3090R-220K

Fixed Inductors are a fundamental element of electrical circuits. The 3090R-220K is a type of fixed inductor that commonly finds applications in the power electronics and aerospace industries. This article will discuss the application field and working principles of the 3090R-220K fixed inductor and explain how it can be used to great effect in various applications.

The 3090R-220K fixed inductor is most commonly used in continuous-mode fly-back converters. In fly-back converters, the inductor acts as an energy storage device, providing the necessary energy for output voltage conversion. The 3090R-220K inductor has a particularly high current carrying capacity, which makes it well suited for power levels of up to 3kW. In addition to fly-back converters, the 3090R-220K is also used in applications where inductance values at the lower power levels are required. This includes half-bridge, forward, Zeta-type and step-down converters.

The 3090R-220K inductor works in such applications by forming a loop of current, either passing through or near it. This loop is generally referred to as an "induction" loop, as it allows the inductor to "induce" (or create) a magnetic field. This magnetic field stores electrical energy and can then be used to regulate the flow of current. In this way, the inductor acts as a filter, allowing certain frequencies of currents to pass through, while blocking out others.

The 3090R-220K also has the ability to self regulate its inductance level. This is accomplished through the use of copper windings, which react to changing conditions such as temperature and output current. By increasing or decreasing the number of windings, the inductance level can be altered to better suit the application. This self-regulation of inductance can be very useful in applications where the output current needs to be regulated over a wide range of conditions.

The 3090R-220K fixed inductor is also commonly used in aerospace applications. As the name implies, these inductors are used in aircraft, spacecraft, and satellites, where their high current carrying capacity and ability to self-regulate make them ideal for providing power in complex and changing environments. The stable inductance levels achieved by using copper wound components also make them a good choice for applications that require minimal fluctuations in output current over time.

In summary, the 3090R-220K fixed inductor is a versatile and reliable component that finds applications in a variety of industries. Its ability to self-regulate inductance levels, provide high current carrying capacity, and remain stable over a range of conditions make it an attractive choice for use in power electronics and aerospace applications. By understanding the application fields and working principles of this inductor, engineers can make informed decisions on where and how best to use the 3090R-220K in their applications.
