Common Mode Chokes

A common mode choke, also known as a common mode inductor, is a type of electronic component used to reduce, or “choke,” the amount of common mode noise or interference. This type of electronic component is used to reduce the amount of unwanted noise and interference in electrical systems, such as circuits located near motors, wiring, and other electrical devices. Common mode chokes are commonly used in EMI/RFI filters, surge suppressors, and power supplies.

ALFT-04-10 Application Field and Working Principle

The ALFT-04-10 is a series of common mode chokes manufactured by an electronic component company. It is designed for applications that need to reduce noise and interference and are environmentally resistant. It has excellent mechanical characteristics, including a wide range of temperature and humidity-resistance. Additionally, its performance is unaffected by mechanical shock or vibration.

The working principle of a common mode choke is to provide an alternating current (AC) path through several high permeability cores that have the same effective inductance as the source and load paths. This arrangement allows the common impedance between source and load to be reduced without sacrificing the inductance value. By reducing the common impedance, the ability of noise and interference to pass through the circuit is also reduced. The inductance value of the ALFT-04-10 is 0.4mH.

The core material of the ALFT-04-10 series is a ferrite core material which is corrosion-resistant and has low power loss. Moreover, due to its corrosion-resistant qualities, the ALFT-04-10 can be used in a variety of conditions. The assembly of this series is a shielded core which provides even better shielding.

Besides the fabrication of common mode chokes, ALFT-04-10 is also a perfect choice for applications such as fuel injection system, electric motors, welding equipment, and power transformers. Moreover, it is suitable for use in high-frequency applications and filters. The overall figure of merit of the ALFT-04-10 is 1.58μH, which is highly important when selecting the correct common mode choke that fits the requirements of the application.

The ALFT-04-10 series is an extremely versatile component that reduces the amount of noise and interference. Its appearance and durability makes it an ideal choice for a wide variety of electronic components. The excellent mechanical characteristics and wide range of temperature and humidity-resistance make it a perfect choice for applications in the automotive and white goods markets, as well as other applications that require strong environmental protection.
