Fixed Inductors

Fixed inductors, also known as choke coils, are used for a variety of power supply applications. There are many types of fixed inductors, such as cylindrical ferrite core inductors, ferrite bead inductors, and planar transformers. In this article, we will focus on a specific type of fixed inductor, the IM04SH180J.The IM04SH180J is an IC-compatible surface mountable fixed inductor designed for telecommunications applications. It measures 6.4mm x 5.6mm and has a maximum operating frequency of 1.8GHz. The inductance is 4.7nH. This inductor is ideal for use in Wi-Fi or LTE applications, as well as RF and microwave filter circuits. The IM04SH180J has a low DC resistance, low inductance tolerance, and low profile. The inductance is very stable over a wide range of temperatures, from -40°C to +105°C. This is important for telecom and wireless applications, as stability is essential for precise operation. The inductance tolerance is specified as ±10%, ensuring that tight circuit performance specifications can be met. The low profile of the inductor allows for easy integration into space-constrained designs.The working principle of the IM04SH180J is based on a reaction between the current flowing in the coil and the magnetic field of the core material. As the current increases, the magnetic field generated by the coil increases in strength, storing energy in the form of magnetic energy. This energy is released in the form of an EMF when the current decreases. Thus, the inductance can be calculated according to electromagnetic principles. The inductance of the IM04SH180J is specified as 4.7nH, allowing designers to easily calculate the EMF based on the current.In summary, the IM04SH180J is an IC-compatible, surface mountable fixed inductor designed for telecommunications applications. It has a low profile, low DC resistance, and low inductance tolerance, making it ideal for a range of circuit designs. The working principle of this inductor is based on a reaction between the current flowing in the coil and the magnetic field of the core material, allowing designers to calculate the inductance based on electromagnetic principles.
