Littelfuse makes the tiny, unglamorous parts that keep electricity from destroying electronics — fuses, TVS diodes, relays, switches, sensors and power semiconductors. It sits between raw silicon and metals and almost every end market (cars, factories, the grid, data centres, appliances), and it has grown for decades by buying its way into adjacent protection niches (IXYS, Carling, C&K, Basler).
