Fixed InductorsInductors are passive components that create a magnetic field when a current passes through them. They are used in electricity, electronics and telecommunication circuits to store energy and control current flow. The S0402-4N7J1 fixed inductor is a surface mounted device specifically designed for use in circuit boards that require precision applications.

S0402-4N7J1 ApplicationThe S0402-4N7J1 is a surface mount, low profile inductor designed for high frequency applications such as PLL circuits, power supplies, power converters, and other high speed circuits. It is made from high quality metal which allows it to have excellent inductance, high operating frequency and low DC resistance. The inductor is capable of working with currents up to 100mA and frequencies up to 6.5GHz.

S0402-4N7J1 Working PrincipleThe S0402-4N7J1 fixed inductor works on the principle of electromagnetic induction. This is when a changing current flows in a conductor, it creates a magnetic field that induces a voltage in another part of the circuit. When a current passes through the inductor, a magnetic field forms around the wires which store energy. The energy is then released in the form of a current.The current in the inductor is proportional to the rate of change of the flux in the core. As the current passes through the inductor, the magnetic flux in the core increases at a certain rate until the core is completely saturated and no more flux can be induced. The peak point of the flux is the inductance of the inductor.

ConclusionThe S0402-4N7J1 is a surface mount fixed inductor designed for precision applications with currents up to 100mA and frequencies up to 6.5GHz. It works on the principle of electromagnetic induction, where a changing current induces a voltage in another part of the circuit. The current in the inductor is proportional to the rate of change of the flux in the core, and the peak point of the flux is the inductance of the inductor.
