The Size (mm) of 1.6×1.2×0.35 illustrates its ultra-compact form factor, making it suitable for miniaturized electronic devices. The Operating Temperature range of -40℃ to +85℃ demonstrates its robust performance across extreme industrial and automotive temperature conditions. The Mounting Type is Surface Mount (SMD), indicating it is designed for automated assembly processes, and its Package / Case is a 4-SMD, specifying the physical form factor for PCB integration. The Frequency Range of 24-54MHz indicates the broader family of frequencies available in this series, offering context for this specific 27.12MHz part.
