Stackpoleâs MCJ High Current Jumpers for High Power Density Electronics
11 March 2026 Stackpole says its MCJ Series is a high current SMD jumper chip resistor designed to deliver exceptionally low resistance and high current capability in standard chip sizes. Featuring a solid metal element construction, the MCJ Series supports current ratings from 8 amps in 0201 packages up to 122 amps in 2512 sizes, with overload capability reaching 244 amps for improved tolerance to surge and inrush conditions. Chip sizes 0402, 0603, and 0805 are also AEC compliant.
Conventional thick film jumpers are typically limited to approximately 3 amps, with high-current versions reaching only about 10 amps. In contrast, the MCJ Series can accommodate a significantly higher current level, addressing the growing demands of modern high power density electronics where available board space continues to shrink.
By combining high current handling with compact SMD footprints, the MCJ Series allows designers to replace larger jumper solutions with smaller components. This enables reduced PCB area, greater layout flexibility, and more efficient use of available space. The result is improved power density and dependable performance in demanding applications.
Pricing for the MCJ Series varies by size. For detailed or volume pricing, contact Stackpole or one of its authorised distribution partners. Sizes 0201, 0402, 0805, 1206, and 2512 are currently in stock.
