Fixed inductors are electronic components that can store energy and create a magnetic field in an electric circuit. This magnetic field allows a current to flow through the inductor, thus creating an electrical connection between two electrical points. Commonly used in computers, audio systems, and other electronic equipment, fixed inductors are a key component in electrical engineering and other industries. The SRN4012TA-4R7M is a type of fixed inductor that has several important applications and a distinct working principle.

The SRN4012TA-4R7M is a rectangular surface mount inductor. Measuring 5.1mmx3.0mmx2.2mm, it has a maximum inductance of 4.7uH and is rated at dc 70mAx12A (25MHz). Its unique design makes it suitable for high-density, surface-mount circuits. This inductor is made from a ferrite core with paramagnetic material wound around it. It is ideal for applications such as dc-dc converters, circuit filters, antennas, and signal conditioners.

The working principle of the SRN4012TA-4R7M is based on the same principles that apply to all inductors. An electric current creates a magnetic field, which induces a back-electromotive force (EMF), which in turn acts to oppose any changes in the current. Thus, when the current flowing through the inductor is changed, the magnetic field and back-emf change in a manner designed to maintain the original current. This opposition to change is known as inductance.

In the SRN4012TA-4R7M, the inductance is achieved by a coil of paramagnetic material wound around a ferrite core. The core helps to concentrate the magnetic field, while the coil ensures that the current creates an even field of magnetic flux around the inductor. The inductance created by the SRN4012TA-4R7M is rated at 4.7uH, which is suitable for high-frequency circuits and applications.

The SRN4012TA-4R7M is a versatile fixed inductor with a range of applications. As previously mentioned, this type of inductor is often used in dc-dc converters and circuit filters. It can also be used in antennas, signal conditioners, choppers, bias networks, and power supplies. Additionally, it is well-suited for use in audio circuits such as crossover networks, low-pass filters, equalizers, and other audio applications.

In summary, the SRN4012TA-4R7M is a type of fixed inductor that is used in an array of electronic circuits and applications. It measures 5.1mmx3.0mmx2.2mm and is rated at 4.7uH, allowing it to be used in applications requiring high-frequency operation. As a surface mount inductor, it is well-suited for high-density circuits such as dc-dc converters, circuit filters, signal conditioners, and audio circuits.
