Fixed Inductors

744052101 Application Field and Working Principle

Fixed inductors, also known as base-mounted coils, are wound inserts that are typically used within any electric circuit for the purpose of signal filtering, signal smoothing, current sensing and voltage transformation. The 744052101 inductor is available in two different sizes and has an inductance of 47uH with a tolerance of 5%. It is compounded of one nucleate MI ferrite core and two windings covered by a resin, the latter allowing the inductor easier maintenance.

Due to the 744052101 being a fixed inductor, there are several different principles and applications for these inductors. They are primarily used in DC break circuits for the purpose of filtering any undesirable ripple and oscillations that could be produced by any power source. To achieve this, the inductor varies its AC impedance while limiting the frequency of any ripple. Additionally, the inductor is used as a transformer in order to step up or step down the voltage of the incoming voltage. Since the applied voltage will typically be AC, the thicker turn of the transformer will generate a higher voltage, while the thinner turn generates a lower voltage.

As a result of its dual-winding capabilities, the inductor is also used in motor control systems, such as PID controllers and motor drives. This allows the inductor to receive the power that is necessary to keep the system functioning and regulates the power input. In many cases, the inductor can be designed to either increase or decrease the flux density of the motor depending on the speed requirements that is needed. In this way, the inductor can be used to regulate the speed of the motor.

Furthermore, inductors are used as a current sensor in measurement applications. To do this, the inductor is inserted in the circuit such that any current changes in the external circuit can be measured as a result of any changes in the inductor’s generated magnetic field. This same principle is also used in the detection of any short circuits or ground faults.

The 744052101 inductor is a powerful tool that can be used within a variety of applications, due to its versatility and durability. It is available in different sizes and inductance values which allows it to be used in a vast range of electric circuits. With its high level of performance and accuracy, this inductor is suitable for a wide variety of uses.
