Features: The power EMI filter is a reactive low-pass filter installed at the power input of electronic equipment. It can suppress both the noise transmitted through the grid cable and the high-frequency interference signal generated by the electronic equipment itself. High-quality imported components provide obvious filtering effect. EMI has become an essential device in electronic equipment. It is widely used in measuring instruments, building automation, machinery, elevator lifting equipment, automation systems, calculator inverter office equipment, servo system inverter equipment, frequency conversion equipment, lighting equipment, information and communication equipment, UPS power supply, automotive electronics, etc. Specifications: Material: PC + metal color as shown in the figure Module filtering category: 2-stage filter module current: 25A length: 9.5cm/3.7 inches weight: 50g (approximately) Note: The selection of EMI filter should take into account its operating voltage, operating current, and withstand voltage. The EMI filter should be installed at the power inlet to reduce radiation interference. It is best to choose twisted pair for the EMI filter connection line, which can eliminate some high-frequency interference signals. The input and output lines of the EMI filter must not be parallel and keep a certain distance to ensure the function of the filter. The E point of the EMI filter and the shell must be in good contact and connected to the ground wire.
