Fixed Inductors - B82422T3390K000

Inductors are widely used in electronic circuits. They are usually used as coils to store energy and provide smoothing effects in power supplies, and can be used to increase signal current, provide radio frequency (RF) transformation, and filter signals. Fixed inductors are among the most commonly used kind, and the CoilCraft B82422T3390K000 is an example.

Application Field

The B82422T3390K000 measures 22⁄ 7 x 14⁄ 7 x 7⁄ 5 mm and features a molded construction with tight tolerances for improved performance. It is designed for high-density surface-mount applications such as power supplies, energy storage circuits, switching power supply circuits, coupled circuits, etc. It can also be used in automotive electronics, communication equipment, portable products, display devices, computer peripherals, industrial instrumentation, motor control, etc.

Working Principle

An inductor works by storing energy in the form of a magnetic field as current passes through its windings. The windings of the B82422T3390K000 consist of copper foil covered in an insulation film. This construction provides excellent high-frequency performance, low DC resistance, superior current handling capability, and improved solderability and heat resistance. This makes the B82422T3390K000 ideal for high-density installations.

When current passes through the inductor, a magnetic field is created that induces a voltage to oppose the current flow. This is what is known as inductive reactance. The inductance is the measure of how much this reactance opposes current flow. The B82422T3390K000 has an inductance of 3.9 µH, which indicates that it offers excellent reactance and increases the signal current, making it suitable for power supplies, energy storage, switching power supplies, and other circuit designs.

Conclusion

The CoilCraft B82422T3390K000 is a fixed inductor that can be used in a variety of applications, such as power supplies, energy storage circuits, switching power supplies, coupled circuits, automotive electronics, communication equipment, portable products, displays, industrial instrumentation, and motor control. Its construction features copper foil and an insulation film, which provides excellent high-frequency performance, low DC resistance, superior current handling capability, and improved solderability and heat resistance. It is an ideal choice for high-density surface-mount applications and has an inductance of 3.9 µH.
