A new line of axial-lead aluminum electrolytic capacitors from Cornell Dubilier Electronics, Inc. (Liberty, SC) is available for applications that require very high-performance under all operating conditions. The AXLH is a uniquely designed axial-lead electrolytic that has the performance characteristics required for mission-critical circuitry. Continuous ripple current is rated at up to 28 amps RMS (root mean square). The AXLH features a load life rating of 2000 hours at full-rated voltage and 150°C (302°F), and a shelf life of 10 years. Targeted application fields include military, aerospace, off-road vehicles, and infrastructure system electronics. Nine values are available from 470 µF to 4,700 µF, with ratings from 25-V dc to 63-V dc. Maximum ESR (equivalent series resistance) ranges are from 13 to 32 mΩ at 100 kHz. Where other electrolytics may lose performance under very hot conditions, a hallmark of the AXLH is its ability to handle high ripple current at elevated temperature.
