It’s compact size enables it to be used in a variety of power supplies, making it ideal for aerospace, automotive, industrial and consumer applications. Additionally, it offers protection from common mode noise, which can be caused by ground loops or other disturbances.

Working Principle

The 3090-181F Inductor works by using electromagnetic induction to store energy in the form of a magnetic field. As electric current passes through the inductor, a magnetic field is produced in and around the component. This magnetic field resists changes to the current, and as a result, it “induces” a voltage into the inductor in the opposite direction of the current. This voltage resists the passage of the current, thus creating inductance in the circuit.

As the current continues to flow, the magnetic field increases and the induced voltage increases with it, until the magnetic field reaches saturation and cannot be increased any further. At this point, the energy stored in the magnetic field is released back into the circuit, and the inductance becomes zero.

Inductors are strictly linear components, meaning that they will always be affected by the same Ohm’s Law (V = IR) that applies to resistors and capacitors. This principle allows inductors to be used in a variety of applications, from power supplies to filters, oscillators, and signal integrity components.

Conclusion

The 3090-181F Inductor is a small, surface-mountable device primarily used in switching power supplies. With its wide operating temperature range and excellent heat exchange, it’s suitable for a variety of industrial and consumer applications. Additionally, its inductive properties make it an ideal choice for protecting against common mode noise and for storing energy in the form of a magnetic field.
