Introduction

Fixed inductors are types of electronic components used in all sorts of electronic applications. Inductors are defined as components that store and release energy in the form of electric and magnetic fields. The HKQ04024N7S-E Fixed Inductor, in particular, is a high-performance, cost-effective solution for use in a range of applications. This article will discuss the application field of this product as well as its working principle.

Application Field

The HKQ04024N7S-E Fixed Inductor is designed for applications such as power supplies, LED lighting, computers, consumer electronics, mobile phones, and many other electronic applications. It features an operating temperature of -40°C to +125°C and is rated for 4.7uH (±5% tolerance). The package size for this product is 0402 which is ideal for use in space-constrained applications.This product is widely used in a variety of applications which require high-frequency operation or high power levels. In LED lighting, it is used as a current limiter to protect LED lamps from over-current and ensure that they do not exceed their maximum ratings. In mobile phones, it can be used as an antenna matching circuit in order to optimize its performance. In computers, it is used as a filter element to reduce or eliminate electromagnetic interference.

Working Principle

A fixed inductor is essentially an electric coil made of copper wire, which works on the principle of electromagnetic induction. When a voltage or current is applied to one end of the coil, it produces an electromagnetic field. This will then induce a current in the opposite direction to the current being applied.The HKQ04024N7S-E Fixed Inductor works in the same way as all other fixed inductors; the only difference is that it is designed to be used at higher frequencies and power levels. This product has a high self-resonant frequency of 5 MHz, allowing it to be used for higher frequency equipment. It also has an inductance of 4.7uH, which allows it to be used in power supply designs that require high power levels.The working principle of this product can be illustrated using the following diagram. When a voltage or current is applied to the coil, it produces an electromagnetic field. This field then produces an opposite current in the opposite direction to the current being applied, and this induces a voltage across the coil. The size of this voltage is determined by the size of the inductance.

Conclusion

The HKQ04024N7S-E Fixed Inductor is a high-performance, cost-effective solution for use in a range of applications. It is suitable for use in power supplies, LED lighting, computers, consumer electronics, mobile phones, and many other applications. This product has a high self-resonant frequency and a high inductance rating, making it suitable for use in high-frequency and high power applications. Its working principle can be summed up as an electromagnetic field inducing a voltage across the coil, based on the size of the inductance.
