MPI4040R3-1R2-R Fixed Inductors: Application Field and Working Principle

Fixed inductors are essential components in a variety of electronics. They are used in products such as cellular phones, TVs, radios, and computers to store energy and regulate current. The MPI4040R3-1R2-R is a popular fixed inductor developed by Murata Electronics. This article will discuss the application field and working principle of the MPI4040R3-1R2-R.

The MPI4040R3-1R2-R is a high frequency, surface mount, power inductor. It has a Kool Mu® core, and is manufactured with RoHS compliant wire. The component achieves a low DC resistance and high current capacity. It is suitable for applications in a wide range of power supply designs.

Due to its low resistance and high current capacity, the MPI4040R3-1R2-R is suitable for use in battery powered devices, such as laptops, cell phones, and medical equipment. It is also suitable for use in switched-mode power supplies, voltage regulator modules (VRMs), and other power applications. The component is ideal for products that require low-noise operation, such as DSL modems, cable modems, and digital audio amplifiers.

The MPI4040R3-1R2-R has a low DC resistance rating of 0.2mΩ with a rated current of 40A. This rating is much lower than similar inductors, and it enables the component to store and regulate current with higher efficiency. The component has an internal shield to protect against radiated emissions, making it ideal for use in products requiring low-noise operation.

The MPI4040R3-1R2-R is designed to operate at temperatures ranging from -55°C to +125°C. This wide operating temperature range makes it suitable for use in a variety of environments and products. The component also has a high inductance rating of 4.2mH, which makes it suitable for use in products operating at high frequencies.

At the core of the MPI4040R3-1R2-R is a Kool Mu® core, which is composed of two layers of nanocrystalline nickel-zinc ferrite. The nanocrystalline structure increases the material\'s magnetic permeability, which allows the component to store more energy than traditional ferrite cores. This enables the component to operate with higher efficiency, which is necessary for low-noise operation.

The working principle of the MPI4040R3-1R2-R is based on Faraday\'s law of induction. This law states that a changing magnetic field will induce a current in a conductor. In the case of the MPI4040R3-1R2-R, an electrical current flows through the coil, which generates a magnetic field. This magnetic field then induces a current in the core of the component, which is then stored in the component\'s magnetic material. When the electrical current is removed, the magnetic field collapses, inducing a current in the opposite direction.

The MPI4040R3-1R2-R is an excellent choice for a variety of applications, ranging from battery operated devices to high frequency applications. Its low resistance and high current capacity make it ideal for low-noise operation, and its high inductance rating makes it suitable for use in high frequency applications. The Kool Mu® core increases the component\'s magnetic permeability, making it highly efficient and capable of storing more energy than traditional ferrite cores.
