Key Specifications

The SX1B25.000F1210F30 crystal boasts several critical specifications that define its performance and suitability for various applications:

• ESR (Equivalent Series Resistance): 80Ω – ESR is a measure of the crystal’s internal resistance. A lower ESR generally indicates a higher quality crystal that requires less power to oscillate and can start up more reliably. An 80Ω ESR is suitable for many standard oscillator circuits, ensuring efficient operation.
• Series: 1X – The series designation often refers to a specific product line or family from the manufacturer, indicating a particular set of characteristics or performance benchmarks. The ‘1X’ series from SCTF signifies a reliable and well-engineered crystal suitable for general-purpose applications.
• Frequency: 25MHz – This is the fundamental operating frequency of the crystal. A 25MHz frequency is commonly used in numerous digital systems, providing a solid clock base for microcontrollers, communication modules, and data processing units.
• Size (mm): 2.0×1.6×0.45 – This ultra-compact dimension highlights the crystal’s small footprint, making it ideal for miniaturized electronic devices where board space is at a premium. Its low profile of 0.45mm is particularly beneficial for thin devices.
• Mounting Type: Surface Mount – Surface Mount Technology (SMT) allows for automated assembly, reducing manufacturing costs and increasing production efficiency. This type of mounting is standard in modern electronics, enabling compact designs and high-density PCB layouts.
• Component Type: Crystal – This specifies that the device is a passive crystal resonator, which relies on the piezoelectric effect to generate a stable frequency when integrated into an appropriate oscillator circuit.
• Package / Case: 4-SMD – The 4-SMD (Surface Mount Device) package indicates that the crystal has four solderable pads for mounting onto a printed circuit board. This widely adopted package type ensures compatibility with standard SMT assembly processes.
• Frequency Range: 16-54MHz – While this specific crystal operates at 25MHz, the stated frequency range indicates the broader capability of the ‘1X’ series or similar crystals from SCTF. This context helps designers understand the potential for other frequencies within the same family.
• Load Capacitance: 12pF – Load capacitance is the external capacitance required by the oscillator circuit to make the crystal oscillate at its specified frequency. A 12pF load capacitance is a common value, ensuring compatibility with many standard ICs designed for crystal oscillators.
• Frequency Stability: ±30ppm – Frequency stability refers to how much the output frequency can drift over a specified temperature range or time. A stability of ±30ppm (parts per million) indicates a high degree of precision, suitable for applications where consistent timing is critical, such as communication systems or industrial controls.
• Frequency Tolerance: ±10ppm – Frequency tolerance specifies the maximum deviation of the crystal’s actual frequency from its nominal frequency at a specific reference temperature (usually 25°C). A ±10ppm tolerance is excellent, ensuring very accurate initial frequency output.
• Operating Temperature: -40℃ to +85℃ – This wide operating temperature range signifies the crystal’s robustness and suitability for harsh environments, including industrial, automotive, and outdoor applications where extreme temperatures may be encountered.
