Introduction to Fixed InductorsFixed inductors are a type of electrical component that can be used to store and release electrical energy. They are typically found in circuits as part of a larger device circuit board, and are also used in a variety of other applications. Fixed inductors use electrical conductors to create a magnetic field, which stores and releases energy when the current flows through it.RLB1112V4-472J Fixed Inductor Application Field and Working PrincipleThe RLB1112V4-472J fixed inductor is a low profile, high current inductors designed for general purpose applications. It is suitable for use in current filters, temporally tuned circuits, switching power supplies, voltage regulators, power converters, automotive, cell phones, and other high-efficiency applications. This fixed inductor is constructed from a ferrite-bead core with a copper winding, and uses E-Shield technology, which helps to reduce EMI effects. The inductance value of the RLB1112V4-472J is 4.7μH and its peak current rating is 8.5A.The operating principle of the RLB1112V4-472J fixed inductor is quite simple. When a voltage is applied to its terminals, a current begins to flow through the inductor. This current induces a magnetic field in the core, and this field creates a voltage across the inductor. The voltage is proportional to the rate of change of the current flowing through it. When the current increases, the induced voltage opposing the source voltage increases in magnitude, and at some point, the induced voltage exactly cancels the source voltage, resulting in the current not increasing beyond a certain value known as the saturation current. At this point, the current has reached its maximum, and the inductor is said to be in a state of magnetic saturation. As the current decreases, the induced voltage continues to oppose the source voltage, and the inductor returns to its unsaturated state. ConclusionThe RLB1112V4-472J fixed inductor is a versatile inductor designed for use in current filters, temporally tuned circuits, switching power supplies, voltage regulators, power converters, automotive, cell phones, and other high-efficiency applications. The inductor works by creating a magnetic field and inducing a voltage that opposes the source voltage, ultimately preventing the current from increasing beyond a certain point. This makes the RLB1112V4-472J fixed inductor a great choice for any project requiring an inductor with high current capacity.
