Common Mode Chokes

Common mode chokes are designed to provide a high degree of electrical isolation between two connected circuits. Generally, common mode chokes are used to suppress certain types of interference in low voltage and medium voltage applications. The ELF-21N035A is one such example of a common mode choke.

First, let\'s look at the ELF-21N035A\'s application field. The ELF-21N035A is typically used in inverters, uninterruptible power supplies, switching power supplies, and motors. It has a rated current of 4A, a continuous withstand voltage of 680V, and a peak withstand voltage of 1500V.

Now, we should look at the working principle of the ELF-21N035A. The typical common mode choke consists of two coils with insulated windings. These coils are connected in series to produce an inductance between their input and output terminals. When an AC signal flows through the two coils, any interference signal will generate a magnetic field in the coil, which induces a voltage in the coil. This induced voltage opposes the AC signal, thus reducing the interference and providing electrical isolation between two connected circuits.

The ELF-21N035A is a typical example of a common mode choke. It uses two coils to provide high electrical isolation between two circuits and reduce the impact of interference. With a rated current of 4A, continuous withstand voltage of 680V, and peak withstand voltage of 1500V, the ELF-21N035A is suitable for a wide range of applications, including inverters, uninterruptible power supplies, switching power supplies, and motors.
