The MPI4040R3-1R5-R also has excellent temperature stability, low ESR, and high surge current capabilities.

The working principle of the MPI4040R3-1R5-R fixed inductor is based on Faraday’s law of induction. This law states that when an electric current is applied to a wire, it will create a magnetic field around it. This magnetic field creates a force on the wire, causing it to oscillate. This oscillation creates a counter-electrical field, which in turn produces a voltage across the inductor. This is known as inductance, and it is a measure of how much energy the inductor can store in its electromagnetic field. The inductance of the MPI4040R3-1R5-R has been designed to give the desired performance in many applications.

The MPI4040R3-1R5-R is a reliable and cost-effective solution to many common low-power power supply applications. It is packaged in an ultra-compact 5x5x3mm package for ease of installation and can handle temperatures from -40 to +85 Celsius and is RoHS compliant. Its excellent performance and low profile guarantee that the MPI4040R3-1R5-R is a suitable solution for many electronics installations.
