Determination of the type of fuse
e.g.,
Condition :
Calculating value =2.255 A
,
2.255A < rating current of fuse
Normal operating voltage
: DC 12 V
Following bottom index-table

Inrush current :
Considering inrush waveform & calculate
I2t (A2s) value
Choosing fuse’s I2t (A2s) value > calculate I2t (A2s) value
Considering Ratio of I2t repeat numbers to blowing
Confrim with us
e.g.,
choosing 0603 Fuse
Condition :
1.
Rectangular Wave
, Ip = 4 A
, t = 1 ( ms )
,
Calculate Ip2t = 42 x 1 x 10 –3 (A) = 0.016
(A2s)
2.
Choosing
CF06V2T2R5 ( I2t = 0.055
(A2s) ) ,
3.
Inrush shock : 100,000 times (
0.35 )
Calculating :
1. Choosing fuse’s I2t (A2s) value X Derating ratio > calculate I2t (A2s) value
2. 0.055 x 0.35 = 0.01925
(A2s)
