Ripple Current Coefficient Frequency Coefficient (at 105) See table for values at different frequencies (50Hz to 50kHz)
Maximum Allowable Ripple Current at 105/120Hz (A.r.m.s) Varies by WV(V) and Cap.(F)

Standard Ratings (Partial List)

WV(V) Cap.(F) Case Size (DL mm) Max. Ripple Current (A.r.m.s) at 105/120Hz
160(2C) 390 2225 1.37
160(2C) 470 2225 1.50
450(2W) 100 2225 0.73
450(2W) 120 2230 0.84
450(2W) 560 3545 2.20
450(2W) 680 3550 2.48

Note: Endurance of capacitors is reduced with internal heating produced by ripple current; halving the lifetime with every 5 rise. Reduce ripple current for longer life performance.
