Fixed inductors are a type of component that are designed to provide steady current paths within an electric circuit. They are used in a wide range of applications, such as power supplies, communication systems, and automotive electronics. Specifically, the SP1210R-332K fixed inductor is designed for use in power circuits where high power output is needed in a compact size.

SP1210R-332K Application Field

The SP1210R-332K is a power type, SMD fixed inductor, and it is characterized by a 2.2mH nomial inductance, 4.6A saturation current, and 330mΩ series resistance. It has a 1210 size with a maximum height of just 3.2mm, making it an ideal solution for high capacity, low-profile applications. The power rating is rated at 11.3W, making it suitable for use in high power applications.
The primary application for the SP1210R-332K is in automotive electronics. It has been designed to be used in the powertrain, transmission, airbag, and comfort systems, as well as in engine and starter systems. It is also suitable for use in DC-DC converters, power supplies, amplifiers, transceivers, and other high-power applications.

SP1210R-332K Working Principle

The working principle of the SP1210R-332K fixed inductor is based on the principle of electromagnetic induction. An electric current is passed through a coil of wire, creating a magnetic field. The magnetic field induces a current in an adjacent coil, which is then directed back into the main coil. This creates a closed loop, in which energy is transferred from the primary coil to the secondary coil. This energy transfer is known as inductance.

The SP1210R-332K fixed inductor uses this principle to provide a steady current in a power circuit. Its low profile design and high power rating make it an effective solution for automotive electronics and other high-power applications.

The SP1210R-332K has a nominal inductance of 2.2mH, meaning that the current will remain steady even when the load varies. It also has a series resistance of 330mΩ, so the voltage drop across the component will remain low. The 4.6A saturation current limit ensures that the inductor will not be damaged by overloading.

In summary, the SP1210R-332K fixed inductor is an exceptionally compact solution for high-power applications in the automotive and other industries. Its working principle is based on electromagnetic induction, allowing it to provide a steady current path even when the load changes.
