Linear Technology Announces QML Class V Standard Microcircuit Drawings for Popular Radiation Hardened Components

    Linear Technology Corporation on October 26, 2016, announced Qualified Manufacturer List (QML) Class V Standard Microcircuit Drawings (SMD) for some of the most widely used Radiation Hardened (RH) components. Part types now available to QML Class V are RH1013 and RH1014 op amps; RH1498 and RH1499 precision rail-to-rail op amps; and RH1009 and RH1021-10 voltage references.

    QML Class V components are intended for use in the most demanding space flight applications and must meet the performance, quality and reliability requirements defined in MIL-PRF-38535. By choosing QML Class V components, users are guaranteed that the component manufacturers’ test methods and quality procedures meet the exacting standards of the U.S. Government Qualifying Activity program.

    Consequently, the use of QML Class V components is preferred by spacecraft prime contractors. This can lower program costs by simplifying the procurement process, reducing component documentation, and may no longer require performance of destructive physical analysis using flight grade components. Compliance to Radiation Hardness Assurance (RHA) ensures that Linear Technology has performed Radiation Lot Acceptance Tests on each manufacturing lot, so manufacturers no longer need to commission their own Total Ionizing Dose testing, providing further cost and time savings.

    Additional Linear Technology RH products are planned for release to QML Class V. For more information, pricing and availability for Linear’s complete line of SMD, Rad Hard, Space and Military components, please contact your local sales office or
