Fixed Inductors are a type of electronic component that creates a magnetic field around a wire which is then used to store energy. The S1812R-392F is a type of Fixed Inductor that is typically used in switching power supplies, DC-DC converters, and other high frequency circuits. The inductor is designed to reduce EMI (electromagnetic interference) and provide better AC ripple attenuation in the circuit.The S1812R-392F is a surface mount, 2.2µH shielded inductor, able to handle currents of up to 1.9A. The inductor has an 800kHz maximum operating frequency, a 0.02-ohm winding resistance, and a 0.18µH minimum inductance. It has a 17.25mΩ DC resistance that limits current flow and an acoustic noise level of 20dB, making it ideal for low-noise audio applications. The S1812R-392F’s construction features a 26% zinc alloy core, which provides high stability and heat dissipation for the component’s winding resistance. The inductor’s wire has been tested to ensure a high-purity insulation and low electrical noise. The inductor is then wrapped in a shielded nickel-plated case, which reduces noise and allows for heat dissipation.The S1812R-392F’s working principle is based on the law of electromagnetism, which states that a current flows through a wire when an electric field is applied to it. This is known as the “induced current” which creates a magnetic field around the wire. The induced current flow creates an opposing force to the electric field, known as an “induced electromotive force”, which limits the rate of current flow. This is the working principle of the S1812R-392F.The S1812R-392F\'s application field is vast. It can be used in automotive power supplies, telecommunications systems, and avionics. It is also used in consumer electronics, such as portable music players, TVs, and gaming consoles. Due to its low noise and stable performance, it is often used in audio applications, such as sound processors and amplifiers. Additionally, its high frequency and stability make it ideal for use in switch mode power supply circuits.The S1812R-392F is an important component of high-performance electronics and is used in a wide range of applications. Its features, such as high stability, low noise, and high operating frequency, make it an ideal choice for low-power electronic designs. In addition, the inductor’s shielding allows for less interference from external sources and its zinc-alloy core offers increased heat dissipation. These features make the S1812R-392F a great choice for use in a variety of electronic applications.
