Fixed inductors are electric components that store energy in the form of a magnetic field through the process of induction. The MS90538-7ST is a fixed inductor typically used in applications such as power supplies, DC/DC converters, and motor drivers.

The MS90538-7ST fixed inductor is packaged in an encapsulated coil assembly enclosed in epoxy to protect against vibration and heat. The inductance value is indicated by its series number, and range from 0.22 to 390 microhenrys. It also has an operating temperature range of -55°C to +125°C, which makes it well-suited for use in harsh environments.

The working principle of the MS90538-7ST is based on the law of induction, first proposed by Michael Faraday in 1831. When current passes through the inductor, it creates a magnetic field. This magnetic field induces a voltage in the inductor that is proportional to the rate of change of current through the inductor. In other words, the heavier the load, the greater the voltage across the inductor.

The inductor is also designed for distributed capacitance since it features an internal capacitor that creates an impedance that limits the amount of current that can pass through the inductor. This distributed capacitance feature is essential when the system requires a high degree of control over the current. It prevents the inductor from becoming saturated at low frequencies and maintains an even and low voltage across the inductor at all frequencies.

The MS90538-7ST fixed inductor also features a ferrite core that provides the physical stability and helps reduce electromagnetic interference in the system. Additionally, the ferrite core reduces the temperature coefficient of the inductor to maintain a consistent value.

Overall, the MS90538-7ST fixed inductor is suitable for applications where current control is desired, such as in power supplies and DC/DC converters. It is also suitable for use in harsh environments due to its wide operating temperature range and its ferrite core that helps reduce EMI levels in the system.
