Fixed inductors are electronic components that have a fixed inductance and are used in various areas of electronics design. This article explores the application field and working principle of a specific example - 1638R-08G.

Application Field of 1638R-08G

The 1638R-08G is a high-performance, high-frequency, self-shielding inductor that’s specifically designed for use in constrained spaces and densely populated pc boards. It delivers a high inductance value in a small, compact package. The 1638R-08G is ideal for use in applications such as DC-DC converters, switched-mode power supplies, antennas and receivers, wireless communications, voltage regulators, signal processing, and memory circuits.

Some of the advantages of using 1638R-08G inductors include low DCR and self-leakage values, high frequency range up to 1GHz, and low core loss. The 1638R-08G offers a wide range of inductance values from 0.01uH to 6.8uH, making it suitable for a variety of applications. The small size of the device also makes it practical for use in a variety of high-density applications, such as cell phones, tablets, and other portable devices.

Working Principle of 1638R-08G

The working principle of the 1638R-08G is based on the same principles as any other fixed inductor. A fixed inductor consists of a coil of wire wound around a core made of magnetic material. This creates an electromagnetic field in the core when an electrical current is passed through the coil. The resulting inductance depends on the number of turns in the coil, the cross-sectional area of the core, and the relative permeability of the core material.

The 1638R-08G is constructed using high-quality ferrite core material and silver-plated wires for high frequency applications. The ferrite core helps to minimize the core losses produced by the coil and keep the inductance stable. The high quality silver-plated wires ensure that the current flow is uninterrupted and help to minimize the voltage drop across the device. The low DC resistance values provide better power efficiency and low EMI noise.

The 1638R-08G also offers the advantage of self-shielding, which helps to reduce the interference between different circuit paths. This is achieved by wrapping the wire winding around the core in multiple layers of insulation, which helps to prevent electrical currents from dissipating from the core.

The 1638R-08G is a great choice for applications that require high performance and high frequency operation in constrained spaces. It offers a range of advantages, including high frequency range, low DCR and self-leakage values, and low core losses. It is also much smaller than conventional inductors, making it ideal for use in portable electronics applications.
