Features: supply EMI filter is a kind of reactance-type low-pass filter, installed at the supply input of electronic equipment.It can inhibit noise transmitted through grid cable, and can inhibit high-frequency interference signals generated by the electronic device itself.High quality imported components provide obvious filtering effect.EMI has become a must have device installed in electronic equipment.Widely used for measuring instruments, building automation, machinery, elevator lifting equipment, automated system, calculator inverter office equipment, servo system inverter equipment, frequency conversion equipment, lighting equipment, information and communication equipment, UPS supply, automotive electronics, etc.Specifications:Material: PC+MetalColor as shownModule Filtering Categories: 2-stage filteringModule Current: 25ALength: 9.5cm/3.7inWeight: 50g(approx.)Note:The selection of EMI filter should consider its working voltage, working current, withstand voltage.EMI filter should be installed at the inlet of supply, to reduce radiation interference.It is better to choose twisted-pair cable as EMI filter connection cable, which can eliminate some high-frequency interference signal.EMI filter input and output cable must not be parallel, keep them from each other to a certain distance in order to the function of filter.E point and case of EMI filter must be in good contact, and connect to ground wire.Package Contents:1 x Filter BoardOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
