Fixed Inductors are electronic components that store energy in a magnetic field. They are made from coils of insulated wire wound around a core such as ferrite or iron. The current running through the wire generates a magnetic field which stores energy, and the number of turns in the coil affect the inductance of the fixed inductor. The S4924-473H is a type of fixed inductor designed for use in power systems.

The S4924-473H is an axial lead inductor designed for high power applications. It has an inductance of 4.7 mH and is rated for 1000 voltage. The chip is encased in a black resin shell which provides heat dissipation and electromagnetic interference (EMI) protection. The S4924-473H has a high tolerance of ±20% at 100MHz, which makes it suitable for use in power supply circuits where a high degree of accuracy is required. In addition, the inductor has a high saturation current of 22.4A, making it suitable for high amperage applications.

One of the primary applications of the S4924-473H is in filter applications. Filters are used to reduce unwanted electromagnetic interference (EMI) caused by large current surges and abrupt high voltage changes. The inductance of the S4924-473H helps to limit the high frequency current which helps to reduce EMI. The inductor can also be used to provide supply voltage stability in power control circuits and in switching power supplies.

The working principle of the S4924-473H involves the generation of a magnetic field as current passes through the winding of the inductor. The current induces a voltage which is inversely proportional to the rate of change of current. This voltage is known as inductance voltage and is proportional to the inductance of the inductor. This voltage opposes the current and limits its rate of change, thus limiting the amplitude of the output voltage. The number of turns in the winding of the inductor is an important factor in determining the inductance, and is determined by the application.

The S4924-473H is an excellent choice for high power applications due to its high ratings and high tolerance. It is suitable for use in circuits that require supply voltage stability, EMI protection, and high current applications. The working principle of the S4924-473H involves the generation of a magnetic field and an inductive voltage as current passes through the winding of the inductor, making it well-suited for a wide range of applications.
