SX0B26.000F1210F30 26MHz ±10ppm 4-SMD Crystal

SX0B26.000F1210F30 is a high-precision 26MHz surface-mount crystal manufactured by SCTF, a reputable name in the production of passive electronic components. This crystal is designed to provide a stable and accurate frequency reference, which is crucial for the reliable operation of various electronic circuits. As a fundamental component in the timing and synchronization of digital systems, this 4-SMD crystal converts electrical energy into mechanical vibrations and back again, resonating at a very specific frequency. Its compact size and robust design make it suitable for integration into miniaturized electronic devices where space is at a premium, ensuring precise timing for microcontrollers, wireless communication modules, and other frequency-dependent applications.

Key Specifications

This SCTF crystal boasts several critical specifications that define its performance and suitability for diverse applications:

• ESR (Equivalent Series Resistance): 200Ω – The ESR indicates the internal resistance of the crystal. A lower ESR generally means the crystal requires less power to oscillate and can start up more quickly. While 200Ω is a common value for miniature crystals, it’s important for designers to ensure their oscillator circuit can drive this resistance effectively to maintain stable oscillation.
• Series: 0X – This typically refers to the product series or family within the manufacturer’s catalog. It helps in identifying specific design characteristics or performance tiers associated with that series.
• Frequency: 26MHz – This is the nominal operating frequency at which the crystal is designed to resonate. A 26MHz frequency is commonly used in various wireless communication protocols, microcontrollers, and digital signal processing applications requiring a precise clock source.
• Size (mm): 1.6×1.2×0.35 – This ultra-compact dimension highlights the crystal’s suitability for high-density PCB layouts and miniaturized electronic devices such as wearables, IoT sensors, and mobile communication modules. Its small footprint is a significant advantage in modern electronics design.
• Mounting Type: Surface Mount – Surface Mount Device (SMD) technology allows for automated assembly, reducing manufacturing costs and increasing production efficiency. This mounting type is standard for modern electronic components, enabling compact designs and improved performance due to shorter signal paths.
• Component Type: Crystal – This confirms the fundamental nature of the component as a passive device that generates a precise frequency when excited by an external circuit.
• Package / Case: 4-SMD – The 4-SMD package indicates the physical form factor and the number of pins (or pads) for surface mounting. This standard package ensures compatibility with automated pick-and-place machines and reflow soldering processes.
• Frequency Range: 24-54MHz – While the nominal frequency is 26MHz, this range indicates that the crystal belongs to a family of devices capable of operating within this broader spectrum, offering context to its design capabilities.
• Load Capacitance: 12pF – Load capacitance is critical for tuning the crystal to its exact specified frequency. The external capacitance in the oscillator circuit must match this value to ensure the crystal oscillates precisely at 26MHz. Mismatched load capacitance can lead to frequency deviation.
• Frequency Stability: ±30ppm – Frequency stability measures how much the crystal’s frequency can drift over its operating temperature range. A stability of ±30ppm (parts per million) is a good indicator of reliable performance across varying environmental conditions, ensuring consistent timing.
• Frequency Tolerance: ±10ppm – Frequency tolerance specifies the maximum allowable deviation from the nominal frequency at a specific reference temperature (usually 25°C). A ±10ppm tolerance signifies high initial accuracy, which is essential for applications requiring tight frequency control.
• Operating Temperature: -40℃ to +85℃ – This wide operating temperature range demonstrates the crystal’s robustness and suitability for industrial, automotive, and outdoor applications where extreme temperatures are common. It ensures reliable performance in harsh environments.
