400USG270MEFCSN30X25 [rubycon]

USG series aluminum electrolytic capacitors feature snap-in terminals and are designed for 85°C operation with a load life of 3000 hours. They are RoHS compliant. The capacitors cover rated voltage ranges of 160-250V DC and 400-450V DC, with a category temperature range of -40°C to +85°C for 160-250V and -25°C to +85°C for 400-450V. They have a capacitance tolerance of ±20%, low leakage current (I=3CV after 5 minutes), and a dissipation factor of 0.2 max at 120Hz. The endurance test requires 3000 hours at 85°C with rated ripple current, after which capacitance change is within ±20%, dissipation factor not more than 200% of initial, and leakage current not exceeding the specified value. Low temperature stability is characterized by impedance ratios: for 160-250V, Z(-25°C)/Z(20°C) max 4 and Z(-40°C)/Z(20°C) max 12; for 400V, Z(-25°C)/Z(20°C) max 8; for 420-450V, Z(-25°C)/Z(20°C) max 12. Ripple current multipliers are provided for frequencies from 60Hz to 10kHz.
