For operation below 1 khz, the ESR will need to be adjusted using the following equation: ESR - 31.83/(1C + 31.83/(fC. Determine Thermal Resistance at Operating Frequency and Air Flow Compute Θ = Θ CC + Θ CA. In the ratings tables, Θ CA is for still air. For v = to m/s, multiply Θ CA by [( + 17.6(.1.66 / ( + 17.6(v +.1.66 ] Determine Expected Lifetime Look up Expected Lifetime on the graph using V A /V R and T C = T A + I 2 (ESR/1 Θ The maximum allowed temperature rise is 4 C and the maximum allowed core temperature is 9 C. 1.7 Expected Lifetime vs Core Temperature and Applied DC Voltage 1.6 1. 1.4 ºC Va / Vr 1.3 1.2 6ºC 7ºC 1.1 1 8ºC.9.8 1 1 1 1 1 Expected Lifetime (h CDE Cornell Dubilier 16 East Rodney French Blvd New Bedford, MA 2744 Phone: (8996-861 Fax: (8996-38
