Fixed Inductors: 160R-123GS Application Field and Working Principle

Fixed inductors, as the name implies, are electrical components based on inductance (resistance to changes in current), typically used in power supplies and other applications for purposes such as filtering, controlling signal flow, and providing automatic voltage regulation. The 160R-123GS fixed inductor type is an especially important component in this category, and here we look at the various fields it is most applicable in, as well as the underlying electro-mechanical principles which make it work.

160R-123GS Application Fields

The 160R-123GS induction type in particular is often chosen as the best option due to its combination of superior performance characteristics, reliability, and relatively low cost. As a frequency-independent inductor, it is especially useful in the AC power circuits of home electronics, such as video players, DVD players, set-top boxes, digital audio-visual switching equipment, and STB receivers. It is also good for high frequency switching devices, such as amplifiers, power converters, and inverters.

Working Principle

The working principle behind the 160R-123GS fixed inductor can be explained in terms of an inductor/capacitor resonance network; a type of resonant circuit. An idealised equivalent electrical circuit consists of an inductor, L, in series with a capacitor, C, which feed a load impedance, R. The total series of elements creates an oscillating circuit between the inductor, capacitor and the load impedance. This oscillation results in a resonance frequency, represented by the angular frequency, ω = 1/√(LC). At this resonance frequency, the current in the circuit is dominated by the inductor and the voltage is largely determined by the capacitor. In a practical circuit the frequency of resonance may be different due to the effects of load resistance, as well as the electrical and mechanical properties of the inductor and capacitor themselves. In addition, at higher frequencies parasitic elements can come into play, such as the equivalent series resistance (ESR) of the components, which will reduce the current flowing through the inductor and shift the resonant frequency.

Resonance Network Operation in the 160R-123GS Fixed Inductor

The 160R-123GS fixed inductor is designed to function as part of a resonance network, and technical specifications can be found in its datasheet. It is designed as two separated transmission line inductors, with each line composed of four coils and connected to each other by coaxial cables. The first two coils are of the same size and the other two are slightly smaller, creating an artificial resonance node. At the resonance frequency, the inductor is subject to significant cancellation of the losses it experiences, while also generating a high amount of inductance.The design of the160R-123GS fixed inductor helps to ensure that it will resonate and react efficiently in a certain frequency range, depending on the capacitors used in the circuit. This is especially useful in areas where the resonance frequency may be subject to variations, such as in switching power supplies. As an example, a power supply using a resonance network will have the resonance frequency shifted away from its ideal value when the load is increased in order to supply more power. The 160R-123GS fixed inductor provides an effective resonance frequency shift, allowing the power supply to react quickly and efficiently without any significant distortion or loss of power.

Conclusion

In summary, the 160R-123GS fixed inductor type is an important component in the world of electrical and electronic components. It is especially useful in AC power circuits, high frequency switching devices, and switching power supplies. Its operation is based on an inductor/capacitor resonance network, which helps it to react efficiently to a range of variables in the resonant frequency. By combining reliability, low cost, and superior performance, it is the go-to option for many applications.
