Inorganic passivation is virtually a hermetic seal. This gives the RG series unsurpassed reliability even when compared to our own RR series which already exhibits very high reliability characteristics. The new passivation technology enhances the performance, as well. The RG series offers better tolerance, TCR and a higher operating temperature range than RR series. The RR series is sufficient for regular applications, but for applications that require higher accuracy and the utmost environmental protection, the RG series is the answer.
