Fixed inductors are passive components that are used in electronic circuits for storing electric energy or for the purpose of transforming the voltage, current, or frequency of signals. The 105R-471J is a large-sized surface-mount fixed Inductor designed for use in a range of different electronic applications.

The 105R-471J is a radial-lead, axial-mount inductor with a ferrite core. It has four leads, two on each side, which are connected to the core via a copper wire. The coil has a nominal inductance of 471mH and a Q-factor of 8.2 at 1MHz. The ferrite core has an overall size of 26mm x 11mm, with a total height of 6mm. It also has a temperature rating of -40C to +125C, and a maximum DC current rating of 2.4A.

Application Field

The 105R-471J is suitable for use in a variety of electronic applications, including switch-mode power supplies, motor control systems, and electromagnetic interference suppression. It is well-suited for use in DC/DC converters, power filters, and high-temperature AC/DC converters. Its high-temperature rating allows for operation in high-temperature environments without compromising on performance.

The 105R-471J is also suitable for use in resonant converters, where it can be used to reduce the switching frequency of the converter and reduce EMI levels. The inductor can also be used in high-temperature DC/DC converters, such as those used in solid-state drives. The small size of the core also makes it suitable for use in space-critical applications.

Working Principle

The 105R-471J is a fixed inductor, meaning it does not change its inductance value with the applied current. It works by using Faraday’s law, which states that an induced electromotive force is generated in a conducting wire whenever the magnetic flux linking the wire is changed. In the case of the 105R-471J, an alternating current induces a high voltage, which is passed through the inductor and then through the core of the inductor.

The induced voltage acts on the resistor or capacitor, which functions as the load for the inductor. The current flowing in the inductor causes the core of the inductor to become magnetized, and this reduces the current flowing through the load. This is known as the inductor’s self-resonance, which is the basic principle of operation for the 105R-471J.

The 105R-471J is a rugged and reliable fixed inductor that can be used in a wide range of electronic applications. It provides high inductance with minimal losses and is suitable for use in a large range of DC/DC converters, power filters, and high-temperature AC/DC converters. The inductor has a temperature rating of -40C to +125C, and a maximum DC current rating of 2.4A, making it ideal for use in high-temperature electronics.
