Kingtronics Use Technique of Aluminum Electrolytic Capacitors

Example

1)Expected life of equipment (required conditions)
A︓10 years with 24h operation
B︓10 years with 8h operation a day

2)Ambient temperature of capacitor   
65℃ (Check ・ no heat generated part on reverse or around)

・Capacitor selection

case 1) 

A︓For 10 years with 24h operation
      L = 24(hour)× 365(day)× 10(year)
        = 87600(hour)→ Working hours for 10 years
    Because the value is larger than 32000 hours, the 105℃ 2000h product does not satisfy the expected life, and the ambient temperature should be lowed.

Case 2) 

B︓For 10 years with 8h operation a day
      L = 8(hour)× 365(day)× 10(year)  
       = 29200(hour)→ Working hours for 10 years   
  Because the value is smaller than 32000 hours, the105℃ 2000h product can be used.
