Common Mode Chokes, also known as isolation transformers, are used to reduce the amount of conducted and radiated electromagnetic interference and noise in a circuit. The ELF-17N017A, an isolation transformer, is a Common Mode Choke specifically designed to reduce and block both the common mode current and differential mode current within a circuit. This current transformer packs a load capacity of up to 1500 VA in a circular form factor, ideal for any environment where space is limited. The ELF-17N017A offers highest performance in a small form factor, ensuring a long lifespan of quiet operation with minimal loss.

The ELF-17N017A offers a wide range of applications, like filtering out common mode current between various power sources or components, isolating different networks, and suppressing high frequency noise. Mainly, this Common Mode Choke is used when multiple networks must be combined without developing common mode noise.

The ELF-17N017A works as an isolation transformer in a circuit, and is composed of a primary windings, secondary windings, and third windings. These three windings are interconnected via capacitors, forming a three-phase transformer with four windings. This type of transformer does not have any direct connection between their windings, thus any voltage applied on the primary winding will not generate a current in the secondary winding, preventing direct current flow between two separate nets.

Additionally, the ELF-17N017A works as a Common Mode Choke by providing a differential path between the primary and secondary windings, allowing common mode noise to pass through. By inserting this choke in a circuit, it forms a low-impedance connection between the two networks, where the choke absorbs and eliminates this noise.

As a result, the ELF-17N017A can offer effective common mode noise attenuation in a wide range of applications. The high efficiency and low-profile design of this choke allows it to be used in any environment where space is limited. Furthermore, the ELF-17N017A boasts high durability, ensuring a long lifespan of quiet operation with minimal loss.
