Fixed InductorsA fixed inductor, also known as an inductor, is a passive electrical device used to store energy in the form of a magnetic field. Fixed inductors are typically made up of a coil of wire, ferro-magnetic core material, or a combination of both. They consist of two terminals, the positive and negative terminals, which connect the inductor to a circuit. The primary application of a fixed inductor is in providing a stable source of a desired amount of electrical current to a circuit.The LQH43NN820K03L is a fixed inductor manufactured by Murata. It is suitable for use in automotive electronics applications, such as in-car navigation systems. It is a surface mount device, with a high reliability, small footprint, and low profile design. It has a suitable DC withstanding voltage of 11V and a rated voltage of 10V, making it suitable for use in automotive applications. It also has a high self-resonant rate of 400MHz making it suitable for use in a wide frequency application range.The working principle of the LQH43NN820K03L fixed inductor is relatively simple. When AC current is applied to the inductor, it creates a magnetic field. This magnetic field interacts with the coil of wire inside the inductor, creating a self-resonant frequency. This self-resonant frequency is proportional to the number of turns in the coil of wire, and is measured in Megahertz (MHz). The higher the frequency, the higher the efficiency of the inductor, and the higher the performance of the circuit.As the AC current passes through the inductor, the magnetic field induces a voltage in the coil of wire. This voltage is then transferred to the terminals of the inductor, which is then passed on to the circuit. The current then flows through the circuit, thus providing a stable current source for the circuit. This process is known as inductive coupling.The LQH43NN820K03L fixed inductor is a high performance surface mount device that can provide a stable source of electrical current to a circuit. It has a high self-resonant frequency of 400MHz, and a DC holding voltage of 11V. It is suitable for use in a wide range of automotive electronics applications, such as in-car navigation systems. The working principle of the fixed inductor is based on the principles of inductive coupling, where a magnetic field is created that induces a voltage in the coil of wire. This voltage is then transferred to the terminals of the inductor, and then passed on to the circuit.
