• Manufacturer Part Number: CFS06
• Description: Lead Free Thin Film Chip Fuse
• Manufacturer: American Accurate Components

■ Determination of the type of fuse
■
e.g., choosing 0603 Fuse
◆ Considering Ratio of I
◆ Confrim with us
◆ Considering inrush waveform & calculate I
◆ Choosing fuse’s I
e.g.,
Condition :
Inrush current :
◆ Normal operating voltage : DC 12 V
◆ Following bottom index-table :
◆ Calculating value =2.255 A , 2.255A < rating current of fuse
Condition :
1. Rectangular Wave , Ip = 4 A , t = 1 ( ms ) ,
2.
3.
Calculating :
Suggesting use CFS06V3T2R50 .
