Fixed Inductors are a type of electrical component that can be used in a variety of applications. The ELC-12D332E is one such fixed inductor, commonly seen in aerospace, military and medical applications. In this article, we will take a look at the ELC-12D332E\'s application field and working principle.

The ELC-12D332E is an inductor with a nominal inductance of 1.50µH and a rated current of 2.8A. It is a surface-mountable package with a maximum casing size of 12.5 mm x 7.0 mm x 6.8 mm. This makes it well-suited for applications that require a smaller form factor such as in mobile phones and other portable electronics.

The ELC-12D332E can be used in a variety of applications, such as in high frequency switching power supplies, RF power amplifiers, local oscillator circuits, clock circuits, and other applications requiring a high frequency inductor. Its primary usage is to reduce the electromagnetic interference caused by high-frequency current switching to other electronic devices.

When the ELC-12D332E is used in a circuit, the circulating current level within the Coil Inductor is determined by the total equivalent inductance (impedance) of the system. The total equivalent impedance is the sum of the self-inductance of the inductor and the external circuit inductance. At low frequencies, the inductor’s circuit inductance dominates and at higher frequencies the self-inductance begins to dominate. This is the principle behind the ELC-12D332E’s performance.

The total inductance of the system is also affected by frequency, temperature, winding geometry, and core material. For example, the temperature coefficient of an inductor describes the rate of change of its inductance with temperature. As temperature increases, the inductance decreases. This means that it is important to consider the temperature variation in the system when selecting an appropriate inductor for a given application.

In summary, the ELC-12D332E is a fixed inductor designed to reduce the electromagnetic interference caused by high-frequency current switching. Its application field is wide and ranges from high frequency switching power supplies to local oscillator circuits. Its working principle is based on the total equivalent inductance of the system, which is affected by the frequency, temperature, winding geometry, and core material. The ELC-12D332E’s compact size makes it suitable for use in mobile phones and other portable electronics.
