Fixed inductors are widely used in a variety of electronic circuit design for handling and filtering signals. Inductors add impedance to a circuit and cause a delay of current flow. Inductors can be used as part of an oscillator or a tuned circuit, as well as to “choke” off higher frequency signals. Applications for fixed inductors are found in a host of products, including TV sets, laptops, and cell phones.One type of fixed inductor is the IR04SH101K. These inductors are self-shielded, with double-sided ferrite core construction. The general purpose grounding of the ferrite core provides excellent high frequency performance. The inductance of the IR04SH101K is 10µH and the resistance is 50mΩ (ohm). The circuit design for the IR04SH101K features a low DC resistance and high inductance capability. The inductors are rated at 0.35A and 65°C with a maximum operating temperature of up to +125°C. The inductors also feature a radial leaded version for soldering to the board and an axial leaded version for through hole mounting.The IR04SH101K is well suited for various applications including:

• RF circuits – provides high Q characteristics.
• High frequency communications – the self-shielded property of the inductors reduces noise and distortion.
• Line filters – used for eliminating unwanted noise frequencies in power supplies.
• Timer circuits – improves response time.
• Switching power supplies – filters out high frequencies and helps reduce losses.

The IR04SH101K also has a small form factor and low weight. This makes it a great choice for space-constrained designs and high density boards.The working principles of the IR04SH101K are often categorized by its type of magnetic structure and its inductance value. The ferrite construction gives the IR04SH101K a high permeability ( inductance ) and low reluctance ( resistance ) which allows for good efficiency in power transmission. The inductance value of the IR04SH101K is determined by the number of turns in the winding and the inductor’s core material.The IR04SH101K utilizes a high quality ferrite core which has a high magnetic saturation as well as a high flux saturation. This allows for a high quality inductor that is very efficient and stable. It also allows the IR04SH101K to use fewer turns and maintain the same inductance value with lower losses which leads to better efficiency and lower thermal heating.The inductance of the IR04SH101K is controlled by the number of turns in the winding, the core material, and the air-gap in the core. When current flows through these components, the inductance value changes according to Faraday’s Law of Induction which states that when an electric current flows through a conductor, a magnetic field is created. This magnetic field stores energy which causes an inductive interference in the circuit which is the basis of the inductor’s function.The IR04SH101K is a great value for electronic applications such as RF circuits, High frequency communications, Line Filters, Timer Circuits, and Switching Power Supplies. The combination of its high inductance, small form factor, and low weight make it ideal for space-constrained designs and high density boards. Its high permeability, low reluctance, and Faraday’s Law of Induction also result in high performance with low losses and high efficiency.
