ELF-17N030A

Common mode chokes, also known as CM chokes, are an important component of electrical noise suppression and power line filtering. They are widely used in a variety of applications, including power line and communications networks, automotive electronics, digital telecommunications, and consumer electronics. The ELF-17N030A is commonly used in these applications, as it is a high-performance common mode choke with superior performance specifications. This article will discuss the application field and working principle of the ELF-17N030A.

The ELF-17N030A is a three-phase, non-inductive, common mode choke. It is mainly used in power conversion systems, such as solar inverters, inverter drives, and AC/DC converters. Its main features include low insertion loss, wide operating temperature range, high inductance, and low noise. The ring core construction of the ELF-17N030A is designed to provide excellent suppression of EMI and conducted noise, while its non-inductive design is ideal for noise suppression applications.

Common Mode Choke Working Principle

The ELF-17N030A works by passing the current in two paths. The first path is from the power source to the load, while the second path is the return path. This creates two inductances, which in turn produce a choke effect. This choke effect creates a magnetic field, which induces a counter electromotive force (CEMF) that opposes the current flow in the two paths. This CEMF reduces the amplitude of any conducted disturbances on the power line.

In addition to the suppressing electric noise, common mode chokes also reduce the harmonic distortion of the supply current. Harmonic distortion is produced by non-linear loads, such as rectifiers, and can affect the operation of other devices connected to the load. By reducing the harmonic distortion of the supply current, common mode chokes are able to reduce its adverse effects on other devices.

Common mode chokes are an essential component of any noise suppression system. Their ability to reduce EMI and conducted noise, as well as harmonic distortion, make them ideal for a variety of noise suppression applications. The ELF-17N030A is a high-performance common mode choke with superior performance specifications, making it an ideal choice for these applications.
