Fixed inductors like CIGW404012GM4R7MLE are passive two-terminal electrical components, which are used for storing energy in the form of magnetic fields. They are also known as chokes and are often used in power supplies, filters, antenna and shield cabling, and radio receivers.

Fixed inductors are composed of an encapsulated core wrapped in a coil of insulated wire, typically made from aluminum. The core is usually made of ferrite or other magnetic material which stores the generated magnetic energy, while the insulation prevents short-circuits. Fixed inductors come in different shapes such as axial, radial, and circular, depending on the application.

The operating principles of fixed inductors are quite simple. When the current passes through the coil it creates a magnetic field, which then induces a voltage in the coil. The induced voltage is proportional to the current passing through the coil, and is known as the inductance voltage. In the case of CIGW404012GM4R7MLE, an inductance voltage of 0.6 V/A is created.

Fixed inductors can be used in a variety of applications. In AC power supplies, they are used to filter out high-frequency noise, which can damage sensitive electronic parts. In DC power supplies, they can act as filter chokes to reduce noise. They are also largely used in the field of RF engineering, where they can be used as antenna couplers, filters, and band-pass filters. Fixed inductors can also be used in audio circuitry for equalizers and loudspeaker crossovers.

CIGW404012GM4R7MLE is a fixed type inductor made with ferrite material and is most suitable for audio signals. It has a 4-layer construction ribbon-style coil with a 30% tolerance.
