It is widely used in oscillators, electronic instruments, watches, and communication equipment. Moreover, it can be used in medical instruments and other precision control mechanisms that require stable and accurate frequency output.

Working Principle of 402F40033CJT

The 402F40033CJT uses a quartz crystal as its major components to realize oscillation. Quartz crystal was used because of its stable and reliable frequency of vibration. It does not change with the environment and temperature, which helps to ensure a highly accurate frequency output. Moreover, quartz crystal has superior repeatability, which enable the unit to maintain an accurate frequency output for a long period of time.

The 402F40033CJT uses an oscillator circuit with a tuning-fork vibration type oscillator to increase accuracy and repeatability. The oscillator circuit works by generating a sinusoidal waveform which is processed by a microcontroller that applies a saw-tooth waveform to the quartz crystal to make it vibrate at a certain frequency. The frequency output is then monitored and adjusted by the oscillator circuit to maintain accuracy. This process is repeated until the desired frequency output is achieved.
