Common Mode Chokes

Common mode chokes are a type of electromagnetic component used in various applications for filtering and regulating electrical currents. The most common type is an ELF-18D656Q choke. ELF-18D656Q applications and working principles will be explained in this article.ELF-18D656Q chokes are powered by DC current, representing one of the most advanced types of filtering technology available. They are characterized by an inductance of 1.6 mH±20% and a maximum DC current rating of 1.5A. Additionally, they have a rated frequency of 16kHz and a rated voltage of 50V.The main purpose of a common mode choke is to limit high-frequency electromagnetic interference (EMI) and to reduce the amount of noise generated on a circuit. This noise reduction is achieved by allowing the EMI to pass through the choke’s magnetic core. The choke’s inductance also helps to reduce any residual EMI present on the power line.Another type of choke known as a diffractive choke works on similar principles to the ELF-18D656Q choke. However, these types are designed to reduce the quantity of differential noise and electromagnetic radiation produced by high-frequency signals. This is accomplished by using a combination of capacitors and inductors to generate a diffractive pattern on the circuit. The diffractive pattern absorbs and neutralizes any unwanted EMI.ELF-18D656Q chokes are often used in applications that require galvanic isolation, such as power supplies and isolated motor drivers. They can also be used in AC/DC power supplies and dc/dc converters. In fact, these chokes can be used in most applications where EMI is a factor.When selecting the correct size ELF-18D656Q choke for an application, it is important to consider the power requirements, current rating, and maximum frequency rating of the choke. In addition, it is important to ensure that the core is made of magnetic material that is compatible with the application.In short, ELF-18D656Q chokes are a valuable tool for filtering and regulating electrical currents. They are characterized by high inductance and provide a maximum of 1.5A DC current. Furthermore, they can be used to reduce high-frequency EMI and undesirable electrical noise.
