Fixed Inductors: ER1641-182JS

Fixed inductors are electronic components designed to store electrical energy in an inductive coil and convert electrical energy into magnetism, or vice versa. Generally composed of a coil of wire enclosed in a metal, ceramic, or other non-conductive housing, fixed inductors are used in a variety of electronic circuit designs to couple signals, create filters, oscillate signals, and serve as timing circuits. The ER1641-182JS is a type of fixed inductor popular for its advanced features and reliable performance.The ER1641-182JS is a small through hole inductor that offers excellent electrical characteristics with minimal size and weight. With a 0.15 Ohm DC resistance and a 0.039mH inductance, it operates at a 100 mA current rating and a 2K Hz frequency. The inductor is constructed using a high purity, annealed copper winding for maximum inductance stability and reliability. This inductor also features a tinned copper core and a high-temperature insulation for superior performance in all environment and temperature conditions.In general, the ER1641-182JS provides exceptional amplitude and homogeneity in its inductance range, as well as being extremely secure and energy efficient. This fixed inductor has a wide range of applications including switch mode power supplies, LED controllers, RF systems, power supply circuits, and many more. It is highly suitable for use with LEDs, BLDC motors, and various power supplies that require high efficiency, low EMI, long lifetime, high reliability, and low inductance.The working principle of a fixed inductor is based on Faraday\'s law of electromagnetic induction. When an electric current is sent through a wire coil, it creates a magnetic field. The magnetic field induces an electromotive force (EMF) in the coil, causing it to produce a voltage. This voltage, in turn, induces an electric current in the wire coil, creating a self-regenerating transfer of energy back and forth between the electric charge and magnetic field. This transfer of energy is known as electrical induction.In the case of the ER1641-182JS, this electromagnetic induction is used to achieve the desired electrical characteristics in the inductor. The tinned copper core produces a small core loss that helps keep energy efficiency high. The high-temperature insulation ensures that the inductor can withstand extreme temperatures in a wide variety of applications. The annealed copper winding helps maintain the inductance range ensuring that the inductor constantly generates the desired electric current throughout its operating range.Overall, the ER1641-182JS is an excellent fixed inductor that offers superior electrical characteristics, high efficiency, and reliability. It is designed to provide excellent performance in a variety of applications, offering a lengthy product life and reliable performance.
