Fixed inductors refer to inductors that generally have a fixed inductance and can be used for circuit tuning. The ELC-18B271L is an inductor component of the same type. It has a wide range of applications and uses a fixed core working principle.

ELC-18B271L is a low-profile, standard SMD fixed inductor for enhanced EMI Suppression. Its operating temperature range is -40 to +85°C, and its size is only 1.85mm x 1.85mm x 1.35mm, so it is suitable for use in many small electronic products.

The fixed inducters, such as ELC-18B271L, help suppress the spikes in a circuit’s current draw. They are often used for EMI suppression, noise filtering, and bypass applications. EMI suppression is especially critical in applications such as automotive electronics, home appliances, computer peripherals, and IoT devices, as their integrated design poses a higher risk of electromagnetic interference.

ELC-18B271L’s working principle is based on the principle of induction that Faraday discovered in 1836. The inductance is determined by the number of turns of the coil and by the area and orientation of the coil in relation to the ferromagnetic core. The ferromagnetic core works to amplify and boost the reaction of the inductor C. In electrical circuits, the inductor C reacts when the voltage changes suddenly. It acts as a short-term energy storage medium. The energy stored in a capacitor is discharged in short spurts, while the energy stored in an inductor is slowly and steadily released.

With a low DC resistance and a rated current up to 145mA, the ELC-18B271L can efficiently regulate noise, such as EMI, in the circuit. It can be used in a wide range of applications including switching power supplies, IGBT inverter modules, radio frequency circuits, telecom systems, and audio equipment. The ELC-18B271L is a reliable and cost-effective solution for many EMI suppression applications.

In summary, the ELC-18B271L Fixed Inductor is a small but powerful EMI suppressing device with a wide range of applications. It has a fixed core working principle based on the principles of Faraday\'s induction, and can be used in many devices to help regulate noise and interference in the circuit. The small size and high rated current make it an excellent choice for many EMI suppression solutions.
