Rohm has announced the development of the PMR series of low ohmic jumper resistors featuring reduced conduction resistance of 0.5mΩ maximum and high rated current. The company says that its jumpers utilise a chip structure and a resistive element composed of a special alloy for good conductivity. The five models available are PMR03EZPJ000, PMR10EZPJ000, PMR18EZPJ000, PMR50HZPJ000, and PMR100HZPJ000. They have sizes of 1608, 2012, 3216, 5025 and 6432mm, respectively. The jumpers are compatible with currents of 22.4, 31.6, 38.7, 44.7, and 63.2A, respectively. They have good resistance to over-current and pulse loads. The jumpers are lead-free and surface mounting is possible by replacing jumper leads.
