Fixed inductors are an important part of any electrical and electronic circuits. An inductor is a passive two-terminal electrical component that stores energy in a magnetic field when electric current is flowing through it. The ELC-16B4R7L is a high-efficiency, fixed inductor suitable for use in a wide variety of applications. This article will discuss the application fields and working principles of the ELC-16B4R7L.
Application Field
The ELC-16B4R7L is a small, high-efficiency fixed inductor used in a variety of electronic applications such as switching power supplies, DC/DC converters, step-down converters, inverters, and power factor correction circuits. It is an ideal choice for high-frequency current-ripple and noise filtering, power distribution, electromagnetic interference suppression, etc. The ELC-16B4R7L has a low DC resistance to minimize power loss, and its low inductance value makes it suitable for high-frequency switching power supply applications. The inductor has a wide operating frequency range of 10kHz to 100kHz, and can easily handle up to 2A of current. The device also features a built-in snubber circuit to protect it against over-voltage transients and excessive current.
Working Principle
The working principle of the ELC-16B4R7L is based on electromagnetic induction. When a current flows through the inductor, it creates a magnetic field. This changing magnetic field induces a voltage in the inductor, which is proportional to the rate of change of the current. This induced voltage opposes the current flow in the inductor, resulting in a damping effect. This property of inductors is used to filter out high-frequency currents and noise, as well as to limit the voltage or current in a circuit.
The ELC-16B4R7L is a highly efficient, fixed-value inductor. It has a low DC resistance and wide operating frequency range, making it ideal for high-frequency current-ripple and noise filtering, power factor correction, and power distribution applications. The device also features a built-in snubber circuit to provide enhanced protection against over-voltage transients and excessive current.
