Fixed inductors are electronic components used to perform a variety of power filtering, energy storage, and AC/DC voltage conversion tasks in electrical circuits. Among them, the 4470R-09G is a popular inductor device that delivers high reliability and performance.

The 4470R-09G comes in a cylindrical, ribbon-like structure with a 0.8 mm height profile and a single-line marking for ease of installation. It features an extended working temperature range between -40°C to +85°C and advantages such as reflow-able solderability and low RF noise, which makes it suitable for use in highly sensitive devices, such as cellular phones, digital set-top boxes, and wireless routers.

The 4470R-09G is a useful inductor for applications ranging from low-power RF to high-performance electric circuits. It is widely used in switching power supplies (SMPS), motor drives, and audio, video, and computer-related applications. In addition, its high current capacity and low leakage make it an ideal solution for current-limiting circuits and other noise suppression applications.

The 4470R-09G’s working principle is based on the Faraday’s law of induction. It consists of a single-layer or multiple parallel-connected windings of soft magnetic material, such as magnet wire or powder cores, wrapped around a magnetic core. When electrical current flows through the windings, a magnetic field is created, which induces voltage in the windings and which creates a back-EMF, or a change in magnetic flux.

This back EMF is a basic form of electrical energy storage, which can then be used in a variety of applications. For example, the 4470R-09G can be used in switching regulators, where it acts as an energy storage device and helps reduce switching losses, as well as in power factor correction and load balancing. The device is also a great choice for 6- and 8-phase power designs, where ultra-low inductance values are required.

In summary, the 4470R-09G is a high-performance, reliable, and cost-effective inductor device suitable for a wide range of electronic applications. Its features and working principles make it an ideal choice for applications such as power supply filtering, current-limiting, and power factor correction.
