SD12-100-R Inductors, Coils, Chokes

Fixed Inductors

Fixed inductors are also known as coils, chokes and reactors, and are electrical components that have the ability to store energy in the form of magnetic flux. They are usually wound on a core made out of ferrite, steel or a combination of both. They are most commonly used in the power electronics industry in applications such as power supplies, motor drives and inverters.

SD12-100-R is a type of fixed inductor manufactured by Murata Electronics, a leading electronics manufacturer. It is a small, surface-mount component ideal for use in high-density circuit designs. It has a nominal inductance of 12 µH and a rated current of 2.7A, meaning it can handle moderate loads without suffering from significant losses. It is also rated for a temperature range of -40°C to +85°C, making it suitable for use in a wide range of operating conditions.

Application Field

SD12-100-R inductors are mainly used in switching power supplies, frequency converters and electronic circuitry. Their primary purpose is to store energy in the form of magnetic flux and filter out high-frequency noise. They are often part of a switching power supply design, where they provide filtering, energy storage and line regulation. They can also be used as chokes, which limit the AC current flowing in a circuit.

Working Principle

The primary function of an inductor is to store energy in the form of magnetic flux, and this is achieved by wrapping multiple turns of wire into a coil. When an alternating current passes through the coil, the generated magnetic flux creates an opposing Voltage, i.e. the coil is able to store energy in the form of magnetic flux. The energy is then released when the current passes in the opposite direction, allowing it to flow in a steady manner.

The SD12-100-R inductor is designed to have a minimum inductance of 12 µH and a maximum rated current of 2.7A. This allows it to effectively filter out high frequency noise, while still allowing for steady and reliable current flow. The inductor is also rated for a temperature range of -40°C to +85°C, making it suitable for use in a wide variety of operating conditions.

In summary, the SD12-100-R inductor is a small, surface-mount component that is ideal for use in high-density circuit designs. It is mainly used in switching power supplies, frequency converters and electronic circuitry, where its primary purpose is to store energy in the form of magnetic flux and filter out high-frequency noise. It is also rated for a temperature range of -40°C to +85°C, making it suitable for use in a wide range of operating conditions.
