This device falls under the category of Quartz Crystal Oscillators and is specifically designed for surface-mount applications, providing a precise and stable clock signal essential for the operation of various digital circuits. As a fundamental timing component, it generates an oscillating electrical signal at a specific frequency, which acts as the ‘heartbeat’ for microcontrollers, microprocessors, and other synchronous digital systems, ensuring their coordinated operation.

Key Specifications

This crystal oscillator boasts several critical specifications that define its performance and suitability for diverse applications. The ‘Output’ type is CMOS, which stands for Complementary Metal-Oxide-Semiconductor. CMOS output is widely used due to its low power consumption, high noise immunity, and compatibility with a broad range of digital logic families, making it ideal for modern electronic designs. The ‘Series’ designation is 3C, indicating a specific product line or family from SCTF, which often implies certain performance characteristics or packaging styles. The core ‘Frequency’ of this oscillator is 33MHz, meaning it generates 33 million cycles per second, a common frequency for many digital communication and processing tasks. Its compact ‘Size (mm)’ of 3.2×2.5×0.95 makes it suitable for space-constrained applications, reflecting the trend towards miniaturization in electronics. The ‘Input Current’ range of 10-40mA specifies the typical current draw required for its operation, which is important for power budget calculations. As a ‘Surface Mount’ component, it is designed for automated assembly processes, reducing manufacturing costs and increasing reliability compared to through-hole components. The ‘Component Type’ is clearly a Crystal Oscillator, distinguishing it from simple crystals or resonators by its integrated oscillating circuit. The ‘Package / Case’ is a 4-SMD, referring to its four-pin surface-mount device package, which facilitates easy integration onto printed circuit boards. It supports a versatile ‘Supply Voltage’ range of 1.8V, 2.5V, and 3.3V, offering flexibility for integration into systems with different power rails. The ‘Frequency Range’ of 1 – 160MHz indicates the broader family’s capability, while this specific part operates at 33MHz. ‘Frequency Stability’ of ±50ppm (parts per million) and ‘Frequency Tolerance’ of ±20ppm are crucial metrics, defining how much the actual output frequency can deviate from the nominal 33MHz under varying conditions and during manufacturing, respectively. These values are vital for applications requiring precise timing. Finally, the ‘Operating Temperature’ range is exceptionally wide, spanning from -40℃ to +85℃, -40℃ to +105℃, and -40℃ to +125℃, indicating its robustness and suitability for harsh industrial, automotive, and high-temperature environments.
