Fixed inductors are components used in electronics, mostly for AC signals. They are composed of windings, a core, and terminals, which are connected to a circuit. ELC-18B331L is a type of fixed inductor. Its application field and working principle are discussed in this article.

Application Field

ELC-18B331L is mainly used for filtering and decoupling applications in various circuits. It can reduce or eliminate the frequency components of the signal, which improves the signal or power supply quality. Besides, its inductance value is stable, and its rated Q is 16 and 18 at 100kHz and 10MHz respectively. Moreover, it is suitable for applications where high rated current is needed, since its rated current can reach 5A. This makes it well suited for use in different situations when an inductor is required.

Working Principle

ELC-18B331L is an air-core inductor, which means it does not have any material as its core. The working principle of an air-core inductor is based on Faraday\'s law of induction, which states that a current passing through a conductor generates a magnetic field. This magnetic field induces a voltage in an adjacent coil, thus creating a self-inductance effect. This inductance effect has a set value, which cannot be changed. When current is flowing through ELC-18B331L, the induced voltage in the coil will create a self-consistent oscillating magnetic field around the coil. This inductance effect is what makes an inductor behave like a filter, blocking or changing the frequency components of the signal.

Conclusion

ELC-18B331L is a type of fixed inductor suitable for filtering and decoupling applications. Its rated current and Q are high and stable respectively, making it well suited for various circuits. The working principle of ELC-18B331L is based on the Faraday’s law of induction since it is an air-core inductor. Therefore, the inductance effect is created through this magnetic field generated when current is flowing through the coil. With this in mind, ELC-18B331L can be used successfully in various applications when the correct inductor is needed.
