Fixed inductors, also known as inductors, are components that store energy in the form of an electromagnetic field due to the "self-induction" principle. While being one of the earliest and most commonly used electronic components, fixed inductors are still widely applied in circuits that require inductors, like radio receivers, communication devices, and power electronics. This article aims to provide an overview of the specific application field and working principle of the fixed inductor SDR0302-560KL.

The SDR0302-560KL is a type of fixed inductor commonly used in electronic circuits for the purpose of filtering out unwanted frequencies. Generally speaking, a filter circuit is made up of multiple capacitors and inductors. While capacitors are used to eliminate low-frequency noise, inductors are used to eliminate high-frequency noise. In other words, fixed inductors are designed to restrict the flow of high-frequency electrical signals.

Fixed inductors are usually fitted with a coil, comprising of enameled copper wire around a ferrite core or, in some cases, an air core. The ferrite core or air core acts as the medium for electromagnetic induction. An alternative are ferrite beads, which contain a single layer of permeable ferrite material and are mainly used to shield against electromagnetic interference (EMI).

In terms of power electronics applications, the SDR0302-560KL is especially suitable for efficient power conversion due to its low resistance at higher frequencies. Fixed inductors also have the ability to block low frequencies and allow high frequencies to pass, which makes it an ideal choice for power converters that require high-frequency switching. Furthermore, inductors are used in buck, buck-boost, and isolated boost switching converters, as well as frequency inverters, and any other circuit that relies on the use of energy storage.

The SDR0302-560KL is made of a differential-mode inductor that features low self-inductance, low losses, and non-interference. Its construction includes: a soft magnetic core, like a ferrite core, which is used as the medium for electromagnetic induction; and an enamel coated copper wire of suitable thickness wound on the core. The combination of the core and wire creates an inductive component that can be used in a variety of power supply designs. The SDR0302-560KL is built for split-core inductor applications, which require very low levels of ripple current, as well as high-speed switching.

To sum up, the SDR0302-560KL is a type of fixed inductor used in a variety of applications, such as power electronics, radio receivers, and communication devices. Its construction includes a soft magnetic core along with an enamel coated copper wire wound around it, providing a low self-inductance, low losses, and no interference. The SDR0302-560KL is mainly used for filtering high-frequency noise and energy storage, and it’s capable of blocking low frequencies and allowing high frequencies to pass.
