Fusistor, pico fuse, chip fuse, micro chip, resistor fuse. Littel fuse. Characteristics and operation of the protection device. What is it? How does it work? Green resistor. Littelfuse. Fusistor or pico fuse, like the glass fuse, is a protection device against excessive currents. The difference is that the first uses a resistance system to dissipate excess energy, reestablishing its standard operation while the current normalizes. The glass fuse becomes unusable when exercising protection; it literally burns, breaking the metal filament.
