What are power inductors?
A power inductor, also known as a coil or a reactor, is a two-terminal passive electronic component used to store energy in the form of magnetic field. Sumida offers a wide range of inductors for a variety of different applications.
What is isat inductor?
Saturation current, denoted as Isat, is defined as the amount of DC current to cause inductance drop. This is typically 5-35 % of its initial value. Since a high saturation current does not drive the component to zero inductance, it becomes an air inductor remaining above zero.
Why are inductors used in power supplies?
In power supplies, an inductor’s role is to prevent sudden changes in current used. Working alongside a capacitor, an inductor prevents sudden changes in the power supply’s output voltage and current. Overall, they’re very simple components that play a critical role in power electronics.
Where are power inductors used?
A power inductor is used in a step-up, step-down, or step-up/step-down circuit to convert a certain voltage to the required voltage. Among those different circuits, it is primarily used in a type of circuit called a “switching regulator.”
How are inductors rated?
There are two methods of determining the rated current of power inductors: “rated current based on self temperature rise,” and “rated current based on the rate of change in inductance value.” Operation in excess of this range may increase the ripple current, causing the IC control to become unstable.
What are the different types of inductors for decoupling?
Depending on the application there are many types of inductors, they come in various form factors, there are high-frequency inductors, low-frequency power line inductors, and some specially designed inductors for decoupling and filter applications, below we will discuss different types of inductors in details.
Are there different types of inductors for different applications?
Types of Inductors Depending on the application there are many types of inductors, they come in various form factors, there are high-frequency inductors, low-frequency power line inductors, and some specially designed inductors for decoupling and filter applications, below we will discuss different types of inductors in details.
What’s the difference between an inductor and a capacitor?
Furthermore, the inductor stores energy in the form of a magnetic field, and the capacitor stores energy in the form of an electric field. In this article, learn more differences between inductor and capacitor.
What’s the difference between a choke and an inductor?
Understanding the difference between chokes and inductors is essential when designing devices and machinery that rely on electrical power. These electrical components each suit specific applications. A choke is a type of inductor, but its application, function, and design differ from other inductor designs.
