Crystals: 7B25020003 Application Field and Working Principle

Crystals are a fascinating and complex part of modern electronics. Used for everything from watches to computers and even microwave ovens, these devices offer their users amazing capabilities, both in terms of their technology and the sheer ability to create and manipulate vibrations. The 7B25020003 is one such crystal, and is used in many applications in modern day life.The 7B25020003 is an overtone crystal, meaning it is used to create oscillations or vibrations over a range of frequencies while offering a large dynamic range, as well as low phase noise levels. This make the 7B25020003 perfect for use as a frequency reference for many types of electronic components. Furthermore, it offers thermal stability with an operating temperature range of -40°C to +85°C, and is manufactured with a tolerance of +/-20ppm.The 7B25020003 is designed with a rugged construction suited to applications such as vehicular power systems. It is constructed with six pins, four of which are insulated with a hermetic seal. The length of the crystal is 4.35mm, with a width of 2.5mm, creating a very compact and efficient device.The main applications of the 7B25020003 crystal are frequency control and signal generation. It can be used in precision oscillators, quartz crystal oscillators, radio receivers and transmitters, as well as a variety of different signal generation and signal distribution products. The 7B25020003 is therefore used in a wide range of products, from wireless laptops, to wireless routers and radios, to medical imaging machines.The working principle of the 7B25020003 is based upon the quartz resonance phenomenon, with the crystal acting as a feedback element within an electrical circuit. When voltage is applied, the crystal’s structure flexes and this causes a change in the capacitance between two contacts and the crystal’s resonant frequency will change. This flexing of the crystal’s structure produces an electrical voltage waveform, which is then used to generate a signal.The 7B25020003 is an excellent example of how a complex yet robust device can be used to produce a wide range of frequencies, while remaining both efficient and cost effective. Thanks to its compact size and its ability to generate and manipulate signals, it is found in many applications across a broad span of industries. With its wide range of features, the 7B25020003 is an invaluable part of any modern day electronics system.
