Fixed Inductors

Fixed Inductors are used as components in electrical and electronic circuits. They are used to help regulate current and bias, store energy, or block signals of alternating current. The S0402-12NF2D is one type of fixed inductor.

S0402-12NF2D Application Field

The S0402-12NF2D is a low-profile, low-resistance, shielded power inductor with a power rating of 12 watts. It can be used in a variety of applications, such as power supplies, DC/DC converters, power amplifiers, high-frequency switching, resonant circuits, broadband communication, and RF modules. This inductor can also be used in automotive and consumer electronics applications, including car audio amplifiers, power filters, audio amplifiers, and switching regulators.

S0402-12NF2D Working Principle

The S0402-12NF2D works on the principle of electromagnetic induction. Electromagnetic induction is the production of an electric current in a conductor when subjected to a changing magnetic field. This inductor produces a voltage when subjected to a changing current. This electric current will continue to flow as long as the current is changing. The inductor also contains a core material, which is usually a ferrite material. This material acts as a central area around which the electric field is concentrated. This helps to increase the inductance of the inductor.

S0402-12NF2D Advantages

The S0402-12NF2D has several advantages over other types of inductors. First, the low-profile design of the S0402-12NF2D allows for easy installation in narrow spaces. Its low-resistance allows for increased current handling, while its shielded design offers better protection from EMI and RFI. Another advantage of the S0402-12NF2D is its ability to operate at higher frequencies, which is beneficial for applications that require fast switching times. Additionally, the inductor’s high current rating allows for heavier load current or higher quality operation.

Summary

The S0402-12NF2D is a fixed inductor that is used in many electronic circuits. Its low-profile, shielded design allows for easy installation in narrow spaces, and its high current rating allows for higher quality operation. The S0402-12NF2D works on the principle of electromagnetic induction, and its properties make it useful for applications such as power supplies, DC/DC converters, power amplifiers, and more.
