    881 Series – Product Overview What 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 overcurrent protection 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
