Encapsulated SMT Fuse Provides Intrinsic Safety Protection

The PICO 304 Series surface mount fuse emerges as the first encapsulated surface mount fuse designed for intrinsic safety protection of equipment intended for use in or near hazardous locations and explosive atmospheres and certified to the UL 913 standard. During overcurrent and short circuit fault conditions, the device’s 1-mm-thick encapsulation around the body minimizes the amount of heat produced and contains any sparks or arcs inside the fuse assembly. The fuse is rated for 277V ac/dc with 1,500A breaking capacity, making it suitable for barrier circuits and other circuits separating intrinsically safe circuits from non-intrinsically safe circuits. Available with current ratings from 50 mA to 750 mA, the series is suitable for limiting fault power available in a circuit. The PICO 304 Series Fuse is available in surface-mount packages in 24-mm tape and reel format in quantities of 100 or 800 pieces. Sample requests may be placed through authorized Littelfuse distributors worldwide.
