Fixed inductors refer to various types of inductors that do not have adjustable parameters. Most fixed inductors are formed by winding insulated copper wires around a ferrite or other core. The most common type of fixed inductor is the AIRD-02-2R7M. This article will discuss the application field and working principle of the AIRD-02-2R7M.

Application

The AIRD-02-2R7M is a multi-layer fixed inductor designed for use in power conversion circuits such as switch-mode power supplies (SMPS) and phase-shift full-bridge circuits. It is suitable for use in a wide range of input, output, and bias currents typically encountered in DC-to-DC converters and similar applications. The inductor has a low DC resistance that reduces power losses and a high operating temperature that allows for greater power output and higher reliability. Additionally, its high saturation current allows for a wide range of switching frequencies.

Working Principle

The working principle of the AIRD-02-2R7M is based on electromagnetic induction. When the inductor is connected to an AC power source, a current will flow through it. This induces a magnetic flux in the core of the inductor, which will induce a voltage in the windings. This voltage opposes the current, which reduces the rate of change of the current. This increase in reactance reduces the overall current flow through the inductor, allowing for greater power efficiency.

In addition to reducing the current flow, the AIRD-02-2R7M also has two other key features that make it an excellent choice for a wide range of applications. Firstly, the inductor has a self-healing feature that allows it to recover from a short circuit caused by external forces. Secondly, the inductor can support up to 1.8MHz of operating frequency, making it ideal for high-speed switching applications.

Conclusion

The AIRD-02-2R7M is an excellent choice for applications requiring a high-performance, fixed inductor. Its low DC resistance and high operating temperature make it ideal for DC-to-DC converters and other power conversion circuits. In addition, the inductor has a self-healing feature and supports up to 1.8MHz of operating frequency. All these features make the AIRD-02-2R7M a great choice for a variety of applications.
