Fixed inductors, such as the SRU3017-3R3Y, are passive components used to store energy in a magnetic field. Inductors are used to regulate current and electrical signals in a variety of applications, including audio frequency noise suppression, power supply filtering, and radio frequency tuning. In this article, we will discuss the application field and working principle of the SRU3017-3R3Y.

The SRU3017-3R3Y fixed inductor is an SMD, ferrite-based inductor designed for use in impedance matching and EMI suppression applications. It is a shielded inductor, which is why it is suitable for EMI suppression. Ergonomically, its small size and low weight make installation and maintenance convenient compared to other types of inductors. This inductor has a wide operating temperature range of -40°C to +85°C, making it suitable for automotive electronics and communications equipment applications.

The SRU3017-3R3Y offers excellent low-resistance characteristics, which makes it a suitable choice for high-frequency filtering applications. In specific, this inductor can be used in combination with capacitors for impedance matching, high-frequency noise suppression, and transformerless regulated power supplies. Furthermore, this inductor exhibits excellent EMI suppression characteristics and can be used in radio frequency tuning and high-sensitivity circuit designs.

In terms of its working principle, the SRU3017-3R3Y is based on Faraday’s law of induction. This law states that when a conductor moves through a magnetic field, it will induce an electromotive force (EMF). The SRU3017-3R3Y features a ferrite core, which stores energy in a magnetic field and then undergoes induction of electrical current. When electrical current passes through it, the magnetic field will also be reversed and will induce an EMF in the opposite direction, thereby suppressing noise in the circuit.

In conclusion, fixed inductors such as the SRU3017-3R3Y are excellent components for impedance matching, EMI suppression, and radio frequency tuning applications. In these types of applications, the SRU3017-3R3Y features a low-resistance characteristic and excellent EMI suppression capabilities. Furthermore, the working principle of this inductor is based on Faraday’s law of induction. As this inductor is highly compact and lightweight, it is suitable for automotive electronics, communications equipment, and numerous other applications.
