Crystals: ECS-49-20-18-TR Application Field and Working Principle

Crystals are widely used in many devices and circuit processes, and are indispensable components in the development of circuits with high frequency stability and sensitivity. Among them, ECS-49-20-18-TR is a type of crystal that is highly sought after by engineers and electronics hobbyists. This article will introduce the application field and working principle of ECS-49-20-18-TR crystal.First, let\'s look at the application field of ECS-49-20-18-TR crystal. This type of crystal has a wide frequency range from 16 MHz to 40 MHz and can be used for many electronic circuits. For example, in the communication field, it is often used for communication transmitters and receivers\' frequency synthesis. Besides, it can also be used in many physical devices, such as cellular phones, TVs, radios, clocks, etc. to produce various oscillations and stabilize specific frequencies.Then, let’s look at the working principle of ECS-49-20-18-TR crystal. In general, a crystal is made up of two pieces of simple structures and sandwich them with a clamper and a setting plate. The plates are made up of piezoelectric materials, such as quartz, that could transform the electric energy into a certain frequency of mechanical vibration and vice versa. When the drive signal is input, the plates will vibrate at a certain frequency and they produce an alternating electrical signal with that same frequency. Through the resonance of this frequency, the crystal will be able to precisely maintain the driving frequency of the signal, which is vital in order to accurately control and convert electric energy in a circuit. To sum up, ECS-49-20-18-TR crystal is a type of crystal with the application field of communication transmitters and receivers’ frequency synthesis, cellular phones, TVs, radios, clocks, and other electric equipments. It works by transforming electric energy into a mechanical vibration with a certain frequency and then, through the resonance of the frequency, precisely maintain the driving frequency of the signal.
