Fixed inductors are passive components used in electrical circuits consisting of coils of wire that store energy in the form of a magnetic field. They are commonly used to filter signals, create oscillations, and create pulse waves. Andrews 2890-38H is a popular fixed inductor, and its application field and working principle are explained in detail below.

The Andrews 2890-38H is an air core, non-shielded inductor with a construction made of laminated copper coil windings. It is commonly used for audio, telecommunications, and EMI filtering, and is one of the leading inductors for use with surface-mount devices. With its high allowable current and low resistance, it is ideal for high frequency applications, and it can withstand temperatures up to 180°C. It is made with a core material that provides excellent saturation performance and thermal conductivity.

The Andrews 2890-38H is designed to create of a low impedance path to ground and is often used in power conditioning and harmonic filtering applications. It is also ideal for function generators, wave traps, and DC-to-DC converters. The inductor is able to reduce the electrical noise generated by these components, while still maintaining the electrical performance. It is also used in rf amplifier baluns, motor drives, and signal generators.

The working principle of the Andrews 2890-38H is based on the principle of electromagnetism. When a current passes through the copper coil windings on the inductor, a magnetic field is created that stores energy in the form of an electric field. The magnitude of the electric field depends on the amount of current flowing, the strength of the magnetic field, and the inductance of the coil. When the electrical current is turned off, the electric field dissipates and the energy stored in the coil is released.

The Andrews 2890-38H is a useful and versatile fixed inductor, and its wide application range makes it an ideal choice for many electrical projects. Its robust construction and high power handling makes it suitable for high temperature environments, and its magnetism properties are ideal for signal and power conditioning. With its ability to reduce electromagnetic interference, it is a great choice for use in audio, telecommunications, and EMI filtering. It is an excellent choice for any project requiring an efficient, reliable fixed inductor.
