Technical Specifications
| Specification | Details |
|---|---|
| Operating Temperature Range | -40 to +105 / -25 to +105 |
| Rated Voltage Range | 6.3 to 100 VDC / 160 to 450 VDC |
| Capacitance Range | 0.47 to 15000 F / 0.47 to 470 F |
| Capacitance Tolerance | 20% (at 120Hz, +20) |
| Leakage Current (max.) | I 0.01 CV or 3 A (whichever is greater) at +20, after 2 minutes with rated working voltage applied. / I 0.03 CV A at +20, after 2 minutes with rated working voltage applied. |
| Dissipation Factor (tan, at 20, 120Hz) | Varies by Working Voltage. For capacitance >1000 F, add 2% per another 1000F. |
| Low Temperature Characteristics (at 120Hz) | Impedance ratio max. For capacitance >1000 F, add 0.5 per another 1000F for -25/+20; add 1 per another 1000F for -40/+20. |
| Load Life Test Conditions | Duration: 2000~5000 Hrs. Ambient Temp: +105. Applied Voltage: Rated DC working voltage. After test requirements at +20: Capacitance change 20%, Dissipation factor 200% of initial, Leakage current initial specified value. (160-450V: 2000hrs) |
| Shelf Life Test Conditions | Duration: 1000Hrs. Ambient Temp: +105. Applied Voltage: None. After test requirements at +20: Same limits as Load life. Pre-treatment for measurements: DC working voltage for 30 minutes. |
