Description Features: Power supply noise is a kind of electromagnetic interference, and the frequency spectrum of its conducted noise is roughly 10kHz to 30MHz, and the maximum can reach 150MHz. The electromagnetic interference filter can suppress both series mode and common mode interference. The filtering effect is obvious after using high-quality imported components to produce and use This product is widely used in precision measuring instruments, building automation, precision machinery and equipment, elevators lifting equipment, automation system lighting, information communication equipment, UPS switching power supply, automotive electronics and other equipment brand new and high quality The power EMI filter is a reactive low-pass filter, which is installed at the power inlet of the electronic equipment. Specifications: Secondary Filter Size:approx width 28mm x length 98mm x height 19mm/1.1x3.86x0.75in Material:Metal Note: The selection of EMI filter should consider its working voltage, working current and withstand voltage value. EMI filters should be installed at the power inlet to reduce radiated interference. It is better to use double glue line for EMI filter connection line, which can eliminate some high-frequency interference signals. The input and output lines of the EMI filter should not be parallel, and a certain distance should be opened to ensure the function of the filter. The E point of the EMI filter and the chassis must be in good contact and connected to the ground wire. Package includes: 1 Set x EMI Filter
