Fixed Inductors

When an electric current is passed through a conductor, it generates an electro-magnetic field. Similarly, when a conductor is placed in an electro-magnetic field, a current is induced in it. This phenomenon is called electromagnetic induction. Fixed inductors work on this principle. S0603-151NF3E is a type of fixed inductor which is used in a wide variety of applications such as switching power supplies, converters, amplifiers, signal processing, etc.

Applications of S0603-151NF3E

S0603-151NF3E is a miniature chip fixed inductor which is capable of handling high power loads. It is mainly used in switching and linear power supplies and converters regulating the output current. This inductor is also used in battery-operated equipment where an efficient power management is necessary. It is also used in audio devices like amplifiers to filter the audio signals from high frequency components entering the input. The inductor is also used in radio frequency circuitry such as local oscillators, oscillators, mixers, etc.

Working Principle of S0603-151NF3E

When an electric current is passed through a tight coil wrapped around the core, an electro-magnetic field is generated. The S0603-151NF3E uses a ferrite core which is metal powder combined with ceramic powder with special characteristics like high magnetic permeability, high saturation flux density, and a low core loss (eddy current loss). The inductance of the core is dependent on the number of turns in the coil and the size of the core. The ferrite core is wound around with thin copper coil conductors which have a high insulation resistance.

The inductance of the coil in S0603-151NF3E can be varied by changing the number of turns or the core size. When an alternating current is applied to the coil, an oscillating electro-magnetic field is set up. The alternating current flowing through the coil is a combination of an AC component and a DC component. The AC component is opposed by the inductance of the coil. The DC component is smoothed by the inductance. Thus, the inductor acts as a low pass filter. It helps to regulate the load current and minimize the generation of high frequency noises.

The S0603-151NF3E is available in a sealed case and is rated from 4 to 100µH. It is a surface mount device measuring 3.0mm x 3.2mm x 1.9mm with a maximum DC current rating of 1.5A. Its inductance tolerance is ±30% and the operating temperature ranges between -40°C to +125°C.

In conclusion, S0603-151NF3E is a fixed inductor which is widely used in various types of electronic circuits such as switching power supplies, converters, amplifiers, and radio frequency circuits. It uses a ferrite core wound with a thin copper coil to generate an attractive electro-magnetic field. The inductor is relatively small and has a high current rating. It helps to regulate current and minimize noise. It has a wide operating temperature range and a high inductance tolerance.
