Jumper resistors are used in a variety of everyday electronic equipment, in switching circuits, or to make a shortcut between circuits. Although ideally jumper resistors have 0 Ω, this is impossible to achieve in the real world, where previously the best jumpers measure in the tens of milliohms. However, in recent years, the increased functionality and larger currents used in the latest electronic devices make it impossible to ignore power losses and voltage drops in jumper resistors, increasing the need for lower resistance values.

ROHM’s PMR jumper series meets this need by utilizing a chip structure and a resistive element composed of a special alloy for superior conductivity. The result is ultra-low resistance – 1/100 that of conventional jumpers – along with minimal power loss and voltage drops, even at large currents. The lineup consists of five models, from the 1608 size (22.4 A) to the 6432 size (63.2 A), in order to meet a wide variety of needs.
