Common Mode ChokesCommon mode chokes are typically used in applications requiring suppression of common mode interference from power supply systems. They are also referred to as “noise” filters as they provide noise and electromagnetic interference (EMI) suppression. Common mode chokes are typically provided in the form of configurations that coil around the power supply line. The coil should be around 10 times the size of the cable line. Common mode chokes use inductance to suppress noise and electromagnetic interference in power supplies. Inductance is the ability of electrical components to resist changes in current flow and react to changes in current flow.The LF2823NP-393 is a low frequency, non-polarized common mode choke specifically designed to suppress common mode interference on power supplies. It uses dual common mode inductors in order to provide effective frequency range up to 1MHz and current up to 3A. The LF2823NP-393 consists of two identical windings that are centered in the core and provide the desired isolation. The LF2823NP-393 has a very low DCR (direct current resistance) of 0.14Ω, making it ideal for high current applications.The working principle of the LF2823NP-393 is based on Faraday’s Law of Induction. This law states that a changing magnetic field induces an electric field, and vice versa. In the case of the LF2823NP-393, the electric field and the power supply line induce an opposing magnetic field which helps to suppress the common mode interference. The LF2823NP-393 enables the transmission of signals without interference by blocking the current generated by the power supply line.The LF2823NP-393 application fields can be found in various applications such as audio systems, control systems, lights, and harsh industrial environments. It is designed to effectively suppress noise and EMI at frequencies up to 1MHz. The LF2823NP-393 is designed for low profile solutions and has a wide temperature range (-40°C to 125°C). It also offers high vibration and shock resistance.The LF2823NP-393 is an ideal choice for power supplies that require isolation or common mode suppression. The excellent inductance and low DCR makes the LF2823NP-393 extremely efficient for filtering out ambient noise or electromagnetic interference. LF2823NP-393 provides excellent performance and is an ideal solution for applications requiring common mode chokes.
