TA-I TECHNOLOGY CO., LTD
Derating ratio for different ambient Temperature
Referring to bottom figure and select the appropriate derating ratio :
e.g., Ambient temperature is 60 degree C
the derating ratio
0.95
Calculating the required rating of fuse needed .
Safety coefficient : 70 % is safety coefficient from practical experience
rating current of fuse
e.g.,
Condition :
Normal operating current =1.5 A
Ambient temperature 40
: Derating ratio
0.95
rating current of fuse
Normal Operating Current
0.7 x derating ratio
1.5
0.7 x 0.95
105
2.255 < rating current of fuse
