ISA-PLAN高精度和功率电阻器
ISA-PLAN® technology
Using etching technology, the resistance elements are manufactured from foils of the precision resistance alloys (Manganin®, Zeranin® and Isaohm®), that are mounted electrically insulated on a good heat-conducting metal substrate. The planar structures permit low-inductance design forms and very low thermal internal resistances. An optimized current-density distribution avoids the danger of Hot Spots.
Besides the conventional two and four-wire current-measuring resistors, presently five SMD product families are available. They offer a variety of possible uses, among others, in the fields automotive, power electronics, motive power engineering, energy measurement and medicine technology.
