Introduction

Inductors, also known as coils or components, are two-terminal electrical devices that store energy in the form of a magnetic field. Inductors are widely used in electronic circuits in order to provide filtering, impedance matching and to maintain a desired impedance level within a given circuit. They are also typically used to ensure that signals maintain their integrity when travelling between electrical components. Fixed inductors, as implied by the name, are fixed components which are generally used for applications that require less flexibility, such as power transformers, inductors, and power supplies.The SRR1210A-6R8Y is a fixed inductor manufactured by Bob Smith Electronics that offers a range of features and capabilities for industrial applications. This article explores the application field and working principles of the SRR1210A-6R8Y.

Description of the SRR1210A-6R8Y

The SRR1210A-6R8Y is a fixed inductor designed for industrial applications which require exact, reproducible operation. It is composed of two pieces of ferromagnetic material, separated by an insulating cover. The inductor is physically small in size, measuring only 2.5 x 2.5 x 0.5 mm (10-6 m) – making it ideal for applications where space is limited. The physical size and shape of the inductor also make it resistant to mechanical vibrations.The SRR1210A-6R8Y has a wide range of features, including inductance values ranging from 10µH to 100µH, a rated DC or AC test current of up to 3 amperes, a rated frequency of up to 20 MHz, and a rated power of up to 0.5 Watts. The operating temperature range is from -20°C to +75°C, allowing it to be used in a variety of environmental conditions. The inductor also offers a low DC resistance range of between 0.1mΩ and 6.8mΩ.

Application Field and Uses of the SRR1210A-6R8Y

The SRR1210A-6R8Y is commonly used in industrial applications that require precise operation, such as computer network cabling systems, general electronic devices, printed circuit boards, LCD displays, and testing devices. It is also commonly used in filter circuits, power supplies, and transformer circuits. The SRR1210A-6R8Y is highly recommended for applications that require long-term stability and high reliability. Its physical size and strength make it especially well-suited for applications where space is limited or where there is a possibility of being exposed to mechanical vibrations.

Working Principle of the SRR1210A-6R8Y

An inductor is a device that stores energy in the form of a magnetic field. This is achieved by creating a current loop with the inductor – in which any changes in the current flow will induce a magnetic field. When a current flows through an inductor, the magnetic field generated by the current causes a reaction force to be produced, which is equal and opposite to the current flow. This reaction force, known as "back EMF", opposes any changes in the current. This is why inductors are sometimes referred to as "reacting components". The SRR1210A-6R8Y is designed to have a very low DC resistance, allowing it to more effectively store energy in the form of a magnetic field. This allows it to provide more reliable operation over a wide range of frequencies.

Conclusion

The SRR1210A-6R8Y is a fixed inductor designed for industrial applications which require exact, reproducible operation. It is small in size and offers a range of features, including inductance values ranging from 10µH to 100µH, a rated DC or AC test current of up to 3 amperes, and a rated power of up to 0.5 Watts. It is commonly used in filter circuits, power supplies, and transformer circuits. The SRR1210A-6R8Y works by creating a current loop with the inductor, in which any changes in the current flow will induce a magnetic field that opposes the current flow. Overall, the SRR1210A-6R8Y is an excellent choice for applications that require precise operation and long-term stability.
