Power Line Filter Modules - ESM-10-221-D Application Field and Working PrinciplePower Line Filter Modules (PLFMs) are a kind of electronic components used to ensure that power supply lines or output lines are free of disturbing electrical interference. They are designed to meet the exact requirements of specific applications. One example of this type of filter is the ESM 10-221-D series, which is a common choice for high-speed data transmission, voice and video applications.The ESM 10-221-D series is an efficient power line filter module designed to reduce the level of EMI (Electromagnetic Interference) in high-speed data transmission, voice and video applications. It features a unique ferrite-based design that allows for high-frequency noise suppression with very low insertion loss. The filter utilizes low pass filters to reduce high-frequency interference while allowing the signal to current pass through. The module also includes a line choke which helps to reduce common-mode noise from the terminals and increase the ease of EMI filter installation.The application field of the ESM 10-221-D series is broad, covering high-speed data transmission, voice and video applications. It is suitable for use in power and data communication systems, telecommunication power supplies, power amplifiers, internal interference attenuation, and signal conversion.The working principle of the ESM 10-221-D series is relatively simple. It utilizes a high-frequency common-mode choke to attenuate high-frequency interference. The filter consists of two parts: the ferrite-core high-frequency common-mode choke and the low pass filter. The choke helps to prevent the signal from picking up interference, while the low pass filter helps to prevent any interference from entering into the device through the power line.The ferrite-core high-frequency common-mode choke consists of a cylindrical coil made of high permeability ferrite. The coils are wrapped around the core to allow for high-frequency noise suppression and to act as a shield against external electromagnetic interference. The low pass filter utilizes inductors connected in series and parallel with capacitors. This combination helps to reduce any high-frequency noise before it can enter the device.Overall, the ESM 10-221-D series is an effective power line filter module for high-speed data transmission, voice and video applications. It features a ferrite-based design that can reduce EMI without compromising signal integrity. The filter is suitable for a variety of applications and is easy to install.
