Fixed inductors are a type of electronic component which serves the purpose of storing energy in the form of a magnetic field. The 4470R-31F is a high current, low profile fixed inductor with a surface mount footprint suitable for reflow soldering.

The 4470R-31F has a low DCR (direct current resistance) and a high saturation current for maximum efficiency in a variety of applications. It also has an operating frequency up to 1 MHz and can withstand a surge current up to 32A. This makes it ideal for use in DC/DC converters, switching regulators, and high-speed switching circuits in computer peripherals, wireless, and portable devices.

Due to its high current carrying capacity, the 4470R-31F is also suitable for a variety of charging and high-current applications, including smartphones, tablet chargers, and automotive circuits. Additionally, its low profile design makes it well-suited for mounting on tight boards, which helps to reduce the space needed for design.

The main working principle of the 4470R-31F is to create a magnetic field when a current is applied to it. This magnetic field stores energy in the form of a varying current, which is then released when the current is withdrawn. The inductor then passes on the energy to the components downstream.

As the current flowing through the inductor varies, there is a change in the magnetic field which causes a voltage drop across the inductor, referred to as Voltage Spikes. These surges of voltage can be very damaging to electronic components, and the 4470R-31F effectively protects these components as it absorbs the spikes before they can affect the other elements.

The 4470R-31F also features a high temperature resistance, enabling it to be used in demanding applications where heat is a factor. Additionally, its high insulation resistance and low leakage current ensures superior performance in high current applications.

In summary, the 4470R-31F is an ideal fixed inductor for a range of applications, including charging equipment, computer peripherals, power supplies, and automotive circuits. Its low-profile design and high current capacity make it ideal for tight boards, and its high temperature resistance and low voltage spikes ensure reliable performance.
