Crystals

Crystals are objects that can convert energy from all kinds of different forms, including light, sound, electrical, and magnetic, into a coherent pulse. Crystals can be used to create filters, amplifiers and oscillators, and are essential components in many digital electronics, such as computers, radios, and cell phones. Among them, LFXTAL002995BULK is a type of crystals with its own application field and working principle.

Application Field of LFXTAL002995BULK

LFXTAL002995BULK is a type of quartz crystals available in 3.2* and 5.0* Mhz applications. It provides high stability, excellent accuracy, and low power consumption in a wide range of temperatures, making it an ideal choice when building high-precision frequency related products. It can be used in many applications, such as radio frequency oscillators, echo generators, telecommunications, industrial automation, alarm systems, and audio circuitry, etc. It can also be used as a clock or synchronous generator for digital circuits and precision frequency-measuring instruments.

Working Principle of LFXTAL002995BULK

The working principle of LFXTAL002995BULK is based on the piezoelectric effect. The quartz crystal enclosed in the holder works as a mechanical resonator that creates an alternating mechanical gate. This gate creates a voltage which is about 0.1 volts square wave. When the crystal is in a certain frequency range, the gate vibrates and creates an alternating electric current from the electrodes. The oscillation of this kind is sustained by the internal capacitance and resistance of the crystal.

The frequency of oscillation is determined by the thickness of the quartz and its intrinsic physical characteristics, such as its Young’s Modulus, stiffness, and dissipation of energy. When the crystal is not exposed to any external stress, the quartz damps out the vibration and the frequency remains constant. The frequency of oscillation can be adjusted by means of slicing, cutting, or optically polishing the flat surfaces of the Quartz while taking care to protect them from contamination and moisture.

A properly cut quartz crystal will oscillate at a certain predetermined frequency, depending on its size and mechanical properties. The crystal is capable of sustaining the predetermined frequency over a wide range of temperatures, indicating its stability and high accuracy. With its low power consumption and high stability in various temperature ranges, LFXTAL002995BULK is perfectly suited for a variety of applications.
