Fixed inductors are electrical components that store electrical energy in the form of a magnetic field. The SD20-220-R is a model of a fixed inductor, which has a wide range of applications in various different industries. This article will discuss the application field and working principle of the SD20-220-R fixed inductor.

The SD20-220-R is a high-quality, high-performance inductor. It is typically used in DC-DC converters, such as buck, boost and buck-boost converters. In addition, it can be used in portable and battery-operated electronic systems, motor control equipment, and air conditioning and heat pump systems. Furthermore, it is capable of coping with very high power ratings, making it a popular choice for surge currents and high-peak power applications.

The SD20-220-R has a core material made from ferrite for high reliability and low power losses. It is also able to operate in a temperature range of -40℃ to +125℃, and has an insulation resistance of ≥100mΩ. Moreover, it has an excellent saturation current, making it suitable for high-current applications. In addition, its size allows for space-saving mounts and an easy and efficient installation.

In terms of its operating principle, the SD20-220-R contains a ferrite core wound with copper wire. An alternating current is then applied to the inductor, which causes a magnetic field to be generated in the core. This magnetic field generates a back-emf (electromotive force), which opposes the system voltage, and reduces the current flow through the inductor. This effect is called inductance, and it enables the inductor to “smooth out” the current flow from the power supply.

The SD20-220-R fixed inductor is a versatile and reliable component due to its wide range of applications, high-performance ratings, and excellent inductance capabilities. It enables the smooth regulation of current flow from a source, and is suitable for applications in a variety of industries.
