＜div＞＜h1＞Fixed Inductors＜/h1＞＜p＞Fixed inductors are components found in electrical and electronic devices. These components are used to store electrical energy in the form of a magnetic field. Fixed inductors are also known as energy storage inductors, primary inductors, power inductors, and chokes. They are usually used as filters, to filter out high frequency signals or noise, or to provide a relatively constant current to an inductive load. Fixed inductors are essential components in a device\'s electrical circuit and they provide a great amount of protection, when these components are incorporated properly.＜/p＞＜p＞A fixed inductor consists of an inductor core made of iron, ferrite, or air and a coil of wire wrapped around it. An AC voltage is applied to the coil, and the core material inside the coil increases the strength of the resulting magnetic field. The number of turns in the coil determines the amount of magnetic field generated and the characteristics of the resulting inductance. The inductance of an inductor is the ratio of the number of turns in the coil. Upon the application of an electrical current, the fixed inductor stores this energy in the form of a magnetic field. In the case of an AC current, the inductor stores some of this energy as the current reverses direction.＜/p＞＜p＞Fixed inductors have two primary characteristics: inductance andQ. Inductance is an electrical property of the inductor which measures the amount of resistance to any changes in an electrical current. The inductor\'s Q is a measure of the amount of the energy that is stored in the magnetic field the inductor creates. Generally, higher Q inductors have higher inductances. The higher Q also indicates that the inductor is able to resist changes in current direction. This can be seen in applications such as radio-frequency filters, where a high Q inductor is used to block any signals with frequencies outside the desired range.＜/p＞＜p＞Fixed inductors can be used in a variety of applications, such as filters, amplifier circuits, and power supplies. In filters, the inductor is used to block any undesired high frequency signals and allow the desired frequency signals to pass through. In amplifier circuits, the inductor is usually used to provide a path to a common ground, allowing for a gain increase. In power supplies, the inductor can be used to provide a relatively constant current to the load, allowing for a more efficient use of power.＜/p＞＜p＞Fixed inductors are essential to the operation of any device and they provide a great amount of protection, when they are incorporated properly. These components can resist changes in current direction, block undesired frequencies, and provide a path to ground that will allow for a gain increase in an amplifier circuit. In addition, they can be used in power supplies to provide a relatively constant current to a load, thereby allowing for a more efficient use of power. For these reasons, fixed inductors are an essential component in any electrical or electronic circuit.＜/p＞＜/div＞
