ASTRO2 precision resistors were developed for critical and demanding applications, which require a high precision and stable resistance value. 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 behaviour. Typical applications are measurement devices, laboratory instruments but also current sensing or low power applications.
