Common Mode Chokes are electrical components used to block high voltage or current signals from passing through a circuit. They are also known as line filters, current/voltage filters, magnetic field filters, and transformer cores. The ELF-14M080E is a Common Mode Choke specifically designed for high-frequency applications such as LED drivers, router power systems, and consumer electronic circuits.

The ELF-14M080E

The ELF-14M080E is a high-frequency, high-inductance common mode choke with an inductance of 47.5 μH ±10% (at 500 kHz, 0.1 V). The ELF-14M080E is a miniature surface-mount device designed to save board space. This device has a low profile of 0.4 mm and is electrically equivalent to the ELF-14M core series.

ELF-14M080E Application Fields and Working Principle of Common Mode Chokes

The ELF-14M080E is an ideal choice for applications with high frequencies between 100 kHz and 500 kHz. Commonly, the ELF-14M080E is used to suppress common mode noise in power supplies, motor control systems, and LED drivers. The ELF-14M080E is capable of providing high-frequency, reliable, and effective electromagnetic field filtering.

Common Mode Chokes work by utilizing a combination of electrical and magnetic properties to block the passage of high-frequency signals. When a signal passes through a Common Mode Choke, it produces a small magnetic field. This magnetic field induces a current in the choke, which creates an opposing magnetic force. This opposing force blocks the passage of the signal through the choke. As a result, the high-frequency signal is attenuated, reducing noise and other interference.

The ELF-14M080E is designed to have an extremely high saturated flux density, low DC resistance, and a high Q factor. This ensures that the choke performs with low losses and high filtering effectiveness. The ELF-14M080E also has a high rated operating temperature of up to +105°C. This ensures reliable and consistent performance, even in the most extreme operating conditions.

Conclusion

The ELF-14M080E is a miniature, high-efficiency, surface-mount Common Mode Choke designed for high-frequency applications such as LED drivers, router power systems, and consumer electronics. This device offers reliable electromagnetic field filtering with low losses and high saturation flux density, perfect for reducing noise and other interference.
