Fixed inductors are used to store electrical energy in the form of magnetic fields. The main application of inductors is to provide electrical isolation in circuits and to filter out certain frequencies. The SD3118-681-R is a fixed inductor that is designed for use in high-frequency applications.

The SD3118-681-R inductor has a rated inductance of 0.68 µH, and a maximum inductance of 0.76 µH. The part also has a rated current rating of 1.5 A and comes in a 0603 package. The maximum operating temperature of this device is +85°C. Additionally, its rated DC resistance is 0.51 Ω. The inductor also has a ferrite core material, which makes it suitable for high-frequency applications.

The SD3118-681-R fixed inductor is usually used in high-frequency applications such as audio, RF and power line filtering, and in high-frequency drivers. It is also widely used in switching converters, low-harmonic AC-DC power supplies and in resonant circuit applications for switching regulators.

The working principle behind the SD3118-681-R fixed inductor is based on Faraday\'s law of induction. According to this law, when a current flows through a coil, a magnetic field is generated, which in turn induces a voltage in the coil. This induced voltage opposes the applied voltage, resulting in a decreasing current in the coil. This process is known as inductive reactance, and it is what helps to filter out certain frequencies in electronic circuits.

The SD3118-681-R fixed inductor is a reliable and efficient device that helps to isolate electrical circuits and filter out certain frequencies. With its well-defined characteristics and long service life, it is perfect for high-frequency applications such as RF, power line, and audio filtering.
