ELL-SFG331MA Inductors, Coils, Chokes

The ELL-SFG331MA belongs to a class of fixed inductors. These components are common components used in electronic circuits for a range of different purposes. As the name implies, a fixed inductor has a fixed inductance value, meaning it cannot be varied as the current in the circuit changes. Fixed inductors are used when the circuit requires a specific inductance to filter out certain frequencies or to form a voltage regulating or rectifying circuit.

Application Field

The ELL-SFG331MA fixed inductor is a general purpose inductor with a wide range of applications. It is used for a wide variety of consumer electronics, including audio systems, mixers, power supplies, cellular phones, computer peripherals, and automotive applications. It is suitable for DC-DC converters, high-frequency switching circuits, various power supplies, and various inductive circuits. Additionally, the ELL-SFG331MA is used in radio frequency circuits for RF matching and to achieve low loss as well as high power.

Working Principle

The working principle of a fixed inductor is based on the fact that an electric current flows in a loop, creating a magnetic field. According to Faraday’s law of induction, a changing magnetic field will induce an electromotive force (emf) in the loop, which will oppose the change which caused it. This EMF acts as a counter electromotive force (CEMF) and will reduce the flow of electric current in the loop. In other words, the inductor opposes change in the electric current in the loop.

The ELL-SFG331MA is a common fixed inductor with an inductance value of 33μH. It has a current rating of 1.85A and it is made from a high-performance ferrite core material. It has a wide operating temperature range of -55 to 125℃.
