Fixed Inductors have a wide range of applications in electronics, especially in filtering and resonant circuits. One of the most popular fixed inductors is the ILSB0805ER3R9K. It is a low DC resistance through hole inductor designed for automotive applications. This inductor is designed to be used in high voltage DC-DC converters, automotive powertrain, power supplies, and other applications that require low DC resistance.

The ILSB0805ER3R9K is a two-pin inductor with a magnetically shielded construction. It features high current ratings, low DC resistance and a wide operating temperature range of -40°C to 85°C. It is also RoHS and halogen free, making it an excellent choice for environmental friendly applications. The inductance values range from 370 nH⁻7.4 mH, depending on the part number.

The working principle of a fixed inductor is based on the concept of induction. It consists of a coil wound with a ferromagnetic core or an air-filled film made of iron or other magnetic materials. When an electric current is passed through the coil, it produces a magnetic field which induces a voltage in the opposite direction. This electromagnetic interaction creates a resistive force that opposes the change in current, resulting in the inductive effect.

The inductance of the ILSB0805ER3R9K depends on the number of turns, type of core material used, and size of the wire. The higher the number of turns, the higher the inductance. Also, the core material affects the outcomes. A ferromagnetic core will typically have higher inductance than an air core. Since inductors are electromechanical devices, they are affected by physical vibration and heat and therefore, have a temperature coefficient value.

The ILSB0805ER3R9K is a popular choice for automotive systems due to its high current ratings, low DC resistance, wide operating temperature range, and RoHS and halogen free construction. It is used in high voltage DC-DC converters, powertrain applications, and power supplies. It is also often used in filtering and resonant circuits because of its wide range of inductance values.

The ILSB0805ER3R9K has proven to be an invaluable tool for vehicle electronic systems. It is a reliable and energy efficient part that is easy to use and install. With its combination of features, this fixed inductor offers an extensive range of automotive applications.
