The S3D19.200000B20F30T with SMD Oscillators is a RoHS compliant, 19.2MHz ±20ppm Tuning Fork Crystal oscillator, manufactured by SCTF. The size of the component is 3225-4P SMD (Surface Mount Device) which requires four-terminal technology for mounting on the printed circuit board. It features a standard frequency tolerance of ±20ppm, operating temperature of -20°C~70°C, and operating voltage of 5V. The XO oscillator combines the quartz crystal resonator and the transistor circuit together, and uses frequency phase shift to realize oscillation. It is widely used in communication equipment, consumer electronic equipment, instruments and various other types of equipment.
