ELJ-NDR12KF

Fixed Inductors are used in a multitude of applications, from frequency filters to power line filtering. The ELJ-NDR12KF is a fixed inductor produced by Murata Electronics, which is a reliable product used in many of these applications. In this article, we will discuss the application field and working principle of the ELJ-NDR12KF.

The ELJ-NDR12KF fixed inductor typically operates between 18 kHz and 52 kHz. It is a toroidal-type or donut-shaped inductor with a rated current of 12 A and an inductance of 10µH. It is constructed with a 30-39µm thicker copper wire bar wrapped around its core. This type of construction helps reduce EMI and radio interference. The ELJ-NDR12KF inductor is a Class B component, so it can only be operated up to the stated frequency range.

The ELJ-NDR12KF fixed inductor can be used in power line filtering applications, such as controlling noise from the power line. It works by preventing higher-frequency signals from entering the application and can be used with other components, such as capacitors, in signal filtering circuits. It can also be used in frequency filters to provide frequencies that could otherwise not be obtained in applications.

The working principle of the ELJ-NDR12KF fixed inductor can be explained using a simplified electrical circuit. In the circuit, current flows into the inductor and is stored in the magnetic field created by the copper wire bar. This is called the inductor\'s inductance. As the current flows, the magnetic field collapses and creates an opposing voltage in the circuit, which is referred to as an inductive reactance. This component therefore works by generating an inductance that limits the current in the circuit.

The ELJ-NDR12KF Fixed Inductor can also be used in other applications, such as motor control systems and transformer mounting systems. This is because it helps to reduce the chance of error and interference from external sources, such as power lines. The ELJ-NDR12KF also provides an excellent current-limiting resistance, which helps to increase the efficiency and safety of the application.

The ELJ-NDR12KF is a great choice for a variety of applications and should be considered when choosing an inductor. Its high efficiency, low noise interference, and cost-effectiveness make it an attractive option for a variety of applications. By understanding its application field and working principle, users can choose the best option for their application.
