KT 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.
