Its robust design and excellent electrical characteristics make it an ideal choice for demanding electronic designs requiring accurate timing.

Key Specifications

The SX0B48.000F1010F30 crystal boasts several key specifications that define its performance and suitability for various applications:

• ESR (Equivalent Series Resistance): 80Ω – The ESR indicates the crystal’s internal resistance at resonance. A lower ESR generally signifies a higher quality crystal with better Q-factor, leading to more efficient oscillation and lower power consumption in the oscillator circuit. An 80Ω ESR is typical for this frequency range and package size, ensuring stable operation.
• Frequency: 48MHz – This is the nominal operating frequency at which the crystal resonates. A 48MHz frequency is commonly used in microcontrollers, communication modules, and data processing units that require high-speed clocking for their internal operations.
• Size (mm): 1.6×1.2×0.35 – This ultra-compact dimension highlights the crystal’s small footprint, making it ideal for miniaturized electronic devices where board space is at a premium. The low profile of 0.35mm is particularly beneficial for thin devices and multi-layer PCBs.
• Mounting Type: Surface Mount – This specifies that the component is designed for surface mount technology, allowing for automated pick-and-place assembly, which is crucial for high-volume manufacturing and cost-effective production.
• Package / Case: 4-SMD – The 4-SMD package indicates a four-pin surface mount device. This standard package provides robust mechanical and electrical connections to the PCB, ensuring reliable long-term performance.
• Frequency Range: 24-54MHz – While this specific crystal operates at 48MHz, the broader frequency range indicates the family of crystals it belongs to, showcasing SCTF’s capability to produce crystals across a useful spectrum for various applications.
• Load Capacitance: 10pF – The load capacitance is the external capacitance required by the oscillator circuit to make the crystal oscillate at its specified series or parallel resonant frequency. A 10pF load capacitance is a common value, simplifying circuit design with standard ICs.
• Frequency Stability: ±30ppm – Frequency stability defines how much the crystal’s operating frequency can deviate from its nominal value over a specified temperature range. A ±30ppm stability over the -40℃ to +85℃ range indicates excellent performance, crucial for applications requiring consistent timing across varying environmental conditions.
• Frequency Tolerance: ±10ppm – This specifies the maximum allowable deviation of the crystal’s actual frequency from its nominal 48MHz value at room temperature (typically 25℃). A ±10ppm tolerance is a tight specification, ensuring high initial accuracy for critical timing applications.
• Operating Temperature: -40℃ to +85℃ – This wide operating temperature range signifies the crystal’s suitability for industrial and automotive applications, as well as consumer electronics, where devices might be exposed to extreme hot or cold environments while maintaining performance.
