Fixed inductors are one of the basic passive electronic components in contemporary electronic circuits, which are mostly used to pay the inductance value required by various circuits.Their application field and working principle are different according to their types. Let\'s take the commonly seen PL1525T series inductors for example to introduce their application field and workings.

The PL1525T series inductors are characterized by a wide range of inductance values of 1uH to 10mH, and a relatively high temperature coefficient.Their main applications are power supplies, automotive electronics, audio amplifiers, computers, telecom and other environments.

The working principle of the PL1525T series inductors is based on the principle of Faraday\'s law of induction which governs transformer operation. This law states that an electric current creates a magnetic field, and a changing magnetic field implments an electric current. Hence, a coil of wire having many turns creates a greater magnetic field. The same principle works when constructing a transformer of inductors, when a current of one inductor transfers energy to another inductor via their magnetic fields.

The specific structure of PL1525T is a bobbin wound around a ferrite core, and each winding contains a separate portion of wire that can be connected to the outside of the core. Then, when a voltage is applied across the two ends of the wire, the iron core in the center will magnetize, thus creating a magnetic field with the same polarity as the core. As the current passes through the winding, a magnetic field is generated, and this will induce a reverse EMF in the winding, causing a voltage of opposite polarity to be applied to the end of the wire. As a result of this, the sum total of voltage across the whole winding is increased.

The application of the PL1525T series inductors is widespread across the industrial and electronics world, because of its superior functionality and wide inductance range. In addition to their use in power supplies, they are used in a variety of audio and automotive electronics products as well. They are also used for filtering and coupling in radio frequency systems, and in voltage regulators and power converters. In short, inductors are used in any circuit where it is necessary to direct, or alleviate, current flow.

In conclusion, the PL1525T series inductors are one form of fixed inductors that can be widely used across many electrical and industrial fields due to its superior performance. Its working principle is based on Faraday\'s law of induction which governs transformer operation. Its specific structure is a bobbin wound around a ferrite core, and the magnitude of the voltage across each of the winding determines the induced current. As a result, the PL1525T series is an ideal passive electronic component to add value to various electronic devices.
