The Littelfuse 477 Series fuses are axial lead and cartridge fuses with time-lag characteristics, commonly used in a wide range of industrial and automotive applications. These fuses provide reliable circuit protection by interrupting fault currents while minimizing nuisance tripping under normal operating conditions. The 5x20mm size makes them suitable for compact designs, and their time-lag feature allows for temporary overloads without interrupting the circuit.
