Its compact 4-SMD package makes it ideal for space-constrained applications, ensuring reliable performance across a broad operating temperature range. This crystal belongs to the category of Crystals, Oscillators, and Resonators, specifically SMD MHz Crystals, and is a cornerstone component for modern electronic designs requiring precise frequency control.

Key Specifications

The SX1B38.400F1210F30 crystal boasts several critical specifications that define its performance and suitability for various applications. The Frequency of 38.4MHz indicates the primary oscillation rate, crucial for synchronizing digital circuits. An ESR (Equivalent Series Resistance) of 60Ω is a measure of the crystal’s internal resistance, directly impacting its quality factor and startup time; a lower ESR generally indicates a more efficient and stable oscillator. The Series designation of 1X often refers to a specific product line or internal design characteristic from the manufacturer. Its compact Size of 2.0×1.6×0.45mm highlights its small footprint, making it suitable for miniaturized electronic devices. The Mounting Type is Surface Mount, which is the industry standard for automated assembly processes, enabling high-density PCB designs. As a Component Type, it is clearly defined as a Crystal, distinguishing it from oscillators (which include internal circuitry) or resonators (which are often ceramic-based). The Package / Case is a 4-SMD (Surface Mount Device), indicating the number of pins and the surface-mount form factor. The specified Frequency Range of 16-54MHz suggests that this crystal is part of a series capable of covering a broad spectrum of frequencies, providing context for its specific 38.4MHz value. A Load Capacitance of 12pF is the external capacitance required to achieve the specified frequency accuracy, critical for proper oscillator circuit design. The Frequency Stability of ±30ppm (parts per million) quantifies how much the frequency can drift over its operating temperature range and aging, while the Frequency Tolerance of ±10ppm specifies the initial deviation from the nominal frequency at room temperature. Finally, the wide Operating Temperature range of -40℃ to +85℃ ensures robust performance in demanding industrial and automotive environments.
