Crystals: 7M48000003 application field and working principle

Crystals are materials with a regular arrangement of atoms or molecules, providing a uniform shape and size. Their ability to oscillate, or resonate under the influence of external electrical or magnetic fields, is widely utilized. In this article, we will focus on one type of crystal, 7M48000003, and its applications as well as the mechanism of its operation. 7M48000003, also known as an oscillator quartz crystal, is the most commonly used type of crystal for oscillator circuits. These crystals are widely used in quartz clock oscillators, wired circuits, automated computer and electronics systems and related communication components. They deliver high-quality performance and exceptional accuracy, from many types of systems and technologies. The 7M48000003 is formed from two quartz plates sandwiched together with a thin layer of metal between them. Each plate contains a pair of electrodes that act as a transducer, converting electric energy into mechanical energy and vice versa. The quartz plates are cut into the required frequency, and the amount of electric charge derived from the electrodes determines the frequency of vibration and the frequency of the oscillator circuit.The operation principle of 7M48000003 is based on the piezoelectric effect of quartz. When electric fields are applied to the quartz crystal, the crystal structure is distorted, and the mutual attraction of the atoms is enhanced. This increases the electrical resistance and therefore increases the current flowing through the crystal. As electric current flows, the quartz plates oscillate at a consistent frequency and generate an alternating current with a frequency determined by the type of quartz and the amount of electrical charge applied.Another important application of 7M48000003 is temperature compensation. This involves adding a temperature-sensing device, such as a thermistor, to a quartz crystal oscillator circuit. The thermistor provides feedback to the oscillator, changing the value of the electrical charge applied to the crystal. This enables the oscillator to maintain its frequency despite changes in temperature.In addition, 7M48000003 can also be used for network-based systems and communication components, providing accurate and reliable frequency control signals. This can be used to maintain the stability of communication networks, ensure reliable data transmission and increase the speed of transmission.Overall, 7M48000003 is a versatile and dependable quartz crystal that is widely found in automated computer and electronic systems, wired circuits and related communication components. Its ability to vibrate at a consistent frequency and its capacity to provide temperature compensation make it a valuable tool for anyone who needs to maintain accuracy and reliability.
