Common mode chokes, also known as line filters, differential mode chokes and EM filters, are a type of device used across a variety of applications. This article will discuss the application field of the ELF-11M010E and the working principle behind it.

The ELF-11M010E is a ferrite core common mode choke employed in low frequency switching power supplies and other high frequency circuits. It is typically used in power supply circuits, inverter circuits, and no-load transformer circuits. It has a wide frequency range, but is most effective in the range from 10kHz to 1MHz. The device offers excellent interference suppression characteristics, with a maximum insertion loss of 0.4dB, making it suitable for use in power supplies, as well as analog and digital signal applications.

The common mode choke works to reduce differential and common-mode noise from signal wires. It allows differential signals to pass through, but blocks any common-mode noise. This reduces the amount of noise or interference that is passed through the wires and is essential for systems that require high-fidelity signal transfer. The ELF-11M010E operates in a similar fashion. It has two separate winding sets, which act as an inductor to reduce common-mode noise from the signal wires. Each winding set contains two inductor coils which are wound around a ferrite core, providing the choke with greater interference suppression performance.

The ELF-11M010E is designed with two different EMI suppression modules. The first is a multi-layer EMI filter which uses capacitors, inductors, and resistors to filter out common-mode noise. The second module is a common-mode choke which reduces transformers and higher frequency. This combination provides excellent noise suppression in both differential and common-mode signals.

The ELF-11M010E also provides high impedance, low-frequency noise suppression. This feature reduces the power of low-frequency noise, allowing the system to better resist electrical noise. This is achieved by increasing the impedance of the choke coils, increasing their ability to reject noise signals.

In summary, the ELF-11M010E is a ferrite core common mode choke designed for use in low and high frequency circuits. It offers excellent interference suppression performance, with a maximum insertion loss of 0.4dB. The device has two separate winding sets which act as an inductor to reduce common-mode noise from the signal wires. It also has two EMI suppression modules, a multi-layer EMI filter and a common-mode choke, providing the device with greater noise suppression performance. Finally, it has high impedance and low-frequency noise suppression, which helps the system better resist noise signals.
