| WV(V) | Cap.(F) | Case sizeDL(mm) | Maximum allowable ripple current at 105/120Hz(A.r.m.s) |
|---|---|---|---|
| 6.3 (0J) | 6,800 | 2225 | 1.57 |

| 25 (1E) | 1,800 | 2225 | 1.33 |
| 63 (1J) | 560 | 2225 | 1.05 |
| 160 (2C) | 150 | 2220 | 0.66 |
| 250 (2E) | 56 | 2220 | 0.4 |
| 400 (2G) | 47 | 2220 | 0.37 |
Note: The endurance of capacitors is reduced with internal heating produced by ripple current at the rate of halving the lifetime with every 5 rise. When long life performance is required in actual use, the rms ripple current has to be reduced.
