18R155C

Fixed inductors are electronic components that can store electrical energy in the form of a magnetic field in an inductor coil. The 18R155C device is one of the many types of fixed inductors available on the market. This device is designed for use as a filter or decoupling element in telecommunications applications such as cell phones and other mobile devices, as well as in consumer electronics applications such as televisions, DVD players and other audio/video equipment.

The 18R155C is a miniaturized, single-coil, type 18R1 inductor designed for use in a variety of applications. This component features an operating temperature range of -40°C to +125°C, and is rated for use at up to 105°C. It has an inductance range of 0.51µH to 15µH and a maximum DC current rating of 0.6A. It is also available with a tin-plated copper winding, allowing for improved thermal conduction and long-term reliability.

The 18R155C uses a simple construction comprising of an inductor coil wrapped around a core material, which is typically made of ferrite or powdered iron. These materials are chosen for their excellent ability to store magnetic energy. The core functions as a shield, providing greater stability and increasing the efficiency of the inductor.

The working principle of an inductor is based on Faraday’s law of induction. This states that when a conductor, such as a wire, is subjected to a changing electric field, it produces an induced voltage, which creates an electric current. This effect is known as ‘self-induction’ or ‘inductive reactance’ because the induced voltage opposes the original current and causes the current to decrease. In other words, the inductor resists changes in the electrical current.

In a fixed inductor such as the 18R155C, the induced voltage is proportional to the rate of change of current. The inductor is designed to allow an AC or pulsed current to flow in one direction only, creating the desired filtering effect. This type of inductor is commonly used in power supplies and high frequency switching circuits for filtering and decoupling purposes.

In summary, the 18R155C is a type of fixed inductor used for filtering and decoupling purposes in a variety of applications. This component features a simple construction, rated for use up to 105°C, and an inductance range of 0.51µH to 15µH. It works on the principle of Faraday’s law of induction, creating an induced voltage which opposes the original current and causes the current to decrease. This type of component is widely used in telecommunications and consumer electronics applications.
