Fixed inductors are one of the most useful components in the field of electronics. Among them, LK1005R47K-T is widely adopted due to its superior performance, but what makes it special? This article is about the application field and working principle of LK1005R47K-T, aiming to clarify the key features for a better utilization.

Overview of LK1005R47K-T

As indicated by its type name, LK1005R47K-T is a miniaturized fixed inductor, offering a number of 8 different inductance values from 1.5µH to 47µH. It adopts an epoxy resin base and CNS based lead wires and is wound with aluminum wires (enameled copper wires for RoHS version). It achieves 10Ω/μH to 20Ω/μH DC resistance and 40A direct current rating, being both cost-effective and reliable.

Application Fields

LK1005R47K-T is designed with wide temperature range in mind, operating as stably as 0℃ to 80℃. This characteristic renders it suitable for a variety of equipments, such as desktop PC, server, workstation that require stability and high temperature endurance.

Furthermore, its minimized size and high direct current rating make it an ideal component for power factor correction, a process for reducing reactive power and ultimately improving the efficiency and power factor of a system’s power supply. Thus, LK1005R47K-T is frequently adopted in display equipment, industrial control devices, and other high-performance components.

Working Principle

To understand the superiority of LK1005R47K-T, a brief explanation of the principle of inductor is necessary. In a nutshell, inductor is a basic electronic component, which introduces reactance in opposition to steady electric current, and reduces the amplitude of alternating current. It is an electromagnetic device, which stores energy in its magnetic field, in the form of either direct current or alternating current.

To overcome the problem of heating, LK1005R47K-T adopts a micro-based construction, with interwound winding on top of the fixed core. By reducing the effective cross-section of surmount ED cores and improving the winding density, the inductors are able to achieve high temperature durability, and higher inductance in a much smaller size than any other components of the same capacity.

In addition, it processes built-in airtight epoxy resin for protection of lead wires and internal winding, effectively decreasing the heat generated and improving efficiency. The wound wires are combined with varnish coated materials, adding a layer of insulation to the system.

Conclusion

LK1005R47K-T is a miniaturized fixed inductor, offering impressive temperature durability and cost-effectiveness. It is used in a wide range of applications, such as power factor correction, desktop PC, and display equipment, and its superior performance is due to a combination of winding design, epoxy resin base, and CNS based lead wires.
