Fixed Inductors

B78148E1101M000 is a type of fixed inductor. It is composed of a multiple core, typically laminated, and the windings are commonly insulated with an interlayer insulating material. The magnetically active part of the winding is typically made of a single conductor, surrounded by insulation to protect it from external electrical interference.

Application Field

Fixed inductors are widely used in the fields of electronics, medical instrumentation, automotive, and telecommunications systems. In the field of electronics, they are often used as resonators for a variety of electronic circuits, such as oscillators, filters, and amplifiers. They are also commonly used as signal-processing components for resonant circuits. As powerful components for communication, they are capable of controlling electromagnetic waves and radio frequency signals. In medical instrumentation they are used to receive signals from bioelectric organs, such as the heart or brain. Moreover, they can also be used in automotive applications, such as door opening and closing systems, engine control systems, and audio systems.

Working Principle

The working principle of a fixed inductor relies on the magnetic principle of current flow. When an alternating current is passed through the inductor, a magnetic field is created within the device. This field creates an opposing force to the flow of the current, resulting in the creation of a voltage drop across the inductor. This voltage drop is known as the inductor voltage, or the inductive voltage. This voltage creates an oscillatory current in the inductor, which increases in intensity as the magnitude of the field increases. As the current increases, the magnitude of the magnetic field also increases, thus creating and sustaining an oscillation in the current.

The magnitude of the oscillation is determined by the number of turns of the winding and their cross-sectional area. As the current increases, the field generated by the inductor also increases and eventually saturates. Once the field saturates, the current stays constant, and the inductor voltage changes from its maximum value of the saturation voltage to zero. This is known as the saturation voltage.

Similar to other electronic components, the B78148E1101M000 also offers a wide range of operating performances. As an example, it can deliver a maximum current of 0.35A, and a minimum inductance of 32mH. The quality factor is also very important, as it indicates how efficiently the inductor dissipates the energy that is stored in the magnetic field. With a quality factor of 25.5, this device is highly reliable and ensures long-term operation.
