Fixed inductors are electrical components widely used in a variety of circuits, from complex power grids to basic electrical circuitry. ELJ-FA220KF is one particular variant that has specific characteristics that make it preferable in numerous applications.
ELJ-FA220KF, a fixed inductor that is part of the FA series of inductors from Panasonic Electric Works is a surface mount device type and a general purpose fixed inductor whose inductance value is rated at 220 mH + 20%. It has a rated current range of 139.3mA for a resistance value of 0.334 ohms, and a rated voltage of 2.2 Vrms. It can handle up to 15 W and falls under the category of an Axial Leaded Fixed Inductor. As part of the FA series of inductors it offers small size, a wide inductance range, and low DC resistance making it ideal for not only general purpose and power management applications, but also cost sensitive, space-constrained applications such as computer motherboard designs.
The functioning of this fixed inductor is quite simple. It is made of copper which comprises an inductor core and an inductor coil. When a current of certain frequency flows through the copper core, the electrons in the inductor coil get activated and pass through the core, creating a magnetic field. The inductor collects and stores energy in this magnetic field induced in the inductor core. When the current flow is stopped, the stored energy is discharged and helps in providing the circuit with a reversed current.
The primary applications for this type of fixed inductor are in motor control, voltage regulation, power transformers, and small power supplies with a voltage rating up to 15 W. Its compact size helps in providing the circuit board with elegance and easy design. This particular type of inductor is also used in cellular phones, wireless LANs, radio frequency circuit designs, and other similar applications. It is also preferred when dealing with motors, as the inductor helps in providing the precise voltage adjustment and power management. As a result, no other components are needed to build efficient motor control systems.
In conclusion, ELJ-FA220KF fixed inductor is a general-purpose device that is mostly used in power management and motor control applications. It is ideal for cost-sensitive, space-constrained applications and has a wide range of inductance values, a low DC resistance, and a high-current rating of up to 15 W. This type of inductor is one of the most common fixed inductors in the market today and is preferred for a variety of purposes.
