SRP1045-3R2M Application Field and Working Principle

Fixed inductors are electronic components used in DC-DC converters, electronic noise filters and other small frequency circuits, responsible for leaving input signals untouched while restraining high frequency electronic signals. Thrusting an electric current through a wire produces a magnetic field which, in turn, produces a new electrical current according to Faraday\'s law. Fixed inductors take advantage of this phenomenon, allowing conversion of electrical energy to a magnetic field and vice-versa.

The SRP1045-3R2M gives engineers a wide range of possibilities when designing DC-DC converters, noise filters or any other low-frequency circuit. As an example, this 3.2µH leaded inductor is composed of ferrite material which is ideal for high current design. Being ferrite-core, the SRP1045-3R2M offers high inductance in a small package, something particularly useful for small, limited space applications.

The SRP1045-3R2M has an inductance of 3.2µH with a current rating of 1.4A, saturation current of 2.2A, and an 0.11mH self-resonant frequency. It is suitable for data line/power line isolation and noise cancellation applications. It can also be used in combination with other inductors for power line filters or RF suppression applications. It is also compatible with lead-free soldering processes and with EMC testing requirements.

The working principle of the SRP1045-3R2M is simple and straightforward. When an electric current is introduced into the two terminals of the inductor, it creates a magnetic field according to Faraday’s law. This magnetic field in turn induces an electric current in the enclosed wire as well as in the surrounding area. When the current is removed from the inductor, the magnetic field collapses and induces another electric current which flows in the opposite direction of the original current.

The SRP1045-3R2M operates in the same way as other fixed inductors, by the same physical laws. The main difference is that it is designed with a ferrite core, providing a high inductance in a relatively small package. This makes it suitable for a wide range of applications, such as DC-DC converters, noise filters and RF suppression devices.

In conclusion, the SRP1045-3R2M is a relatively small and lightweight yet powerful ferrite-core fixed inductor. It has an inductance of 3.2µH, a current rating of 1.4A, a saturation current of 2.2A and an 0.11mH self-resonant frequency. It is suitable for a wide range of applications, including DC-DC converters, power line filters and noise cancellation devices. The SRP1045-3R2M works by inducing an electric current in the surrounding area when a current is introduced into the two terminals, allowing the conversion of electrical energy to a magnetic field and back.
