Fixed inductors refer to those inductors whose core parameters, inductance, and self-resonance frequency remain unchanged in the specified frequency range or temperature range, and are usually materials with non-linear or linear properties. 156R fixed inductors are mainly used in high-voltage, low-voltage, power frequency, and other fields to store electric energy and help the circuit\'s signal transmission, improve signal quality, and protect circuit safety. The main application of 156R fixed inductors is radio frequency interference suppression.

It is mainly composed of an air-core inductor, a single-layer or multi-layer winding, an iron core, an outer magnetic shield, and some other parts. The windings of the 156R fixed inductors are usually wrapped with insulation tape to effectively reduce the coupling between different layers of coils. The core is usually made of ferromagnetic materials such as iron powder, iron slag, and amorphous alloy, which can effectively improve the utilization rate of magnetic materials.

The working principle of 156R fixed inductors is based on Faraday\'s Law of Electromagnetic Induction. This law states that when the magnetic flux through a coil changes, the induced electromotive force is generated, which causes the current to flow through the coil. In the 156R fixed inductors, when the voltage is input, the current carries the magnetic flux to the coil, which in turn induces the current to flow, and then the coil will store the energy with the current, which is called inductance.

The traditional 156R fixed inductors mainly use silicon steel cores and air-core coils, and the materials of these components are also rich and diverse. They include ferrite cores, MnZn ferrite cores, NiZn ferrite cores, mu-metal cores, ferrite sheets, iron powder cores, copper powder cores, chip cores, and more. Different cores have different characteristics, and can be used in different applications according to their characteristics. In addition, there are also many different parameters that affect the performance of 156R fixed inductors, such as the core geometry, inductance, frequency, current, voltage, temperature, and more.

In general, 156R fixed inductors are widely used in many applications due to their ability to store energy in a circuit and help improve the signal\'s quality and protect the circuit’s safety. They can be used in RF interference suppression, filter networks, high-voltage, low-voltage, and power frequency applications. Understanding their working principle and properties is necessary to make sure that they can be used safely and effectively.
