Introduction to Fixed Inductors

Inductors are electronic components used in a variety of applications to store and release electric energy. They can also be used in power supplies, filters, regulators, oscillators and other applications. They work on the principle of electromagnetic induction, where an electric current flowing through a coil induces a magnetic field, which produces a voltage in the opposite direction of the electric current. The voltage induced is proportional to the rate of change of the electric current, which is determined by the inductor’s design and construction.

Types of Fixed Inductors

Fixed inductors come in many shapes, sizes, and configurations. They are classified according to their structure and properties. Types of fixed inductors include air-core, ferrite-core, toroidal, pu-core, and mica. Air-core inductors rely on a cylindrical coil or a helically wound coil made of metal, usually copper or aluminum. The gap between two sections of the coil is aerated, leaving only air between them. This construction helps them to be relatively low cost and small in size. They generally have a high inductance value.Ferrite-core inductors are also coils that are wrapped around a ferrite core. The ferrite core helps to increase the inductance of the coil at higher frequency and also reduces the amount of power lost on the winding during operation. Toroidal inductors are similar to ferrite-core designs but usually feature a round toroidal shape. This helps to reduce power losses and promote a superior electromagnetic field compared to other designs.Pu-core inductors are a newer technology that uses a special, high-temperature resistive material to create an increased inductance with minimal power loss. They are often used in computer systems, TV sets, cell phones, and other electronic equipment. Mica inductors are also high-frequency components, typically used in RF circuits. They feature a mica dielectric that helps reduce the losses experienced in operation.

Application Fields of the #B953AS-181M=P3 Inductor

The #B953AS-181M=P3 inductor is a fixed inductor featuring a ferrite core and a copper winding. This inductor is rated for a maximum current of 1.1A, a working frequency up to 5.5MHz, and an inductance of 181mH. It is suitable for a variety of applications, including power supplies, switching regulators, audio filters, oscillators, and instrumentation. It is also useful for RF circuits and digital signal processing applications.

Working Principle of the #B953AS-181M=P3 Inductor

The #B953AS-181M=P3 inductor works on the principle of electromagnetic induction. As an electric current passes through the coil of the inductor, it induces a magnetic field. This magnetic field then produces a voltage in the opposite direction of the electric current, which is proportional to the rate of change of the electric current. The inductance of the inductor determines how much voltage is induced for a given rate of change of the electric current.The ferrite core of the #B953AS-181M=P3 helps to increase the inductance of the coil and also reduce the amount of power lost on the winding during operation. The copper winding helps to reduce the resistance of the inductor, resulting in higher efficiency. The multiple windings also helps to increase the circuit’s inductance.

Conclusion

The #B953AS-181M=P3 inductor is a fixed inductor featuring a ferrite core and copper winding. It is suitable for a variety of applications, including power supplies, filtering, audio and RF circuits. It works on the principle of electromagnetic induction, where a magnetic field is induced when an electric current passes through the coil, producing a voltage in the opposite direction of the electric current. The ferrite core helps to increase the inductance and reduce power losses, while the copper winding helps to reduce resistance and improve efficiency.
