Fixed inductors, or coils, are electronic components used to create a fixed magnetic field, usually with the purpose of storing energy or providing impedance to alternating currents. The SRU5011-4R7Y is a type of fixed inductor developed by Murata, a Japanese manufacturer of components and assemblies for electronics applications. In this article, we will discuss the application field and working principle of the SRU5011-4R7Y.

The SRU5011-4R7Y is a high-frequency ceramic core inductor, primarily used in circuits requiring tight energy storage capabilities and impedance control. It features a core made of AIN (Alumina Nitride), a type of ceramic, for low current losses. Its primary applications include Power Supply Circuit, PFC Circuit, and Converter, which all require tight energy storage and impedance control. It is also used for signal filters, attenuation circuits, and high-frequency chip components.

The SRU5011-4R7Y is a high performance inductor, with a frequency range of 100kHz to 2.5MHz. Its self-resonant frequency is high, at 5MHz, and it has a Low Losses core material, able to provide good impedance performance over a wide frequency range. The SRU5011-4R7Y also features a High Q-factor, of 100 at 100kHz, adding to its flexibility in applications.

The working principle of a fixed inductor is fairly straight forward. An electro-magnetic field is created when current passes through the inductor, and this field stores energy in the form of magnetized flux. Current passing through this electro-magnetic field will induce a voltage, and this voltage can be used to oppose the original input of current, providing a type of impedance control. This is known as inductance.

The SRU5011-4R7Y was designed to take advantage of this principle. It features a tightly controlled electro-magnetic field and a high Q-factor, providing excellent energy storage and impedance control capabilities. Its core material of AIN also ensures low current losses, cutting down on power distribution inseficiencies.

In conclusion, the SRU5011-4R7Y is a highly efficient fixed inductor, developed for power supply, PFC, and converter circuits. It is renowned for its high Q-factor, tight impedance control capabilities, and low current losses. With its wide range of applications, the SRU5011-4R7Y is an ideal choice for any designer looking for high performance inductors.
