Technology
ISA-PLAN® technology
ISA-PLAN® technology differs from other ISA-WELD® products with respect to the production process, among other aspects. With ISA-PLAN®, the precision resistor elements are etched from films of our resistor alloys. Currently seven ISA-PLAN® SMD product series are available in addition to the conventional 2 and 4-wire current measuring resistors, enabling a wide range of possible applications.
ISA-WELD® technology
In contrast to the manufacturing process for ISA-PLAN® products, the precision and power resistor for the ISA-WELD® procedure consists of solid electron beam-welded composite material made from two copper strips and one of our resistance alloys. This composite material can be adapted to virtually any shape or application in a punching and bending process and therefore allows for the highest possible flexibility within your application design.

Shunt Resistors Applications
Several applications areas for the precision and power resistors are covered by Isabellenhütte. For a more detailed overview, please see this Isabellenhütte video.
Since these properties are influenced both by the resistance material used as well as the design and technology, Isabellenhütte has developed two fundamentally different production technologies: ISA-PLAN® and ISA-WELD®.
