Fixed inductors are electronic components made of wire wound around a core material or a ferromagnetic core. This includes a range of inductors such as air core, ferrite core, iron powder core, and toroidal wound inductors. The goal of the fixed inductor is to store electrical energy as a magnetic field and to oppose a change in current that occurs when the inductance of the inductor changes. A fixed inductor consists of a coil of wire that is wound around a core material or a ferromagnetic core. The core material is usually a ferrite, iron powder, steel or ceramic. The shape and size of the core and the number of turns in the coil of wire determine the inductance.

The CW201212-R27J series of fixed inductors falls under the Fixed Inductors category. This series of inductors feature a high current rating of up to 27A. These fixed inductors feature an operating temperature range of -30°C to +155°C. The CW201212-R27J fixed inductors have a nominal inductance of from 1.0uH to 1000uH. There is a wide variety of package sizes available for this series of inductors with footprints ranging from 6.3mm x 7.7mm to 21.5mm x 25.5mm. Manufacturing techniques such as high-frequency taping (HFT), surface mount technlogy (SMT), and hand winding (HW) can be used to produce these series of inductors.

The working principle of a fixed inductor is based on Faraday\'s law of induction. When a current passes through a fixed inductor, a opposing or back EMF (electromotive force) is generated due to the rate of change of the magnetic flux lines within the core material. This opposing EMF results in a decrease in the magnitude of the applied current. In other words, the inductor acts as an AC resistor due to its inductive reactance. The inductor resists the rate of change of the current which in turn creates a voltage drop across the inductor.

The CW201212-R27J series of fixed inductors also feature a stable inductance value over a wide range of temperatures and frequencies. This makes these series of inductors ideal for high-frequency applications such as automotive, communications, and consumer electronics. The high operating temperature range of these series of inductors also makes them suitable for use in power converters, DC-DC converters, and other power applications where higher operating temperatures are encountered. Additionally, the various sized packages available for these series of inductors makes them suitable for applications where the physical size is a constraint.

Fixed inductors are essential components in many types of circuits. The CW201212-R27J series of fixed inductors provide many advantages such as high current rating, stable inductance over a wide range of temperatures and frequencies, and a wide variety of package sizes. These features make the CW201212-R27J series of fixed inductors ideal for a variety of applications such as automotive, communications, consumer electronics, power converters, and DC-DC converters.
