Fixed Inductors

Fixed inductors are widely used in various electronics applications in the fields of signal transmissions, frequency filtering, resonating and power supplies. Among various types of fixed inductors, the MPI5451R1-3R3-R is one of the most popularly used and highly reliable products.

Application Field

The MPI5451R1-3R3-R fixed inductor is designed for use with DC/DC converters. Due to its high power factor, it is perfect for output filtering, particularly when it comes to frequency filtering applications such as switching converters and DC/DC converters. This type of inductor can also be used in automotive and industrial applications thanks to its superior EMI performance.

In addition, the MPI5451R1-3R3-R fixed inductor is also ideal for applications that require a high saturation current and low DC resistance. It is particularly suitable for DC/DC converters, voltage stabilizers, telecom power systems, lighting systems, and power management applications.

Working Principle

The MPI5451R1-3R3-R fixed inductor works on the basic principle of an inductor, which is the resistance displayed by an electric circuit when current starts to flow through it. As the current increases, the inductor’s opposition to the flow of current also increases, which in turn results in a drop in current. This is known as the ‘inductive reactance’ of the circuit.

The MPI5451R1-3R3-R inductor features a winding count of 17. This winding count is determined by the number of cycles of the current, which in turn is based on the number of turns in the coil. The higher the winding count, the higher the inductance, meaning the more current it can store. The higher the inductance, the better the inductor’s ability to filter out noise and remain stable in the most extreme conditions.

This type of inductor also features a high saturation current, meaning that it can handle more current before its inductance begins to dissipate. For this reason, the MPI5451R1-3R3-R is especially well-suited for high-frequency applications where current levels are high. It is also characterized by low DC resistance, making it an ideal choice for applications where heat dissipation must be minimized.

In summary, the MPI5451R1-3R3-R fixed inductor is a reliable, high performance inductor that is suitable for a wide variety of applications. Its user-friendly characteristics make it ideal for applications requiring efficient noise filtering and EMI protection.
