881 Series – Product OverviewWhat significance does it bring to the market?

“881 Series SMT Fuse provides a single fuse solution with 75VDC Current Rating(60A to 100A range) for applications which require high current load

in a limited space.”

§ Higher wattage equipments which require less board space need overcurrentprotection with fuse rating up to 100A

§ 881 Series High Current will help to the Design Engineer to achieve excellent and uncompromised solution to eliminate the paralleling fuses
