SCRH105A-471

Fixed Inductors

The SCRH105A-471 is a fixed inductor that can be used in a multitude of electronic applications. This component serves as an electrical component which offers resistance against current flow in circuits. It can also act as a filter to block high frequencies and reduce the risk of potential noise interference in electronics.

Application Field

The SCRH105A-471 is primarily used to prevent interference from high frequency signals in circuits. This type of inductance component assists in regulating current and can serve as impedance-like limiters within a circuit. Furthermore, it is also ideal for controlling the voltage levels within a circuit.

This inductor is used in part in hyperfrequency applications such as radio-frequency transmission systems, RF communication systems, RF microwave oscillators, power supply systems, electrical signal switching circuits and in matching applications. It is also suitable for use in PCs, mobile phones, automotive electronics, flat-panel TV systems, digital media players, communication systems, medical equipment and power adapters.

Working Principles

The fixed inductor’s core takes the form of a coil made up of ferromagnetic materials such as iron, silicon steel alloys or magnetic powder particles. Through flux, the core material generates a magnetic field which affects the inductance and Q value. The SCRH105A-471 operation is based on electromagnetic induction.

A rectangular element with direct current (DC) is connected to the input side. Magnetic flux is generated by the DC and is then induced onto the input side of the inductance element. This magnetic flux is then linked to its corresponding output side, thereby producing a transmission reaction. The transformer-type action of this electromagnetic induction means that the current and voltage ratio of the input and output sides are always equal.

The Q value of a fixed inductor is determined by the amount of resistance the coil offers against alternating current. In addition to this, the inductance value of the part also affects the Q value. This parameter represents the current change ratio when a certain voltage is applied to a fixed inductor. The SCRH105A-471 is rated at a Q rate of 50, ensuring optimum performance.
