Fixed Inductors

Fixed Inductors are solenoid windings comprising of a single or multiple loops of conductive wire placed on a core used for storing energy. A common type of fixed inductor used is 9230-74-RC. This article will discuss the applications for this type of inductor and the working principle behind it.

Applications

The 9230-74-RC Fixed Inductor is typically used in applications which require a current limiting feature, as the inductor stores energy and opposition to changes in current. It is also used in voltage regulation within power supplies, frequency determination, an impedance matching device for signal circuits, and for filtering. This type of inductor is also used within resonance circuits to determine the resonant frequency.

Working Principle

A 9230-74-RC Fixed Inductor works by creating a resistor-capacitor (RC) circuit. This is achieved by including a resistor and a capacitance in conjunction with the inductance of the winding. In essence, the inductor slows down the rate of change of current flowing within the circuit, which can cause voltage drops as the winding is essentially acting as a battery. This is a resistance-readingeffect which allows the current to be regulated, thereby limiting current flow and increasing the power efficiency of the circuit.

The inductor is also used as an impedance matching device in signal circuits, as it is capable of transforming impedance levels for optimum connection. This is another example of an AC current-limiting effect, as energetic signal wave patterns are transformed into smoother signals.

Conclusion

The 9230-74-RC Fixed Inductor is a versatile device which can be used as a current and voltage regulator, frequency determiner, impedance matching device, and filter. Its working principle involves creating an RC circuit to resist changes in current, allowing current and voltage levels to be regulated for improved power efficiency.
