Fixed inductors, or inductors in general, are passive electronic components used in circuits primarily to provide inductance. The MS75084-7ST is one type of fixed inductor from Molex, a worldwide electronic manufacturer. It is an automated assembly SMD inductor with a fixed value of 470nH and a maximum current value of 1.6A. This inductor can function across a temperature range of -40 to 85°C. In terms of physical dimensions, the MS75084-7ST is a 7.2mm x 7.2mm x 5.84mm component, making it well-suited for several applications.

The first application field for the MS75084-7ST is in voltage regulators and power supplies. Voltage regulators are used to deliver a consistent voltage level regardless of what the current demands are. The MS75084-7ST can be used as a part of the filter circuit, providing low pass filtering that discriminates against high frequency noise. Since the MS75084-7ST operates over a wide frequency range, it is suitable for these applications.

The second field of application for the MS75084-7ST is within LED lighting systems. The rapid pulse of current created by LEDs can create harmonic noise in the circuit. By using an inductor such as the MS75084-7ST, this harmonic noise can be eliminated and the performance of the LED system improved. Additionally, this inductor can also be used to create a flicker free light which is typically desired in LED applications.

Besides its two main applications, the MS75084-7ST can also be used in other electronic circuits such as SMPS, DC/DC Converters, Switching Mode Power Supplies, Audio Applications, RFID Tags, and Cellular Communications Equipment. All these applications benefit from the low DCR and low resistance nature of the MS75084-7ST which helps reduce power losses and improve circuit performance.

The MS75084-7ST is capable of working across an operating frequency range of up to 1.0MHz. As the current through the device increases, so does the inductance of the part. This is due to the fact that the MS75084-7ST is a ferrite-base chip inductor, meaning it uses a ferromagnetic material as its core. Meaning when the magnetic field of the MS75084-7ST is increased the inductance also increases.

The MS75084-7ST also features a high saturation current which allows it to work in high power applications without experiencing too much heat or performance degradation. This means that the MS75084-7ST can handle large amounts of current without deteriorating. This makes it well suited to work in power converters and similar applications.

All in all, the MS75084-7ST from Molex is a very useful fixed inductor. With its 470nH of inductance, wide operating frequency range of up to 1.0MHz, high saturation current, and low DCR it makes for an excellent choice for several applications. It is suitable for use in LED lighting systems, voltage regulators, power converters, and RFID tags. The MS75084-7ST is an all-rounder inductor with a variety of uses and is sure to last for a long time.
