Fixed Inductors

Inductors are electrical components that store energy in a magnetic field and, when correctly designed, can provide inductance in a given circuit. Fixed inductors are designed for a fixed inductance value, often described in H, that cannot be changed. The 108R-393J inductor is a fixed component that is typically used in DC-DC converters, audio amplifiers, radio and telecommunications equipment, and many other applications.

Application Field

The 108R-393J fixed inductors have a wide range of applications in both consumer and industrial electronics. Some of the most common uses include DC-DC converters, audio amplifiers, radio and telecommunications equipment, computer peripheral circuits, switching power supplies, and motor drives. These inductors are ideal for applications such as flyback converters, synchronous and diode-capacitor rectifiers, boost capacitors, and better power factor converters.

The 108R-393J have a very low operating temperature and exceptional thermal and mechanical stability, making them extremely reliable and suitable for use in most power applications. The inductors can also operate over a very wide temperature range and provide a high degree of power efficiency. They are also designed to meet the requirements for low audible noise in order to prevent the effects of switching noise on audio signals.

Working Principle

The 108R-393J fixed inductors work based on a simple principle. When a current is passed through the coils of the inductor, the relative motion between the magnetic field and the coil induces a voltage in the coil. This voltage is called “back-EMF” or “self-inductance”. The more coils or turns of copper wire around the core, the higher the inductance becomes. The inductance of the 108R-393J inductor is fixed and cannot be changed.

The inductance of the 108R-393J fixed inductors is controlled at the design stage by changing the number of turns on the coil accordingly. This number is determined according to the design requirements and is then printed onto the enclosure of the inductor. Due to the fixed inductance value of the 108R-393J, it is important to select inductors that meet the specific inductance requirements of the project.

The 108R-393J fixed inductors are a great choice for a wide variety of electronic components. Despite their fixed inductance value, they are capable of providing reliable performance and a high degree of power efficiency. The low operating temperature and exceptional thermal and mechanical stability make them a great choice for many different applications. With the right selection process, these inductors can easily meet any project’s specific requirements.
