This power filter socket (model 03DEEG3E, also referenced as 20GEEG3E) is a compact antiinterference line filter designed for 220V AC circuits up to 3A. It reduces electromagnetic and radiofrequency interference on the mains line so small electronic devices run cleaner and more reliably. Key benefits Reduces line noise and interference that can cause audio hiss, display artifacts, data errors, or erratic behavior in sensitive electronics. Protects connected lowpower devices by filtering transient and steadystate interference on the power line. Simple, direct solution for improving signal integrity and device stability without complicated wiring or configuration. What it does and why you need it Provides pointofuse mains filtering for 220V AC systems rated to 3A, helping to prevent interference from adjacent equipment or noisy power sources. Useful in environments where small loads are affected by EMI/RFI (for example, audio equipment, communication devices, test instruments, and small control electronics). Helps reduce troubleshooting time by eliminating one common source of unexplained performance issues. Main attributes Model: 03DEEG3E (product code/reference: 20GEEG3E) Quantity: 1 Pc Function: Power line interference filter / filter socket Rated voltage: 220V AC Rated current: 3A Primary feature: Antiinterference (EMI/RFI) suppression Compatibility and performance Intended for use with devices and circuits that operate at 220V AC and draw no more than 3A. Ideal for lowpower electronic equipment that is sensitive to mains interference. Performance focuses on reducing interference on the AC line; not designed as a primary surge protector or current solution. Typical use cases Home audio and multimedia: Place between a small amplifier, DAC, or powered speaker and the wall outlet to reduce audible hum, buzz, or radiofrequency noise. Small office or lab electronics: Improve stability for routers, USB chargers, precision test instruments, or control modules that operate on 220V and draw under 3A. Embedded or control equipment: Use on small controllers, LED drivers, or test setups where mains noise can affect measurement or control accuracy. Installation and safe use Install inline with the AC supply to the device you want to protect. Follow standard electrical safety practices. Verify the connected device does not exceed the 3A rating. Overcurrent may damage the filter or connected equipment. Designed for 220V AC systems; do not use on voltages or frequencies outside the stated rating. What's included 1 Pc power filter socket, model 03DEEG3E (20GEEG3E) Choose this 220V AC, 3Arated antiinterference power filter socket when you need a compact, pointofuse solution to reduce mains noise and improve the reliability of lowpower electronic devices.
