Fixed Inductors are an important type of electronic component. They are used in circuits to store energy and control the flow of current in various applications. The S1812R-393F is one such type of inductor and has a variety of applications and a unique working principle.

The S1812R-393F is a specifically designed fixed-frequency inductor. It is made of SMNi core material and a high-temperature epoxy resin, which makes it highly reliable and durable in operational use. It is designed for use in applications such as switching power supplies, inverters, and motor drives. It has a rated inductance of 3.9 mH and a maximum DC resistance of 0.17 ohms. It can handle rated current of up to 14.2A, and can handle up to 10A of instantaneous current.

The way the S1812R-393F inductor works is through Faraday’s Law of Induction. This law states that a changing magnetic field will induce a voltage in a conductor placed within the field. The S1812R-393F has two copper windings which are wrapped around the core material. This core material acts as the magnetic field and the changing current passing through each winding induces a voltage in the other winding proportionate to the current. The induced voltage is oppositely directed and equal in magnitude as the two currents flowing through the inductor, which is what makes it useful for controlling the current in applications such as switching power supplies.

The S1812R-393F is available in various physical sizes and package types. It comes in a number of different standard footprints from 7.2 to 15.1 mm wide and up to 40 mm long. The standard package types include leaded die-cast aluminum, plastic radial, and dual in-line SMT packages. It has a storage temperature range of -40°C to +85°C and an operating temperature range of -25°C to + 85°C, making it suitable for a wide range of applications.

The S1812R-393F fixed inductor is one of the most popular types of fixed inductors available on the market today due to its excellent performance, high reliability, and cost efficiency. It is well suited for applications such as switching power supplies, inverters, motor drives, and other power supply applications. Its unique Faraday’s Law of Induction-based working principle allows it to control current which in turn allows for highly efficient operation. Its various physical sizes, package types, and wide temperature range make it suitable for a number of different applications and it can be an invaluable addition to any system that requires a reliable and efficient fixed inductor.
