ELJ-FB470JF Inductors, Coils, Chokes

Fixed inductors are components used in electronics and electrical power systems to store and release electrical energy in a circuit. The ELJ-FB470JF inductor is a type of fixed inductor which can store energy at low frequencies. It is widely used in radio frequency (RF) and microwave circuits, as well as motor and power management applications.

The ELJ-FB470JF is a surface-mounted, cylindrical inductor with a small form factor. It is relatively compact, with only 5.2mm height, 2.6mm diameter and a weight of just 0.3g, making it an ideal choice for applications where space is a limiting factor. The inductor is made of ferrite material and is encased with a protective plastic housing.

The working principle of the ELJ-FB470JF is based on the principle of Faraday’s Law, which states that a time-varying magnetic field produces an electromotive force (EMF) in a nearby conductor. This EMF produces a current in the conductive coil, which in turn creates an opposing magnetic field. This opposing field reduces the original field, causing current to flow around the coil, thus creating inductance. By controlling the amount of current, the inductors can store and release electrical energy in a circuit.

The ELJ-FB470JF offers a high Q-factor, low DC resistance, and high inductance. It is available in a wide range of values from 0.2µH to 2.7µH, enabling its use in various high-frequency power management and RF applications. Its application fields include switching power supplies, power management circuits, and radio and high-frequency telecommunications technologies. The ELJ-FB470JF is ideal for applications wherein high energy storage and noise-free operation is required in a small form factor.

The ELJ-FB470JF is a cost-effective and reliable fixed inductor that can provide significant benefits in power and monitor applications. Its compact size and high performance make it a great choice for space-limited applications, as well as high-frequency circuit designs. It is suitable for use in small form factor low-profile applications as well as portable devices.
