dc filtering medium power film capacitors ffhv/fthv 1500vdc to 3000vdc 55 092315 the ffhv and fthv series are specifically designed for dc filtering applications such as dc link or resonant filters for voltages up to 3000v. these capacitors are proposed in 2 different versions: resin top for the ffhv series and hermetic case for the fthv. large case sizes up to 36 liters and high specific energy up to 380j/l together with safe and reliable controlled self healing technology make this series particularly suitable for power converters in traction, drives, renewable energy and power transmission areas. ffhv and fthv use a wet solution with polypropylene metallized film and oil (without free oil). standard designs proposed in this catalogue are covering a wide range of voltage and capacitance values. in case of specific requirements about shape and performances, feel free to contact your local avx representative. how to order ffhv series ffhv: resin top 1 section and option 1 = 340x125 2 connexions 2 = 340x125 4 connexions 3 = 340x175 2 connexions 4 = 340x175 4 connexions 1 height 1 = 230mm 2 = 295mm 3 = 370mm 4 = 450mm 5 = 530mm 6 = 610mm m terminal code f = female m = male r voltage r = 1500v s = 1750v n = 2000v t = 2250v p = 2500v w = 2750v x = 3000v 2637 capacitance eia code fthv series fthv: hermetic case d d 1 section and option 1 = 340x125 2 connexions 2 = 340x125 4 connexions 3 = 340x175 2 connexions 4 = 340x175 4 connexions 1 height 1 = 240mm 2 = 305mm 3 = 380mm 4 = 460mm 5 = 540mm 6 = 620mm m te r m i n a l code f = female m = male r voltage r = 1500v s = 1750v n = 2000v t = 2250v p = 2500v w = 2750v x = 3000v 2637 capacitance eia code ffhv non-painted rectangular resin filled aluminium case mounting brackets m8/17 female connections or m12/30 male connections 2 or 4 connections fthv non-painted rectangular aluminium hermetic case mounting brackets m8/17 female terminals or m12/30 male terminals 2 or 4 terminals packaging material standards ffhv iec 61071: power electronic capacitors iec 61881: railway applications, rolling stock equipment, capacitors for power electronics iec 60068-2: environmental testing ul 94: fire requirements nf f 16-101: rolling stock C fire behaviour C materials choosing nf f 16-102: rolling stock C fire behaviour C materials choosing, application for electric equipments en 45545-2: railways applications C fire protection on railway vehicles. part 2: requirements for fire behaviour of materials and components fthv iec 61071: power electronic capacitors iec 61881: railway applications, rolling stock equipment, capacitors for power electronics iec 60068-2: environmental testing en 45545-2: railways applications C fire protection on railway vehicles. part 2 : requirements for fire behaviour of materials and components
