toroidal inductor/toroidal coil

Toroidal coilApplications 1.Suppresses noise in DC circuits for switching regulators. 2.Protects primary AC side form being affected by a switching regulators. 3.Filters electorstic noise from power and signal lines. 4.Eliminates contact noise. 5.Filters incoming spike noise for Ics and equipment using microcomputers. 6.Minimizes noise emissions for conforming to FCC,VCCI,FTZ,CISPR,JTTC andVDE. 7.Minimizes noise emissions from inverters Toroidal coilElectrical Characteristics: 1.Operating Temperature range:-20 to +45 2.Storage temperature: -40to +70 3.Switching frequency:1KHz to 200KHz 4.Withstanding voltage:1500/3750Vac for 1 minute between primary&secondary 5.Insulation resistance:500Vdc 100MΩ min.between primar&secondary
