As 48 V electric passenger vehicles replace cars with 12 V electrical systems and internal combustion engines, Littelfuse innovates with solutions












Many Japanese automakers use 283B Series Auto Link PAL fuses as original equipment. These bolt-down cartridge fuses withstand extreme temperatures while protecting circuits for alternators and starters. During tests, each of the 283B Series PAL fuses met its performance requirements when receiving 50 % of its ampere rating for 10 000 cycles when current flowed for 5 minutes and was shut off for 10 minutes. The tests were conducted while the temperature of the bolt-down cartridge fuse was 24 °C.
