Fixed inductors are components used to create electric circuits, utilizing static magnetic fields to store and control and transfer electric energy. Inductors come in an array of different sizes and shapes, each with a particular capacity and an intended use for the electric circuits they are used to construct. 3090-271F is one such inductor, a fixed inductor, produced by Unisonic Technologies Co. Ltd., a leader in the telecom field in Taiwan. In this article, we will discuss the application field and working principle of 3090-271F.

Application Field

3090-271F is designed for use in power management applications. This inductor can sustain high temperatures of up to 125°C with minimal effect on characteristics. With a high peak current of up to 50A and low DCR, this inductor makes an ideal solution for use in various power management DC/DC converters and other similar applications. Additionally, this inductor has a high power efficiency of up to 95%.

This device is also suitable for TV, digital cameras, video game consoles, and other electronic devices that require power management integrated circuits (PMICs). Its small size, low height, and relatively low cost makes it ideal for deploying in mass production. In these applications, the 3090-271F is used to create filters and eliminate EMI (electromagnetic interference) and RFI (radio frequency interference).

Working Principle

The 3090-271F is a molded power inductor that utilizes principle of self-inductance to store and control electric energy. Self-inductance is a phenomenon where an electromagnetic field is produced when electricity passes through a conductor. This field then induces a counter EMF (electromotive force) that opposes the initial current, and this opposition can be used to regulate the current. In others words, the inductor utilizes inductance to control and restrict the flow of electric current in a circuit.

In the case of the 3090-271F, this device is designed for use in power management applications. It utilizes its high peak current of up to 50A and low DCR (direct current resistance) as well as its high power efficiency of up to 95%. The inductor creates an electromagnetic field that affects the flow of electric current. This is done through the phenomenon of self-inductance, which induces counter-EMF to oppose the initial current.

This controllable current allows the inductor to be used in power management applications in many different ways. The device can be used to create filters and eliminate EMI (electromagnetic interference) and RFI (radio frequency interference). It can also be used to regulate the flow of current in a circuit, and it is this phenomenon which allows it to be used in power management applications.

Conclusion

Fixed inductors such as the 3090-271F can be used in many different power management applications, with many advantages. The device is small and low cost, with a high peak current of up to 50A and low DCR as well as a high power efficiency of up to 95%. Additionally, the device utilizes the principle of self-inductance to regulate the flow of electric current in order to create filters and eliminate EMI and RFI. As such, the 3090-271F is an ideal fixed inductor for use in many power management applications.
