Fixed inductors are electronic components designed to store electrical energy in a magnetic field. They are used to control the current in an electrical circuit and to block signal noise. 103-221HS inductors are a type of non-Potted inductor, specifically designed for board level high current Switching applications. With their low current rating, they are ideal for applications such as power supplies, motherboard designs, High Frequency Switched-Mode Power Supplies (SMPS) and other low voltage use.

The 103-221HS inductor consists of an iron-core material magnetically shielded by two air gaps of different depths on either side. The air gap provides an increase in the inductance which helps to lower the total circuit current. The magnetically shielded design also helps to reduce EMIs (electromagnetic interference) coming from the inductor when it\'s used in high voltage or high current systems.

The 103-221HS can handle up to 6A of constant current with an inductance value of 1.83μH, making it suitable for most applications. It also has a DCR rating of 15mΩ, ensuring efficient power management for high current switching. The operating temperature range for this component is from -25℃ to +85℃. The surge current rating can handle a peak current of up to 30A for a short duration with a very low temperature rise.

The 103-221HS inductor works on the principle of Farady’s Law of induction. This law states that when a changing current flows through a coil, a magnetic field is generated around the coil. This magnetic field then induces an EMF in the coil. The frequency of this EMF is equal to the frequency of the changing current. This EMF then acts on the core material and reduces the magnetization of the core. The resulting decrease in magnetization causes a decrease in the power consumed.

The 103-221HS inductor is easy to install due to its small size and simple construction. It is important to ensure that when integrating this inductor into a circuit, the proper values of voltage and current are specified to avoid unwanted effects. The 103-221HS is an excellent choice for applications requiring a high current inductor due to its low resistance rating and high-temperature range. This makes it an ideal component for designs requiring high current switching, power supplies, or other board level applications.
