IR04SH180K

Fixed inductors are electronic components that store energy and allow for the flow of electric current in a circuit. In particular, they provide an inductance that is fixed, or does not change with time. A fixed inductor is the most basic form of an inductor, with the design based on basic rules of electro-magnetism. The IR04SH180K is an example of a fixed inductor, used for a variety of applications and with a specific set of specifications and working principles.

Application Fields

The IR04SH180K can be used in a variety of application fields, particularly those requiring fixed-inductance properties. Examples of these include automotive, consumer and industrial applications; mobile phones; LED lighting control systems; portable radios; and power converters. In addition, this fixed inductor is particularly designed to be tolerant of high voltages and provide high shielding permeability and stability. Applications that require high levels of interference suppression and EMI shielding will particularly benefit from using the IR04SH180K.

Specifications

The IR04SH180K has a number of specific specifications and operational requirements that must be considered before use. Its inductance ranges from 10 to 180 microhenries, while its rated current ranges from 0.2 to 2.3Amps. It also has a DC resistance ranging from 0.40 to 6.2 ohms, as well as a DC saturation current between 0.2 and 2.3 Amps. The allowable rated current has a direct effect on the IR04SH180K’s temperature rise and inductance value, so it should be taken into account. Moreover, the operating temperature range for this fixed inductor lies between -40 and 80 degrees Celsius.

Working Principles

The working principles of the fixed inductor IR04SH180K is based on the principle of changing energy from electrical to magnetic form. The fixed inductor works by increasing and decreasing the current through its coil in a controlled manner, converting electrical energy to magnetic energy then back to electrical energy. This is achieved by a coil consisting of wire and a core that continuously alternates the current in a loop. The voltage across the fixed inductor is the product of the inductance and the rate of change in current.

The IR04SH180K uses a ferrite core material with high permeability, which helps to reduce the effects of eddy currents and iron losses. It also offers excellent suppression performance at high frequencies, offering high performance stability under high temperature conditions. As a result, the IR04SH180K is well-suited for applications in high frequency power supplies and LED lighting control systems.

Conclusion

The IR04SH180K is a type of fixed inductor used in a range of applications. It has specific specifications, with an inductance ranging from 10 to 180 microhenries, as well as a rated current from 0.2 to 2.3Amps. Its working principles rely on a changing current through the coil, which converts electrical to magnetic then back to electrical energy. The IR04SH180K also benefitted from a ferrite core material and high permeability, offering excellent suppression performance and stability at a wide range of temperatures.
