Fixed inductors, otherwise known as non-variable inductors, play a key role in electrical circuits as the current passing through them is restricted. One such type of fixed inductor is the PL9213NLT. This article will provide an overview of the application field, associated usage and the working principle of the PL9213NLT, and how it fits into the fixed inductor category.

The PL9213NLT is typically used in AC/DC circuit applications and is designed for an operating frequency range of between 100kHz and 600kHz. It is constructed from a small ferrite core with multiple turns of wire, and provides a notable impedance of 0.39Ω at high frequencies.

This inductor can be used with a variety of components, but is particularly suitable in power supplies and switching circuits for the control of voltage spikes, current over-shooting and ringing peaks. It is notable for its high self-resonance frequency, which can be as high as 1,500kHz if required by the component.

Due to its construction, the PL9213NLT has excellent temperature characteristics with low drift and low DC resistance. It also has a small physical size which allows for stable, long-term use in cramped electronic circuit applications. In addition, the light weight of the component means it can be easily combined with a range of weight-sensitive connector designs.

In terms of the working principle of the PL9213NLT, it follows a relatively simple design as the core is made up of multiple turns of wire wound around a small ferrite body. The windings work in conjunction with an external capacitor which creates an internal short circuit and this is used to obtain the required inductance.

When a current flows through the winding, it creates a magnetic field which in turn produces an electric current across the inductor. This creates a differential in the voltage which then produces a force which opposes the change in current. This property is known as inductance and is essential for controlling current in AC/DC circuits.

In conclusion, the PL9213NLT is a type of fixed inductor that is used in AC/DC circuits, and is particularly useful in the control of current over-shooting, voltage spikes and ringing peaks. It is notable for its high self-resonance frequency, excellent temperature characteristics and small physical size, and its working principle is based on the interaction between multiple turns of wire and external components. Therefore, the PL9213NLT is a valuable asset in the development of modern electrical circuits, making it a key component in the fixed inductor category.
