Precision and power resistors
As one of the leading providers worldwide we are producing first-class precision and power resistors in the field of low resistance load for various applications. When it is about getting the most precisely measured results, in a minimum of space, we represent the ideal partner. This can be offered by our advanced shunt-technology. Thanks to our decades of experience and profound knowledge we are producing the highest quality precision resistors. Our series comply with the RoHS-Directives as well as the AEC-Q200-specifications. In some cases, they’re also qualified for use in space.
Precision that comes from within.
Standard modules or highly durable precision resistors – our products meet the highest requirements for temperature coefficient (TC), thermal EMF, long term stability, inductance and load capacity. Due to the fact that these properties are influenced by the resistance material as well as by type and technology, we have developed two completely different manufacturing technologies: ISA-PLAN® and ISA-WELD®.
ISA-WELD® resistors are stamped from solid electron-beam welded composite materials consisting of copper in combination with one of our resistance alloys, e.g. MANGANIN®, ZERANIN®, ISAOHM®, NOVENTIN® or Aluchrom. This process is very flexible and offers a wide range of options in terms of both, design and production. The resistors can be adapted by means of stamping and bending to suit almost any shape and application. Further benefits are given by the comparably low input resistance of the copper terminals, their high thermal conductivity respectively their heat storage capacity and the resulting current density and heat dissipation within the shunt. ISA-WELD® shunts are suitable for extremely low ohmic values (below 5 mOhm). They are available as SMD- or busbar assembly.
