Crystals

Crystals are components of electrical or mechanical systems that use electrical energy to create frequency-dependent oscillations. Crystals are used in various technologies such as watches, communication systems, and computing devices. In these systems, they act as oscillators or filters that accurately control the frequency of current or voltage changes.FA-20H 40.0000MF15Z-AC is a type of crystal that is used in various fields. It is a low-cost, compact and high-quality device that is used in portable devices such as mobile phones and personal digital assistants (PDAs). It has a center frequency of 40 MHz, a low power consumption, and can operate from -40 to 85 °C.The main application of FA-20H 40.0000MF15Z-AC is in mobile telecommunication base-stations. In these systems, it is used as a frequency-dependent filter that accurately controls the frequency of signals that are transmitted and received. This ensures the efficient leveraged use of the frequency spectrum for communication services. Additionally, it can be used for testing the functions of base-stations and antennas.In terms of its working principle, the FA-20H 40.0000MF15Z-AC acts as an energy storage device. It stores energy when an electric current is passed through it, and this energy is released as an oscillating electric output. This output is then used to deliver a stable frequency signal to other components in the system. The FA-20H 40.0000MF15Z-AC is a high-precision device that has a small temperature drift and can maintain a very tight tolerance for a long period of time without any external adjustments. It consists of three parts: a base metal, a passive device, and a resonator. The base metal forms the skeleton of the device, while the passive device is essentially an external energy source. Finally, the resonator is composed of a metal core that is coated by an oxide film. This oxide film is the key feature of the crystal as its two sides act as electrodes when a current is passed through it. The current passes through the crystal at a specific frequency, resulting in a quartz crystal resonator that vibrates and creates a particular frequency within a predefined range. The frequency of this current is also known as the resonant frequency of the device.The FA-20H 40.0000MF15Z-AC is also capable of handling a wide range of temperatures and voltage stabilities, making it ideal for use in highly demanding applications such as in aerospace and defense. It is a highly reliable device that is resistant to vibration shock, dust and sand. Overall, the FA-20H 40.0000MF15Z-AC is a highly precise, robust and reliable type of crystal that is capable of maintaining a tight tolerance for a long period of time. It is used in a wide variety of applications from consumer electronics to aerospace and defense, making it ideal for various industries. Furthermore, due to its low power consumption and low temperature drift, it is considered to be the crystal of choice for most applications.
