Introduction

Fixed inductors are integral components in all kinds of electrical circuits. They help regulate and control current flows, store energy and filter out certain frequencies of signals or interference. The ELL-4FG100MA, manufactured by Johnson Electric, is a type of fixed inductor. This article looks at the application field and working principle of the Ell-4FG100MA in detail.

Application Field

The ELL-4FG100MA is mainly used in power supplies and DC converters, where it helps regulate voltage and current levels, and provides a wide range of inductance and peak current ratings. Where higher performance is needed, the ELL-4FG100MA can be used in power factor correction applications and as part of a resonant circuit for active filtering. In addition, the ELL-4FG100MA can also perform as an integral part of automotive control systems. Its high performance and low loss make it well suited for many applications in new energy vehicles, such as motor drives, on-board recharging, battery management systems, DC/DC converters and transmission control systems.

Working Principle

The ELL-4FG100MA is a fixed inductor. This involves passing a direct current through the device, which sets up an opposing magnetic field that creates a voltage counteracting the direct current. This slows the current flow, thereby regulating the current in the circuit. The ELL-4FG100MA features an open construction design. This improves heat dissipation and reduces power losses in the inductor, allowing for higher power rating for a given size. Additionally, the construction of the ELL-4FG100MA helps minimize electrical noise, and its high-frequency properties make it suitable for various resonant circuits and harmonic filtering applications. The ELL-4FG100MA is also designed to be vibration and shock resistant. Its components are securely mounted and made of resistant materials, making it reliable in dynamic and harsh industrial environments.

Conclusion

The ELL-4FG100MA is a highly versatile fixed inductor that provides a range of features and benefits for power supply and DC converter applications. Its design allows for efficient and reliable operation in a range of operating conditions, thanks to its high performance and low loss construction, vibration and shock resistance, and a wide range of inductance and peak current ratings.
