Fixed Inductors are electrical components that store energy in magnetic fields when electric current is applied in a coil. They generally consist of a core material, such as ferrite or iron, and conductors, such as copper wire. Common applications of fixed inductors include filter circuits, transmitting / receiving filters, transformers, pattern RF (Radio Frequency) ID systems, and high frequency antennas.

MS90538-10RU is a fixed inductor developed by Murata Manufacturing Co. Ltd. Its main feature is “filled chemical valve treatment”, which is a filling process of valve-oriented chemicals for the wire. This filling features creates an increased hole rate and improves electrical characteristics on the interior of the wire, thus allowing higher inductance, good solderability, and superior heat dissipation within a compact, light-weight design.

MS90538-10RU’s main application fields are miniaturized high-frequency DC-DC converters and antennas. In miniaturized high-frequency DC-DC converters, its high heat dissipation capability enables different voltages to be outputted more efficiently. As for antennas, the improved electrical characteristics allow antennas to operate more reliably and reduce overall size.

MS90538-10RU’s working principle is based on the Coil Law. According to the Coil Law, the inductance of an inductor is proportional to its geometry, the relative permeability of its core material, and the number of its windings. In the case of MS90538-10RU, its core material is ferrite (manganese-zinc ferrite or iron powder core) and has 8 windings. By manipulating its geometry, number of windings, and core material, its electrical characteristics (inductance, Q value, and temperature characteristics) can be adjusted to meet different needs.

In addition, the parameters and characteristics of MS90538-10RU can be optimized by its filling process. The improved hole rate within the wire enables higher inductance and superior thermal characteristics within a compact, light-weight design. Thus, MS90538-10RU is the ideal inductor for miniaturized high-frequency DC-DC converters and antennas.
