Fixed InductorsInductors, also known as coils, coils, chokes, or reactors, are one of the most basic and widely used electrical components. A fixed inductor, or passive inductor, is an inductor whose inductance value is fixed. The most commonly used fixed inductors are 1812R-333H. In this article we will take a look at the application field and working principle of 1812R-333H.1812R-333H fixed inductors are typically suitable for applications in DC/DC converters, DC power line filters, EMI noise suppression, and other power line applications. These inductors serve as an ideal energy storage device which helps reduce voltage spikes and improves the overall operation of a circuit. They are also used as RF shielding and power line protection.The 1812R-333H fixed inductor is composed of a coil wound around a ferrite core. The coil is made of copper wire and the core is made of ferrite with high leukocyte. The number of coils and the thickness of the copper wire are selected according to the required inductance. The internal structure of the 1812R-333H is designed to provide excellent noise reduction and improved power conservation, making it an ideal choice for many applications.The working principle of 1812R-333H is based on Faraday’s law of induction. When a varying current flows through the coils of a fixed inductor, a varying magnetic field is created, which causes a voltage to appear at the terminals of the inductor. The level of induced voltage depends on the rate of change of current through the coils. This process is known as inductive reactance and is represented by a complex frequency-dependent impedance.In conclusion, the 1812R-333H fixed inductor is a widely used device for applications such as DC/DC converters, DC power line filters, EMI noise suppression, and other power line applications. It works by creating a varying magnetic field which induces a voltage at its terminals. The induced voltage is dependent on the rate of change of current through the coils and is represented by a complex frequency-dependent impedance.
