Accu-Guard® II Low Current Miniature 0402 Size Thin-Film Fuses The new F0402G Accu-Guard® series of fuses is based on thin-film technology which allows precise control of the component electrical and physical characteristics that is not possible with standard fuse technologies. The Accu-Guard Low Current series encompasses the lowest current ratings in a compact 0402 package and features LGA terminations. ELECTRICAL SPECIFICATIONS Operating temperature: -55ºC to +125ºC Current carrying capacity: -55ºC to -11ºC 107% of rating -10ºC to +60ºC 100% of rating +61ºC to +100°C 85% of rating +101ºC to +125°C 80% of rating Rated voltage: 32V Post-fusing resistance: >1MΩ Current Resistance Voltage Drop Fusing Current Pre-Arc I 2t ColorPart Number Rating @0.1 x I RATED @IRATED (within 5 sec) @10xI RATED CodeA Ω (max.) mV (max.)
