Introduction to 5022R-112F Fixed Inductors

Fixed inductors, generally referred to as ‘ Iron-Cores’, are an ideal choice for power transfer applications due to their lower loss, high storage capacity, and low power consumption. The 5022R-112F Fixed Inductor from Coilcraft is an example of these magnetic components that make the most out of the advantages they offer. This article will explore the application fields and working principle of the 5022R-112F Fixed Inductor in detail.

Application Fields

The 5022R-112F Fixed Inductor, as its name suggests, can be used in fixed places or locations as it is designed to withstand high temperatures, shock and vibration. With the high thermal capacity, the inductor can handle high current in tight spaces. This allows the 5022R-112F to be used in applications such as switching power supplies, DC/DC converters, voltage regulators, snubber circuitry, and EMI filters. The 5022R-112F is also commonly used to reduce EMI and provide a stable voltage source.

Advantages

The 5022R-112F has several advantages over other fixed inductors. For starters, it is designed to perform reliably in applications with high levels of vibration, shock, and temperature. Additionally, it has a low DCR (coil resistance), which makes it ideal for efficient power transfer. The 5022R-112F also features a wide inductance range, with values from 0.48 to 18uH, allowing it to be used in applications ranging from power conversion to frequency control. Lastly, its 4mm x 5mm size makes it an excellent choice for applications with space constraints.

Working Principle

The working principle of the 5022R-112F Fixed Inductor is based on the principle of electromagnetic induction. It consists of a metal core and two windings that are wound in opposite directions around the core. An alternating current flows through the windings, creating a varying magnetic field. When an external current is applied, the magnetic field induces a voltage in the windings, which in turn causes a current to flow. This current is stored in the core and slowly released over time, providing a steady voltage source.

Conclusion

The 5022R-112F Fixed Inductor is a reliable and efficient magnetic component with a wide range of applications. With its low power consumption, high storage capacity, and excellent thermal performance, the 5022R-112F is an ideal choice for power conversion and voltage regulation. By utilizing the principle of electromagnetic induction, the 5022R-112F can provide a steady voltage source and reduce EMI.
