It is suitable for a variety of circuits and in situations that require high-frequency, consistent, and reliable operation.The MPIA4040R3-2R2-R has a standard impedance rating of 50% and a wide frequency response range of 25kHz - 2.2GHz. It can be used with power supplies ranging from 5V to 24V. The fixed inductor features an inductance range from 1.5µH to 40µH and an air gap of only 0.5µH, enabling its flatter frequency response and improved signal integrity. The unit is manufactured using an ultra-thin conductor and has a very uniform diameter for a stable inductance value and a small size. It is available in a 1k SMD package and is RoHS compliant.Working Principle The working principle of an inductor is based on Faraday’s Law of Induction. Faraday’s law states that when a conductor passes through a magnetic field, an electrical current is induced in the conductor itself. This induced current is dependent on the strength of the magnetic field, the speed of the current, and the surface area of the conductor.The basic structure of a fixed inductor is a wire or coil wound around a ferrous core. The use of this ferrous material induces a magnetic field in the coil, which in turn produces the desired electromagnetic effect. This is the basic working principle of the MPIA4040R3-2R2-R inductor.In addition to its ferrous core, the MPIA4040R3-2R2-R has an air gap between the end of the coil and the core. This air gap increases the inductance, allowing for a wider frequency response. This feature enables the device to be used in a variety of high-frequency applications such as sensors, radio frequency identification (RFID) tags, and communication systems.Applications The MPIA4040R3-2R2-R fixed inductor is suitable for a wide variety of applications where high using the correct components, one can design a circuit that is not only reliable, but also performant.Some of the applications of the MPIA4040R3-2R2-R fixed inductor include:

• Joystick circuit designs
• RFID tags
