TA-I TECHNOLOGY CO., LTD ★ Selection Guideline of Fuse: ■Checklist of selection factors ◎Normal operating current ◎Normal operating voltage ( AC or DC ) ◎Ambient Temperature ◎Overload current and length of time in which the fuse must open . ◎Type of fuse ( SMD or Tube ) and physical size limitation ( 0603 or 1206 ) ◎Agency Approval required ( e.g., UL248-14 ) ■ Normal operating current e.g., Rectangular Wave, If I p = 1.5 A , Normal operating current = 1.5 A
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 Ambient temperature Safety coefficient
TA-I TECHNOLOGY CO., LTD ■ 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 : Suggesting use CFS06V3T2R50 .
