Technical Specifications
Performance Characteristics
| Specification | Value |
|---|---|
| Operating Temperature Range | -40 to +105 |
| Rated Voltage Range | 6.3 to 100 VDC (for some variants), 160 to 450 VDC (for other variants) |
| Capacitance Range | 0.47 to 15000 F (for some variants), 0.47 to 470 F (for other variants) |
| Capacitance Tolerance | 20% (at 120Hz, +20) |
| Leakage Current (max.) | I0.01 CV or 3 (A) after 2 minutes measured with rated working voltage applied. (for some variants) I0.03 CV (A) after 2 minutes with rated working voltage applied. (for other variants) |
| 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 time: 2000~5000 Hrs. Ambient temperature: +105 Applied voltage: Rated DC working voltage After test requirement at +20: Capacitance change 20% of initial value, Dissipation factor 200% of initial specified value, Leakage current initial specified value. |
| Shelf Life Test Conditions | Duration time: 1000Hrs Ambient temperature: +105 Applied voltage: None After test requirement at +20: Same limits as Load life. |
| Pre-treatment for measurements | Application of DC working voltage for 30 minutes. |
