Key Specifications

The SX1B40.000F0810F30 crystal boasts several critical specifications that define its performance and suitability for diverse applications:

• ESR (Equivalent Series Resistance): 50Ω – The ESR indicates the crystal’s internal resistance. A lower ESR generally signifies a higher quality crystal with better oscillation characteristics and lower power consumption, making it easier for oscillator circuits to start and maintain stable oscillation.
• Series: 1X – This refers to the crystal series, often indicating a specific product line or design characteristic from the manufacturer. It helps in identifying the crystal within SCTF’s broader portfolio.
• Frequency: 40MHz – This is the fundamental operating frequency of the crystal, meaning it generates a precise 40 million cycles per second. This high frequency is suitable for applications requiring fast processing speeds and accurate timing.
• Size (mm): 2.0×1.6×0.45 – These dimensions highlight the crystal’s ultra-compact footprint, making it ideal for miniaturized electronic devices where board space is at a premium. The low profile of 0.45mm is particularly beneficial for thin designs.
• Mounting Type: Surface Mount – This specifies that the crystal is designed for surface mount technology (SMT), allowing for automated assembly processes, reduced manufacturing costs, and higher component density on printed circuit boards (PCBs).
• Component Type: Crystal – This confirms its function as a passive component that utilizes the piezoelectric effect to create an electrical signal with a very precise frequency. It is the core element for generating clock signals.
• Package / Case: 4-SMD – The 4-SMD package indicates a four-pin surface mount device. This standard package type ensures compatibility with common SMT assembly equipment and provides robust electrical and mechanical connections.
• Frequency Range: 16-54MHz – This attribute specifies the broader range of frequencies for which this particular crystal series or design is typically available. While this specific part is 40MHz, the range indicates the versatility of the underlying crystal technology.
• Load Capacitance: 8pF – Load capacitance is the external capacitance required by the oscillator circuit to make the crystal oscillate at its specified frequency. An 8pF load capacitance is relatively low, often preferred in designs where minimal external components are desired or where specific oscillator ICs are used.
• Frequency Stability: ±30ppm – Frequency stability defines how much the crystal’s operating frequency can deviate from its nominal value over a specified temperature range, aging, and supply voltage variations. A ±30ppm stability ensures reliable performance under varying environmental conditions.
• Frequency Tolerance: ±10ppm – Frequency tolerance is the maximum allowable deviation of the crystal’s actual frequency from its nominal frequency at a specific reference temperature (usually 25°C). A tight tolerance of ±10ppm indicates high initial accuracy, crucial for precise timing applications.
• Operating Temperature: -40℃ to +85℃ – This wide operating temperature range signifies the crystal’s robustness and suitability for industrial, automotive, and outdoor applications where extreme temperatures can be encountered, ensuring consistent performance across diverse environments.
