Fixed InductorsFixed inductors are basically electrical components that store energy in the form of a magnetic field. These components consist of an inductor, a conductor, and a core that can range from ferromagnetic materials, such as iron, to non-magnetic materials such as air. The inductance of a fixed inductor is determined by the size, shape, and type of core.One type of fixed inductor is the SD3814-150-R inductor. This type of inductor is a high-power inductor with a max current rating of 150 amps. It is designed for use in power applications where high efficiency, low temperature rise, and high force magnetic are required. The SD3814-150-R inductor is encased in an aluminum housing which provides a strong and durable construction. It has a radial-lead configuration and is suitable for both surface-mount and through-hole applications.The working principle of a fixed inductor is based on Faraday’s Law of Induction. This law states that a changing current in a conductor will produce a magnetic field, while a changing magnetic field in a conductor will produce a current. Fixed inductors use this phenomenon to store energy in the form of a magnetic field.When a current is applied to a fixed inductor, it creates a magnetic field which in turn creates a voltage across the inductor. The magnitude of the voltage depends on the magnitude of the current, the inductance, and the rate at which the current is changing. This voltage is proportional to the rate of change of the current and is known as the back EMF. The back EMF opposes the applied current and thus keeps the current in the circuit from changing quickly. This characteristic is known as inductive reactance and is used in many circuit applications.The SD3814-150-R fixed inductor is suitable for applications such as DC/DC converters, voltage regulators, switching power supplies, and DC motor control circuits. It provides very low resistance and high strength magnetic which make it ideal for power applications. The radial-lead configuration also provides ease of installation and is able to withstand high temperature and pressure.In conclusion, the SD3814-150-R fixed inductor is a high-power inductor designed for use in power applications. It is based on the principle of Faraday’s law of induction and utilizes a radial-lead configuration for ease of installation. The inductor is suitable for circuits such as DC/DC converters, voltage regulators, switching power supplies, and DC motor control circuits. Thanks to the high efficiency, low temperature rise, and high force magnetic of this inductor, it is a great choice for power applications.
