Fixed inductors are common electronic components used to store electrical energy and they have wide applications. The fixed inductor ELC-12E471L is no exception and has a host of unique characteristics and distinctions. This paper provides a comprehensive overview of the applications of the ELC-12E471L fixed inductor, as well as its working principle.

Overview

The ELC-12E471L fixed inductor is designed to provide high power capacity with a maximum DC current rating of 2.7 amperes. It has a self-resonant frequency of 1.7 MHz which allows it to be used in various HF and RF applications. Additionally, it has a high inductance value of 12uH, and a low AC resistance (DCR) of 0.15 ohm. This means that it has good efficiency and a low operating temperature when compared to similar inductors.

The inductor is packaged in a shielded cover that has a metalized coating. This ensures that the product will be able to withstand external vibrations with minimal interference and noise. Moreover, the ELC-12E471L has a rated operating temperature of -40°C to 125°C and can withstand voltages up to 100 V, allowing it to be used in many power related applications.

Applications

Due to its high power capacity, the ELC-12E471L inductor has a wide range of applications. Its wide inductance range and good efficiency make it suitable for use in low-to-medium power electronic circuit designs. It is commonly used in dc-dc converters, high-frequency rectifiers, and power line regulation circuits. Additionally, the ELC-12E471L is suitable for use in switching power supplies due to its low DC resistance and high self-resonant frequency.

The ELC-12E471L can also be used in many different types of HF and RF applications. It is ideal for signal filtering, instrumentation amplifiers, and signal broadcast applications. These applications require precise filtering of RF signals while minimizing the signal distortion.

The ELC-12E471L is also capable of providing good performance in high-frequency oscillators and voltage controlled oscillators (VCOs). VCOs are used to generate sinusoidal signals and highly precise timing signals in many communication and instrumentation circuits. As such, the ELC-12E471L can be used to meet the stability and accuracy requirements of these applications.

Working Principle

The working principle of the ELC-12E471L is based on the basics of inductive reactance. When a voltage is applied to an inductor, a magnetic field is created in the winding which opposes any further increase in current. This property, known as inductive reactance, is represented by the formula X = 2πfL. In this formula, f is the frequency of the applied voltage, and L is the inductance of the inductor.

The ELC-12E471L\'s high inductance of 12uH allows it to deliver a high level of reactance for high frequencies. This means that it can filter out high frequency signals while allowing the lower frequency signals to pass through at a lower level of distortion. Additionally, the ELC-12E471L\'s low DC resistance (DCR) prevents the inductor from overheating and allows it to deliver high levels of power.

Conclusion

The ELC-12E471L fixed inductor is an excellent choice for a variety of applications due to its high power capacity, wide inductance range, and low DCR. It is perfect for dc-dc converters, high-frequency rectifiers, switching power supplies, and many HF and RF applications, such as signal filtering and VCOs. Moreover, its working principle is based on the concept of inductive reactance, which allows it to filter out high frequency signals while minimizing signal distortion.
