Fixed Inductors

Inductors are devices that possess the ability to store energy in the form of an electromagnetic field when electric current is passed through them. Fixed inductors are specifically designed to have a steady inductance and usually are either wound on a ferrite or powdered-iron core. Fixed inductors are used frequently in various applications to filter harmonic noise, transmit signal, and store energy. One of the most versatile models of fixed inductors is the LK1005R27K-T application. This model of fixed inductors is designed with 27 micro henries of inductance and a maximum DC current of 500mA. Due to its low DC resistance of 1.4 Ohms, the LK1005R27K-T provides a high saturation current of 8.4 amperes, as well as a high working frequency response up to 1MHz. This model is also able to sustain a range of applied temperatures ranging from -55°C – 150°C, allowing for a range of applications in a variety of environmental and working conditions. The primary purpose of the LK1005R27K-T is to reduce EMI interference caused by high-speed digital signals. In many high frequency applications, harmonics and noise may be generated as the signal propagates through the circuit, causing interference with other systems. By utilizing the LK1005R27K-T inductor, the effects of EMI interference is minimized, allowing the signals to pass through without being distorted by noise. Aside from acting as EMI filters, fixed inductors are also used in LC filters and impedance matching networks. In LC filters, the inductors act to reduce the effects of harmonic noise from traveling through the circuit. When used in impedance matching networks, fixed inductors are used to transform the impedance of a circuit, allowing the signals to flow freely between the different components within the network. The mechanism behind how a fixed inductor works is fairly simple. When a direct current is passed through an inductor, an electromagnetic field is generated around the induction coil. This field is then able to effectively store energy proportional to the current flow in the induction coil. When the current is changed, the energy stored is then permitted to be based out, acting as a filter or other circuit functions. In conclusion, the LK1005R27K-T is a multi-purpose fixed inductor model that can be used in a range of applications for different purposes. It is an effective tool for digital signal filtering and EMI control, as well as for LC filtering and impedance matching. Its high-saturation current of 8.4A and low DC resistance of 1.4 Ohms allows the LK1005R27K-T to provide clean and reliable signal transmission in a range of environmental and working conditions. With its versatile functions and reliable performance, the LK1005R27K-T model of fixed inductor is a must-have for any circuit design application.
