160R-473HS

Fixed Inductors

A fixed inductor is an electronic component that stores energy in its electric field. It is typically a coil of wire, sometimes referred to as a choke, wound around a core made of ferrite, ceramic, or any other magnetic material. When a current passes through it, the inductor will store energy as an electromagnetic field for a short period of time.

The 160R-473HS is an example of a fixed inductor, specifically, a heavy-duty molded toroidal inductor.It is capable of providing energy storage up to 10,000 uH and can withstand an operating temperature of up to 135 °C. It is specifically designed for applications that require high efficiency, high ripple current or high rated current, such as power supplies, motor drives, RF amplifiers, and laptop chargers.

The working principle of a fixed inductor is based on Faraday’s Law of induction. This states that the magnitude of induced emf (electromotive force) in a circuit is equal to the rate of change of the magnetic flux it encloses. In other words, the more quickly the magnetic flux through the inductor changes, the greater the induced emf will be. This emf is what builds the electromagnetic field within the inductor.

When a current passes through the inductor, it creates a magnetic field. This, in turn, produces an electric field and thus a “back EMF” which opposes the input current. The amount of this opposition is directly related to the properties of the inductor, such as its size, shape, and the number of turns in its coil. This opposition is known as inductance, and the value of inductance is measured in henries (H). The larger the value of inductance, the greater the opposition, or shared, to the input current flow, and thus the greater the energy stored in the inductor.

When the input current ceases, the stored energy releases back through the inductor, allowing the current to continue flowing. This is known as inductive reactance, and it is expressed in ohms (Ω) and measured in amperes (A). The lower the value of inductive reactance, the more easily the energy is released. The 160R-473HS, for example, has an inductive reactance of 0.16Ω for a given frequency.

In summary, a fixed inductor such as the 160R-473HS is an electronic component that stores energy in its electric field. It works by utilizing Faraday’s Law Of Induction to induce an electromotive force which builds an electromagnetic field within the inductor. As a result, when a current passes through it, energy is stored in the inductor, and when the current ceases, energy is released back. The 160R-473HS is designed specifically for high-efficiency applications such as power supplies, motor drives, RF amplifiers, and laptop chargers.
