Fixed Inductors are electronic components designed to store energy in the form of a magnetic field when current passes through them. DR73-4R7-R is a type of fixed-inductors that is commonly used in various applications. This article explores the different applications of DR73-4R7-R and how it works.

DR73-4R7-R fixed inductors can be used in a variety of industrial, automotive, and consumer electronics applications. It is commonly used in wide-area, automotive, and embedded applications including sensors, motor drives, LED lighting, switching regulators, and RF applications. It is also widely used in 15 W application such as power distribution in mobile and communication systems, as well as in high-end home audio streaming.

The DR73-4R7-R fixed inductor is made up of a high-grade ferrite material and ion-plated copper winding. The device features a double-level high-frequency spiral winding minimizes perturbation and interference, making it highly reliable and durable. The device is equipped with etching thick film technology to increase the power conversion efficiency and reduce EMI emission. It has a wide set of working temperature range from -25°C to +85°C.

The DR73-4R7-R fixed inductor works by taking in the input current from one end of the windings and using it to create a magnetic field. This magnetic field is then held in place until the current is removed, at which point it will collapse and release the stored magnetic energy back into the circuit. The inductance of the device is determined by the number of turns of the wire on the core and the magnetic permeability of the core material. The inductance can be increased by increasing the number of turns of wire and/or using a material with a higher permeability.

Because the DR73-4R7-R fixed inductor has a very low self-resonant frequency, it is capable of supporting the high-frequency signal with its low maximum equivalent series resistance for high frequency performance. It also offers high rated current, low DCR, high Voltage overload capability and Isolation Class F. The DR73-4R7-R fixed inductor is ideal for applications with large, complex DC/DC converters and power amplifiers.

The DR73-4R7-R fixed inductor is an ideal alternative for non-isolated flyback applications, as it offers low profile, cost-efficiency, and high frequency stability. The device is also suitable for direction open AC/DC applications in home audio and gaming consoles. Its high-frequency stability makes it perfect for high-end audio streaming applications.

In conclusion, the DR73-4R7-R fixed inductor is a versatile device suited for a variety of applications. The device can be used in automotive, home audio streaming, power distribution, EMI emission, and many more. It is highly reliable and has a wide set of working temperature range. Its high-frequency stability makes it perfect for high-end audio streaming applications.
