SRN8040-4R7Y Application Field and Working Principle

Fixed inductors are essential electronic components widely used for frequency selection, oscillation or tuning in various circuits. This article will briefly explain the application field and working principle of the SRN8040-4R7Y fixed inductor.The SRN8040-4R7Y is a high-performance fixed inductor with low DC resistance and a high inductance range (~4.7 μH to 10 μH). It is designed to provide better inductive performance with lower DC resistances. Therefore, the SRN8040-4R7Y can be used in various applications requiring a high inductance and reliable operation.The SRN8040-4R7Y fixed inductor is usually used in high-power converters, power electronics, multiplexers, wireless charging circuits, DC/DC converters, LED lighting, AC/DC converters, or any other application that requires high inductance or high current operation. Its excellent performance and excellent reliability make it suitable for a wide range of applications.The working principle of the SRN8040-4R7Y is based on the concept of inductance. Inductance is the property of a circuit to oppose any changes in the current or voltage applied to it. When current is applied to the inductor, a magnetic field is generated inside the coil due to the inductance. This magnetic field induces an electromotive force (EMF) inside the coil which opposes the applied current or voltage. The induced EMF is known as the “back EMF”.The resistance of the inductor causes a voltage drop across the windings which can be calculated using Ohm’s law. The total current flowing through the inductor can be calculated from the voltage and resistance. The total current determines the inductance of the component which is defined as the ratio of the total current to the rate of change of the current.The SRN8040-4R7Y fixed inductor is designed to provide a high level of inductance and low DC resistance. It offers a wide range of inductance values and a low resistance range. This helps in providing optimal efficiency when operating at high currents.In summary, fixed inductors are important components widely used in various circuits. The SRN8040-4R7Y fixed inductor is a high-performance component which provides an excellent combination of high inductance and low DC resistance. Its working principle is based on the principle of inductance and it is suitable for a wide range of applications.
