Key Specifications

The SX1B38.400F1010F30 boasts several critical specifications that define its performance and suitability for various applications. The Frequency of 38.4MHz indicates the precise oscillation rate it generates, a common frequency for many digital and wireless applications. An ESR (Equivalent Series Resistance) of 60Ω is a measure of the crystal’s internal resistance, where a lower ESR generally indicates a higher quality crystal with better startup characteristics and lower power consumption. The Series designation of 1X refers to a fundamental mode crystal, meaning it oscillates at its base frequency rather than a harmonic. Its compact Size of 2.0×1.6×0.45mm highlights its suitability for miniaturized designs, enabling high-density PCB layouts. The Mounting Type is Surface Mount, which is the industry standard for automated assembly and compact designs. Classified as a Component Type Crystal, it is a passive device that generates a precise frequency when excited. The Package / Case is 4-SMD, denoting its small outline surface mount package with four terminals. The broad Frequency Range of 16-54MHz indicates that this specific crystal falls within a versatile family of components. A Load Capacitance of 10pF is the external capacitance required to achieve the specified frequency, crucial for proper circuit design and frequency accuracy. The Frequency Stability of ±30ppm (parts per million) over the operating temperature range indicates how much the frequency can drift due to temperature changes, a critical parameter for applications requiring consistent timing. Finally, the Frequency Tolerance of ±10ppm at 25℃ specifies the initial accuracy of the crystal at room temperature, ensuring precise operation from the outset. The wide Operating Temperature range of -40℃ to +85℃ ensures robust performance in challenging environmental conditions, making it suitable for industrial and automotive applications.
