Its small footprint and robust design make it suitable for modern, miniaturized electronic devices where space is at a premium.

Key Specifications

The SX1B39.000F1010F30 crystal boasts several key specifications that define its performance and suitability for demanding applications. Its Frequency of 39MHz indicates the precise oscillation rate it generates, a critical parameter for timing and clocking functions in microcontrollers, RF transceivers, and digital signal processors. The ESR (Equivalent Series Resistance) of 60Ω is a measure of the crystal’s internal resistance, influencing its Q-factor and start-up characteristics; a lower ESR generally indicates a more efficient and stable oscillation. The Series designation as 1X refers to a specific product line or series from SCTF, often indicating a particular performance tier or package style. With a compact Size (mm) of 2.0×1.6×0.45, this crystal is designed for space-constrained applications, facilitating miniaturization of electronic products. Its Mounting Type is Surface Mount, meaning it is designed to be soldered directly onto the surface of a PCB, enabling automated assembly and high-density layouts. The Component Type is clearly identified as a Crystal, distinguishing it from oscillators (which include an internal active circuit) or resonators (which are typically ceramic and less precise). The Package / Case is a 4-SMD (Surface Mount Device), indicating the physical form factor and pin configuration for soldering. It operates within a broad Frequency Range of 16-54MHz, suggesting the design flexibility of this crystal series. A Load Capacitance of 10pF is the external capacitance required to achieve the specified frequency, crucial for proper circuit design and frequency tuning. The Frequency Stability of ±30ppm over the operating temperature range indicates how much the frequency can drift due to temperature variations, while the Frequency Tolerance of ±10ppm specifies the initial deviation from the nominal frequency at room temperature. Finally, an Operating Temperature range of -40℃ to +85℃ ensures reliable performance in a wide array of industrial and commercial environments.
