251/253 Series PICO® II Very Fast-Acting Fuses

Littelfuse 251/253 Series PICO^® II Very Fast-Acting Fuses are designed to meet an extensive array of performance characteristics in a space-saving subminiature package. These fast-acting fuses operate at -55°C to 125°C temperature range and at 0.062A to 15A current rating range. The 251/253 series fuses are small and feature low-temperature re-rating. These fuses are ideal for flat–panel display TVs, LCD monitors, LCD backlight inverters, office machines, power supplies, audio/video systems, lighting systems, and medical equipment.
