Fixed inductors, also known as non-moving or static inductors, are electrical components which store energy in a magnetic field. The conventional inductor is a coil of wire wound around an iron core, but the use of air gaps or ferrite cores made the inductors more efficient in applications needing high frequencies. The construction and size of the inductor will vary depending on the application.

Inductors are typically used in applications with high frequencies. From low frequency (d.c) applications such as voltage regulation; to high frequency a.c. applications such as filter, resonator and amplifier stages, inductors have a broad range of applications. In digital circuits, inductors are usually used in filters and noise suppression.

74458147 is a type of fixed inductor. It is designed for general purpose applications and is suitable for use in AC and DC circuits. It is constructed with a high temperature grade ceramic core and windings of enameled copper wire. The core and coil material has excellent durability and temperature stability. The inductance range of this type of inductor is from 0.15 μH to 2.2 μH in four values, and it is rated for operating temperatures between -25°C and +125°C.

The basic working principle of a fixed inductor is that when an alternating current is applied through the device, a magnetic field is created. This magnetic field then interacts with the current to generate a fluctuating voltage across the inductor that opposes the current change. This process is known as "self-inductance" and is essential for maintaining a stable voltage and frequency in a circuit.

The 74458147 fixed inductor offers benefits such as excellent temperature stability, high frequency operation and a wide range of inductance values. It is designed for applications such as AC/DC switch mode power supplies, telecommunications, consumer electronics, and automotive systems. The unit can be used in both through-hole and surface mount configurations, providing maximum versatility for design engineers.

In summary, the 74458147 fixed inductor is a reliable and versatile electrical component suitable for different applications in the communications, consumer electronic, and automotive industries. Its construction and features enable it to operate with high efficiency at high frequencies, while providing excellent temperature stability and a wide range of inductance values. This makes the 74458147 fixed inductor an ideal component for many of today\'s electrical device designs.
