Its compact 4-SMD package makes it ideal for space-constrained applications, while its robust specifications ensure reliable performance across a wide range of operating conditions. As a passive component, it plays a critical role in frequency control, translating electrical energy into mechanical vibrations and back again to generate a precise frequency output.

Key Specifications

• ESR (Equivalent Series Resistance): 200Ω
  ESR represents the total resistive impedance of the crystal when it’s oscillating. A lower ESR generally indicates a more efficient crystal that requires less drive power and starts up more easily. For this crystal, an ESR of 200Ω is a typical value for its frequency range and package size, ensuring stable oscillation in most standard oscillator circuits.
• Series: 1X
  The ‘1X’ series designation often refers to a specific product family or performance tier from the manufacturer SCTF. This series is designed for general-purpose applications where a balance of performance, size, and cost is critical, making it suitable for a broad array of electronic designs.
• Frequency: 16.384MHz
  This is the nominal operating frequency at which the crystal is designed to resonate. 16.384MHz is a common frequency, often chosen for its divisibility by powers of two, making it convenient for generating standard baud rates in communication systems or precise timing intervals in digital logic.
• Size (mm): 2.0×1.6×0.45
  These dimensions indicate a very compact footprint, measuring 2.0mm in length, 1.6mm in width, and a remarkably low profile of 0.45mm in height. This ultra-small size is crucial for miniaturized electronic devices, wearable technology, and high-density PCB layouts where space is at a premium.
• Mounting Type: Surface Mount
  Surface Mount Technology (SMT) allows the component to be mounted directly onto the surface of a printed circuit board (PCB). This method facilitates automated assembly, reduces manufacturing costs, and enables higher component density compared to through-hole components.
• Component Type: Crystal
  This confirms that the device is a quartz crystal, which utilizes the piezoelectric effect to produce a stable oscillating frequency. Crystals are known for their superior frequency stability and accuracy compared to ceramic resonators or LC oscillators.
• Package / Case: 4-SMD
  The 4-SMD package indicates that the crystal has four solderable pads for surface mounting. This standard package type is widely used for miniature crystals, providing a robust and reliable connection to the PCB.
• Frequency Range: 16-54MHz
  This specifies the broader range of frequencies for which this particular crystal series or design architecture is suitable. While this specific part is 16.384MHz, the series can accommodate other frequencies within this range.
• Load Capacitance: 12pF
  Load capacitance is the total capacitance seen by the crystal from the oscillator circuit. For optimal performance and to ensure the crystal oscillates at its specified frequency, the external load capacitance of the circuit must match this value. A 12pF load capacitance is common for fundamental mode crystals in digital applications.
• Frequency Stability: ±30ppm
  Frequency stability indicates how much the crystal’s output frequency can deviate from its nominal value over its operating temperature range, aging, and other environmental factors. A ±30ppm stability is excellent for many commercial and industrial applications, ensuring consistent timing performance.
• Frequency Tolerance: ±10ppm
  Frequency tolerance specifies the maximum allowable deviation of the crystal’s actual frequency from its nominal frequency at a specific reference temperature (usually 25°C). A ±10ppm tolerance signifies high initial accuracy, making this crystal suitable for applications requiring precise timing from the outset.
• Operating Temperature: -40℃ to +85℃
  This wide operating temperature range ensures the crystal performs reliably in harsh environments, from extreme cold to significant heat. This makes it suitable for industrial, automotive, and outdoor applications where temperature variations are common.

This crystal can serve as the reference clock for frequency synthesizers, ensuring stable carrier frequencies and reliable data transmission and reception.
• Real-Time Clocks (RTCs): While 16.384MHz is not a standard RTC frequency, it can be easily divided down to generate precise 1Hz signals or other timing intervals required by RTC circuits, providing accurate timekeeping in devices like data loggers, smart meters, and automotive infotainment systems.
• Digital Signal Processing (DSP): DSP applications, especially those involving audio or video processing, often require precise sampling rates and clocking. This crystal can provide the stable timing necessary for analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), ensuring high-fidelity signal processing.
• USB Interface Timing: Many USB controllers require a precise clock source for proper data transfer rates. A 16.384MHz crystal can be used as a base frequency, which can then be multiplied or divided to achieve the required USB clock frequencies, ensuring reliable communication between devices.
