Fixed InductorsFixed inductors, or inductors, are components that store energy in their magnetic field as an electrical current passes through. They are used to filter radio-frequency signals and powerline noise, and provide control of electrical power. The MPI4040R2-3R3-R is a fixed inductor from the MPI series by Max Power. It has a wide range of uses and is ideal for many short-circuit-current-reducing inductor applications.The MPI4040R2-3R3-R is composed of a high-purity magnetic core constructed from a ferrite compound. This ferrite compound is very effective at controlling short circuit current and controlling peak inrush current while providing high saturation current capability and low DCR. The external enclosure is plastic and is designed to protect the core from harsh environmental conditions.The inductor is rated at 40 A with a DC current range of 4.3 to 40 A. It can handle a minimum of 40 V and a maximum of 100 V. With a resistance rated at 3.3 mΩ it allows for excellent power dissipation and greater current range while keeping low radiation characteristics. The inductor is designed to provide a very low inductance of 0.4 mH thus lowering the impedance of the device and providing improved frequency response.The working principle of the MPI4040R2-3R3-R is based on Faraday’s law of induction. Faraday’s law of induction states that when a current-carrying conductor is placed in a varying magnetic field, an electric potential is generated across the conductor. The electric potential is proportional to the rate of change of the magnetic field. This effect is used in the MPI4040R2-3R3-R to control short-circuit-current-reducing inductor applications.The application fields of the MPI4040R2-3R3-R include motor control systems, leakage protection, pulse modules, switching power supplies, controllers, over-voltage protection, frequency changers, voltage boosters, etc. Other areas of application are battery management systems, DC/DC converters, welding systems, inverters, alarms, voltage regulators, power supplies, and solar power systems.The MPI4040R2-3R3-R is ideal for many applications and is an effective way to control peak inrush current, reduce noise, and provide reliable electrical power. With its wide current range, high saturation capability, and low DCR the MPI4040R2-3R3-R is an excellent choice for short-circuit-current-reducing inductors. The high-purity magnetic core and plastic enclosure, designed to protect the core from hazardous environmental conditions, make the MPI4040R2-3R3-R an ideal choice for a range of industrial applications.
