Key Specifications

The SX1B48.000F1010F30 boasts several critical specifications that define its performance and suitability for various applications. The Frequency of 48MHz indicates the nominal oscillation rate, making it ideal for systems requiring a fast and precise clock. The Frequency Tolerance of ±10ppm (parts per million) signifies the maximum allowable deviation from the nominal 48MHz at room temperature, ensuring a very high degree of initial accuracy crucial for sensitive timing applications. Complementing this, the Frequency Stability of ±30ppm over the entire operating temperature range (-40℃ to +85℃) guarantees consistent performance even under varying environmental conditions. The ESR (Equivalent Series Resistance) of 50Ω is a measure of the crystal’s internal resistance, indicating its efficiency and ease of driving; a lower ESR generally means easier integration into oscillator circuits. The Load Capacitance of 10pF is the external capacitance required by the oscillator circuit to achieve the specified frequency, a vital parameter for circuit designers to match for optimal performance. Its compact Size (mm) of 2.0×1.6×0.45 makes it suitable for miniaturized electronic devices where board space is at a premium. The Mounting Type is Surface Mount (SMD), facilitating automated assembly processes and enabling high-density PCB designs. The Package / Case is a 4-SMD, a standard footprint for modern crystal units. The Operating Temperature range of -40℃ to +85℃ highlights its robustness, allowing it to function reliably in demanding industrial and automotive environments. The Frequency Range of 16-54MHz for the 1X Series indicates that this particular crystal is part of a family designed for a broad spectrum of high-frequency applications.
