Topic:KT Use technique of aluminum electrolytic capacitors
Content:
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 operationL = 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.
