402F19211CDT Application Field and Working Principle

The 402F19211CDT is a type of crystal resonator, which is widely used in electronic devices as clock generator and timing devices. A crystal resonator is a type of active component that is used for frequency control and stability in electrical circuits, typically in the frequency ranges of 10kHz to 30MHz. This type of resonator is typically made of quartz, known for its high stability and reliability.

In electronic devices, the 402F19211CDT crystal resonator functions as the main oscillator, a frequency-determining component of the circuit that oscillates at a set frequency. By providing the oscillation signal, the crystal resonator characterizes the frequency of the signal and determines the frequency of the electrical waveforms. It can prevent signal distortions due to frequency shifts.

In the case of the 402F19211CDT, it works on the same principle as other crystal oscillators and is mainly used in communication systems and audio systems. This crystal resonator has a frequency stability of ± 30 ppm and an operating temperature range from -30°C to 85°C. It can maintain the oscillation signal over a wide temperature range, thus providing a reliable and stable frequency.

When the 402F19211CDT crystal resonator is put into operation, it vibrates at a frequency determined by its physical dimension. This type of crystal resonator is made of quartz, which has a high dielectric constant, as well as a high mechanical stability and a great temperature stability. When an electric current is passed through the crystal, it causes a mechanical vibration and the resonator starts to oscillate at the determined frequency.

However, in order to achieve a stable oscillation, an external electric circuit must be used to provide a feedback loop to the crystal. This loop ensures that the crystal oscillates at the defined frequency and is adjusted by the surrounding electronic components. In the case of the 402F19211CDT crystal resonator, the operating temperature range can be extended by using temperature compensation techniques.

The 402F19211CDT crystal resonator is an important component in many electronic circuits, as it ensures accurate timing, frequency stability and precision. Its wide operating temperature range and high frequency stability make it a great choice for many applications. For applications such as communication systems, audio systems and timing devices, the 402F19211CDT crystal resonator is the preferred choice.
