Fixed inductors, also known as coils, are a type of passive electrical component used in many different electronic circuits. They are composed of a core material, typically made of metal, ferrite or air, and two conductors wrapping around the core, adding inductance to the circuit. The inductors come in a variety of shapes and sizes and can be used to filter out particular frequencies, filter out negativity, regulate current, create delays for circuitry, and can also be used as transformers. The 4379-104KS is a specific type of fixed inductor from Ohio-based manufacturer PMK.

The 4379-104KS is a high-end fixed inductor, designed to handle higher power levels and to be able to withstand punishing temperatures and environmental conditions. The 4379-104KS is constructed with a core made of a ferrite mix and wrapped with enameled copper, which is intended to help keep the inductance stable regardless of temperature variations. It has a rated inductance of 104 mH +/-20%, a DC resistance of 0.64 ohm, and is designed to handle up to two amps of current. Additionally, it is rated to operate between -40°C to +140°C.

In terms of applications, the 4379-104KS is a versatile component that can be used in many different types of electronic circuitry. It is particularly suited to high-power, high-frequency applications such as inverters, switching regulators, lighting ballasts, and automotive inverters. It can also be used as an energy storage device to provide a “flywheel effect” in situations where sudden power spikes are necessary, such as medical devices and automotive power systems. Additionally, the 4379-104KS is well-suited to power supplies, power amplifiers, and motor drives.

The working principle behind the 4379-104KS is the same as any other fixed inductor. When a current is applied to the inductor, it creates a magnetic field around the core, which induces a voltage in the second winding on the inductor. This voltage in the second winding then opposes the original current, working to slow it down as it passes through the inductor. The amount of voltage induced is determined by the inductance of the inductor, which is a function of its core material and size. The 4379-104KS is designed to provide consistent inductance values regardless of temperature variations, making it an ideal choice for high-power applications.

In conclusion, the 4379-104KS fixed inductor from PMK is a versatile and reliable component designed to handle higher power levels and temperature extremes. It can be used in a wide variety of applications, including power supplies, inverters, switching regulators, medical devices, and automotive inverters. The working principle behind the 4379-104KS is the same as all other fixed inductors, relying on the induced voltage in a secondary winding to oppose the original current, creating a “flywheel effect” when needed. Together, all of these features make the 4379-104KS a great choice for any high-power or high-frequency electronics project.
