Fixed inductors are extremely versatile and can be found in a multitude of electronic devices ranging from simple radios to complex microcontrollers. The SDR2207-4R7ML is one type of fixed inductor, and it is commonly used for more power-intensive applications, such as in power supplies and motor drives. This article will discuss the application field and the working principle of the SDR2207-4R7ML.

Application Field

The SDR2207-4R7ML is a radial-leaded, fixed inductor. It is made of a metalized polyester film, and is rated to support up to 100 volts. It has a very low DC resistance of 0.037 ohms, and a rated current of 4.7A. The inductance of the SDR2207-4R7ML is 4.7μH, and the total height of the component is 12.2mm. The SDR2207-4R7ML is commonly used in power supplies, motor drives, and other circuits that require more power.

Working Principle

An inductor works by creating a magnetic field through the coils of wire within itself when an electric current is applied. This magnetic field then reacts against the electric current, creating a back EMF (electromotive force). This back EMF opposes the current, effectively slowing down the current flow - this is known as inductance. The magnitude of the inductance of the SDR2207-4R7ML is determined by the number of coils in the wire, the length of each coil, and the core material the wire is wound around.

The back EMF created by an inductor is used in a variety of ways, such as storing energy, limiting current flow, and filtering out unwanted frequencies. In a power supply, an inductor can be used to regulate the current flow, filtering out any unwanted current peaks or spikes that could potentially damage the other components. In a motor drive, an inductor can be used to store energy in the form of a magnetic field, making the motor start and stop more smoothly.

In addition to its uses in power supplies and motor drives, the SDR2207-4R7ML can also be used in circuits requiring more power, such as in amplifiers, LED drivers, and voltage converters. Its high power handling capacity, low DC resistance, and small size make it an ideal choice for a variety of power-intensive applications.

The SDR2207-4R7ML fixed inductor is an excellent choice for a variety of power-intensive applications, such as power supplies, motor drives, amplifiers, LED drivers, and voltage converters. Its high power handling capacity, low DC resistance, and small size make it an ideal choice for these applications, and its magnetic field-based working principle makes it reliable and efficient in its use.
