3 / 21 page 1) Refer to chapter "General technical information, 5 Useful life" on how to interpret useful life. Specifications and characteristics in brief Rated voltage VR Surge voltage VS 350 ... 450 V DC 1.10 VR Rated capacitance CR Capacitance tolerance 1500 ... 22000 µF ±20% M Dissipation factor tan δ (20 °C, 120 Hz) ≤ 0.20 Leakage current Ileak (20 °C, 5 min) Self-inductance ESL d = 51.6 mm: approx. 15 nH d ≥ 64.3 mm: approx. 20 nH Capacitors with low-inductance design: d ≥ 64.3 mm: approx. 13 nH Useful life1) Requirements: 85 °C; V R; IAC,R > 12000 h ∆C/C ≤ 15% of initial value tan δ ≤ 1.75 times initial specified limit Ileak ≤ initial specified limit Voltage endurance test Post test requirements: 85 °C; V R 2000 h ∆C/C ≤ 10% of initial value tan δ ≤ 1.3 times initial specified limit Ileak ≤ initial specified limit Vibration resistance test To IEC 60068-2-6, test Fc: Frequency range 10 ... 55 Hz, displacement amplitude 0.75 mm, acceleration max. 10 g, duration 3 × 2 h. Capacitor mounted by its body which is rigidly clamped to the work surface. Characteristics at low temperature Max. impedance ratio at 100 Hz VR 350 V 400 V 450 V Z -25°C / Z 20°C 2 3 3 Z -40°C / Z 20°C 6 12 10 IEC climatic category To IEC 60068-1: VR = 350, 450 V DC: 40/085/56 ( 40 °C/+85 °C/56 days damp heat test) VR = 400 V DC: 25/085/56 ( 25 °C/+85 °C/56 days damp heat test) The capacitors can be operated in the temperature range of 40 °C to +85 °C, but the impedance at 40 °C should be taken into consideration.
