Features 1.THREE STAGE FILTERING: Filter board consists of three filtering stages, the first stage LC filtering circuit, the second stage common mode EM filtering, and the third stage LC filtering circuit. 2.LC FILTERING: LC filter is generally known as passive filter, which is a traditional DC power supply harmonic compensation device composed of inductor and capacitor. 3.COMMON MODE FILTERING: EMI power filter board can filter out harmonics in power supply in single or multiple times, purify DC power supply, common mode filtering. 4.SUPPRESSION: DC EMI power filter can be used to suppress the problem of fast transient group pulse interference with a repetition frequency of several kilohertz at certain user sites. 5.APPLICABLE: DC LC filter can be applied to the switching power supply output after filtering, automotive, motorcycle electromagnetic interference is relatively strong DC circuit. 6.INPUT AND OUTPUT PORTS: Power supply filtering board input port IN+ IN? (two wire 7.62 terminal input). The output port is output + output ? (two wire 7.62 terminal output). specificationItem Type: DC EMI Power Filter_x000D_ Material: PCB_x000D_ Input: DC_x000D_ Output: DC_x000D_ Socket: 7.62_x000D_ Voltage: 50V PackageList1 x_x000D_ _x000D_ DCEMIPowerFilter NotePlease allow some error due to manual measurement.
