IntroductionFixed Inductors are one of the essential components in a huge variety of electronic circuits, such as power supplies, audio amplifiers and many more. The CW252016-R22J is an innovative and high-efficiency fixed inductor which is available in a range of sizes and shapes. This particular inductor was specifically designed to offer a great balance between performance, cost and size. Application FieldThe CW252016-R22J fixed inductor is ideally suited for applications such as high frequency voltage regulator modules (VRMs), DC-DC converters, on-chip power delivery systems and multiple-output step-down DC-DC converters, among many others. Its outstanding features, such as its small form factor, high power handling capacity, low leakage inductance and good temperature performance, enable it to be used in a wide range of applications. Moreover, this inductor is a great choice for applications that require high efficiency because of its low profile and its excellent saturation behavior. It also offers excellent regulation characteristics as well as low quiescent current, making it suitable for a wide variety of power circuits. Working PrincipleThe CW252016-R22J inductor works by generating a magnetic field, which is then converted into an electrical signal. The inductor is made up of a coil of wire wrapped around a metal core. This core is composed of ferromagnetic material such as iron or steel, which gives the inductor its magnetic properties. When an alternating current is applied to the inductor, it induces an electro-magnetic field in the metal core. This field changes with the changing current and this induces a voltage in the coil. This voltage is then used to power circuits or to store energy. The inductance of the inductor is determined by the number of turns in the coil and the size and shape of the core. ConclusionThe CW252016-R22J fixed inductor is an ideal choice for applications that require high efficiency, low profile and good temperature and power handling performance. Its core is composed of a ferromagnetic material and its coil is wrapped around a metal core. The specific number of turns in the coil and the size and shape of the core determine the inductance of the inductor. This inductor is suitable for a wide range of power circuits, specifically DC-DC converters, voltage regulator modules and multiple-output step-down DC-DC converters, among many others.
