3 / 25 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 200 ... 500 V DC 1.15 VR (for VR ≤ 250 V DC) 1.10 VR (for VR ≥ 350 V DC) Rated capacitance CR Capacitance tolerance 820 ... 33000 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 Useful life1) 200 ... 450 V 500 V Requirements: 85 °C; V R; IAC,R > 15000 h > 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 ≤ 250 V ≥ 350 V Z -25°C / Z 20°C 5 4 Z -40°C / Z 20°C 20 16 IEC climatic category To IEC 60068-1: 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.
