Abstract: The article will narrate the application field and working principle of the 402F27133CKR crystal, which has a wide range of applications including the generation of multivibrators and in several voltage regulator circuits.

Introduction

The 402F27133CKR crystal is an oscillator crystal used to maintain a stable and precise frequency in electronic circuitries where an accurate frequency needs to be maintained. A working oscillator is a circuit consisting of two capacitors, two resistors, and a crystal. When an alternating current signal is supplied to the circuit, the crystal produces an output signal having the same frequency as that of the input. This crystal is used in applications requiring precise frequency control such as multivibrator circuits, voltage regulator circuits, oscillator circuits, low power radio applications and other frequency-controlled communication systems.

Working principle

The 402F27133CKR crystal works on the principle of piezoelectricity. It is a passive device made up of a piezoelectric material such as quartz or some other specialized ceramic material which can generate a specific alternating current signal when a voltage is applied across it. This alternating current generated by the crystal has a precise frequency, determined by its physical properties. The resonator circuit, consisting of an amplifier and the crystal, is used to control the output signal frequency. When the output signal frequency is different from the crystal’s frequency, the resonance decreases, leading to a decrease in the current output from the crystal. This resonant frequency also known as the “characteristic frequency” is maintained by adjusting the frequency of the input signal and the external components present in the circuit.

Application field

Due to its precise frequency control capability and wide frequency range, the 402F27133CKR crystal has a wide range of applications. It is used to generate multivibrators, which are electronic circuits that oscillate between two states based on their internal timing. This crystal is also used in voltage regulator circuits to maintain a precise voltage supply. Other applications include clock generators, frequency synthesizers, and as a reference oscillator in various communication systems.

Conclusion

The 402F27133CKR crystal is an oscillator crystal used to maintain a precise frequency in multiple applications. It works on the principle of piezoelectricity and is used to generate multivibrators, voltage regulator circuits, clock generators and other communication related devices. Its wide frequency range and precise frequency control capability have made it popular in several electronic circuitries.
