Astro 9000 & 5000

Wire Wound Resistors for Measuring and Control Technology

Astro Precision Resistors were developed for critical and demanding

applications, which require a high precision and stable resistance

values. Multi chamber (bifilar) windings secure a low inductance. During

the production process the resistors are trimmed in a special aging

process, which increases the long term stability. Windings and the Epoxy

coating are especially selected to guarantee the best temperature


The radial leaded type Astro 5X and out of the 9X series the Astro 9010R and Astro 9030R have a good space saving design.

Typical applications are measurement devices, laboratory instruments but also current sensing or low power applications.
