Fixed inductors are passive electrical components that store energy through a magnetic field as electrical current passes through them. The magnetic field of the inductor opposes changes in current, creating a voltage drop across the inductor. Fixed inductors are available in various shapes and sizes and have different applications depending on the type of inductor. One type of fixed inductor is the SDR0602-221KL. This article will discuss its application field and working principle.

The SDR0602-221KL is a surface mount ferrite bead inductor designed for use in wide range of applications. This inductor is suitable for high current and high frequency applications such as Switch Mode Power Supplies (SMPS), USB devices, mobile phone data cards, and notebooks. Its small 0.6mm footprint makes it ideal for applications where space is restricted. This inductor is also suitable for automotive applications and is rated for up to 200mA of continuous current.

The SDR0602-221KL consists of a highly permeable ferrite core material and an insulated copper winding. The core provides a medium for the magnetic field to flow through, while the windings provide the resistance to create a voltage drop. The copper winding is insulated to prevent short circuits caused by heat or vibrations. The inductance of this particular inductor is 0.22μH (micro Henries), with a DC resistance of 0.01ohm. This inductor has a maximum working temperature of 125°C and a minimum working temperature of -40°C.

The working principle of the SDR0602-221KL is based on the concept of Inductive Reactance. When a current is passed through the inductor, a magnetic field is created and the voltage drop across the inductor increases as the current increases. This increase in voltage is known as inductive reactance and is measured in Ohms. As the frequency of the current increases, the inductive reactance also increases and the voltage drop across the inductor increases accordingly. In addition, the inductance of the inductor also affects the voltage drop.

The SDR0602-221KL is a versatile inductor that is suitable for a wide range of applications. Its low profile and compact size make it ideal for high frequency and high current applications in automotive electronics and other electronic devices. Its inductance and DC resistance make it suitable for a variety of different circuit designs and make it a great choice for power supplies, USB devices, and other electronic applications.
