During overcurrent and short circuit fault conditions, the 1mm-thick encapsulation around the body of the PICO 304 Series surface mount fuse minimizes the amount of heat produced and contains any sparks or arcs inside the fuse assembly, preventing them from being exposed to potentially explosive gases or dust in the environment. This encapsulation eliminates the need to pot or coat printed circuit boards or assemblies, saving production time and money to reduce end-product costs.

The PICO 304 Series is rated for 277V AC/DC with 1500A 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 50mA to 750mA, the series is suitable for limiting fault power available in a circuit, helping to reduce required power ratings and size of downstream components, wiring, and circuit board traces. The PICO 304 Series Fuse is available in surface mount packages in 24mm tape and reel format in quantities of 100 or 800 pieces.
