Fixed inductors are inductors that have a static inductance and are designed to be used in a variety of applications such as radio-frequency (RF) and power electronics. The SDR0906-4R7ML is a popular fixed inductor manufactured by Sumida that is designed for use in low frequency applications. The SDR0906-4R7ML is a small axial leaded inductor with an inductance of 4.7µH and a rated current of 0.73A. It is specifically designed for high temperature working conditions of up to +105°C. The SDR0906-4R7ML is also RoHS compliant and UL recognized.

The SDR0906-4R7ML is primarily employed in power electronics applications that require low frequency inductors. Due to its low inductance value and high current rating, it is often used in switching power supplies, DC/DC converters, and other applications that require low levels of energy. The small physical size of the SDR0906-4R7ML also makes it conducive to use in high density layouts, such as in cell phones or other handheld electronics. Its excellent thermal characteristics make it suitable for use in high temperature environments as well.

The working principle of a fixed inductor such as the SDR0906-4R7ML is based on the basic principle of electromagnetism. When an electrical current passes through the coil of wire in a fixed inductor, it creates an electromagnetic field around the wire. This field stores up energy as magnetic flux. When the current is stopped, the magnetic flux is quickly released, resulting in an induced current that passes in the opposite direction from the initial current.

The inductance of a fixed inductor is directly related to the geometry of its coil and the type of core that it employs. The SDR0906-4R7ML utilizes a ferrite core material, which contributes to its low inductance. The small size of the SDR0906-4R7ML helps to minimize the distance between the turns in the coil, which further reduces the inductance value. The low inductance value also helps to prevent energy loss due to the electromagnetic field leaking out of the device.

In addition to its inherent properties, the SDR0906-4R7ML contains a range of safety features that make it suitable for use in a variety of applications. These features include high radiation tolerance, low power absorption, and a large operating temperature range. Furthermore, the device can be easily integrated into various PCB layouts, and it is compatible with most soldering materials, allowing for easy installation.

Overall, the SDR0906-4R7ML is a versatile fixed inductor that is suitable for use in a variety of power electronics applications. It is largely employed in applications that require an inductor with a low inductance value and high current rating, as well as small size and excellent thermal dissipation capabilities. The device is also equipped with a range of safety features that makes it suitable for use in a wide variety of applications. Thanks to its impressive performance and features, the SDR0906-4R7ML is a popular choice for fixed inductor applications.
