Fixed inductors, also called choke coils, are inductors with a wide range of applications in circuit designs. The SRP1055-4R5M is a type of surface mount fixed inductor, designed for high-frequency power transmission in advanced consumer electronics and telecommunications.

The SRP1055-4R5M inductor is composed of a core, or electromagnetic material, that reacts to a change in electric current, inducing a voltage within an electric circuit, and a winding, made of copper or aluminum foil, which acts as a signal loop. The SRP1055-4R5M is available with a high saturation magnetic flux density of up to 2.5 Tesla, and an inductance range of 0.47μH-1.0μH.

The SRP1055-4R5M inductor is designed for use in high-frequency RF and power applications, including cellular and GPS phones, Bluetooth, Wireless LANs, wireless communication systems, and satellite TV receivers. It provides minimal signal distortion, excellent thermal stability, and high efficiency. The SRP1055-4R5M is also designed to reduce noise and provide excellent shielding for critical audio and RF circuits.

The SRP1055-4R5M inductor’s working principle is based on the transformer effect, which states that a change of electric current in one circuit results in a proportional voltage in the same or related circuit. This is attained through electromagnetic induction. When an electric current passes through a coil of wire, it produces a magnetic field that then produces a voltage in a second form. The SRP1055-4R5M utilizes this phenomenon to help transmit signals over long distances with minimal distortion.

The SRP1055-4R5M has an extended temperature range between -40°C and +85°C, which allows the inductor to be used for mobile, extreme temperature applications. It also has a low DC resistance of 0.037 Ohms, enabling the SRP1055-4R5M to act as an efficient current filter. In addition, the SRP1055-4R5M is highly reliable, with a high surge current rated up to 3 A. This helps the inductor handle high peak currents without being damaged.

The SRP1055-4R5M inductor is a widely used fixed inductor for high frequency RF and power applications. Due to its high performance features, such as low DC resistance, extended temperature range, high saturation magnetic flux density, and surge current rated up to 3 A, the SRP1055-4R5M is a reliable and efficient inductor suitable for a wide range of applications.
