This compact 4-SMD crystal is a fundamental frequency-control device, essential for generating stable clock signals in a wide array of electronic circuits. Crystals like the SX1B19.200F0810F30 operate on the principle of piezoelectricity, converting mechanical vibrations into electrical signals at a very precise frequency. This particular model is designed for applications demanding high accuracy and reliability within a compact footprint, making it an ideal choice for modern, miniaturized electronic designs where space is at a premium and stable timing is critical.

Key Specifications

ESR (Equivalent Series Resistance): 200Ω
ESR is a critical parameter that indicates the crystal’s internal resistance at its resonant frequency. A lower ESR generally signifies a more efficient crystal that requires less drive power and can start up more reliably. An ESR of 200Ω for this crystal indicates its electrical characteristics and helps designers match it with appropriate oscillator circuits to ensure stable operation and optimal performance.

Series: 1X
The ‘1X’ series designation typically refers to the crystal’s fundamental mode of operation. This means the crystal oscillates at its primary, lowest resonant frequency, rather than an overtone. Fundamental mode crystals are generally easier to design with and offer better stability and lower phase noise compared to overtone crystals, simplifying circuit design and ensuring a cleaner clock signal.

Frequency: 19.2MHz
This is the nominal operating frequency of the crystal. A 19.2MHz frequency is commonly used in various digital communication systems, microcontrollers, and wireless applications, providing a stable timing reference for high-speed data processing and accurate signal generation. The precision of this frequency is crucial for the correct operation of timing-sensitive circuits.

Size (mm): 2.0×1.6×0.45
This ultra-compact dimension highlights the miniaturization of this component. A 2.0mm by 1.6mm footprint with a mere 0.45mm height makes it suitable for highly space-constrained applications such as wearables, portable devices, and high-density PCBs. This small form factor contributes significantly to the overall size reduction of end products.

Mounting Type: Surface Mount
Surface Mount Technology (SMT) is the industry standard for automated PCB assembly. Surface mount components like this 4-SMD crystal allow for efficient, high-volume manufacturing, reducing production costs and increasing board density compared to through-hole components. This also contributes to improved mechanical stability and vibration resistance.

Component Type: Crystal
This explicitly identifies the device as a crystal resonator, distinguishing it from oscillators (which include internal oscillating circuitry) or resonators (which might be ceramic). Crystals offer superior frequency stability and accuracy due to their precise quartz material and manufacturing processes, making them preferred for applications requiring tight timing tolerances.

Package / Case: 4-SMD
The 4-SMD package indicates a standard surface-mount enclosure with four solderable pads. This package type is widely recognized and supported by automated pick-and-place machines, ensuring compatibility with standard PCB assembly processes and providing reliable electrical and mechanical connections.

Frequency Range: 16-54MHz
While this specific crystal operates at 19.2MHz, the stated frequency range indicates the broader family or series capability. This information is useful for designers looking for similar components within a specific frequency band, suggesting that SCTF offers a range of crystals suitable for diverse timing requirements within this spectrum.

Load Capacitance: 8pF
Load capacitance is the total capacitance seen by the crystal from the external circuit. An 8pF load capacitance is a common value for many crystal oscillators, indicating that the crystal is designed to operate optimally when paired with external capacitors of this value to achieve its specified nominal frequency and stability. Matching this value is crucial for accurate frequency generation.

Frequency Stability: ±30ppm
Frequency stability defines how much the crystal’s output frequency can deviate from its nominal value over a specified temperature range, aging, and other environmental factors. A stability of ±30ppm (parts per million) is a good indicator of its performance, ensuring reliable timing for applications where moderate frequency drift is acceptable over varying conditions.

Frequency Tolerance: ±10ppm
Frequency tolerance specifies the maximum allowable deviation from the nominal frequency at a specific reference temperature (usually 25°C). A tolerance of ±10ppm signifies high initial accuracy, meaning the crystal’s actual frequency will be very close to 19.2MHz when it is first manufactured and measured, which is vital for precise timing applications.

Operating Temperature: -40℃ to +85℃
This wide operating temperature range indicates the crystal’s robustness and suitability for industrial and automotive applications, as well as consumer electronics that may be exposed to extreme environmental conditions. The crystal is guaranteed to perform within its specified parameters across this broad temperature spectrum, ensuring reliability in diverse operational environments.
