Vishay Intertechnology Inc. has announced that its tantalum capacitors division is now an approved source for U.S. Defense Logistics Agency (DLA) 20001 wet tantalum capacitors.
The new DLA drawing provides a historically approved aerospace methodology of screening MIL-PRF-39006 tantalum case capacitors with characteristic H shock and vibration. This screening on an individual 
Source: Vishay Intertechnology Inc.manufacturing lot includes 10 cycles of thermal shock and 168 hour constant rated voltage conditioning during the 100% Group A Inspection. Stability at low and high temperatures, 30 thermal shock cycles, and a 1,000 hour rated voltage, 85° C life test are performed on samples during the Group B Inspection.
The DLA 20001 and the M39006/33 series are established reliability products based upon the Vishay T16 series of high reliability wet tantalum capacitors. All offer extended capacitance compared to the more mature CLR79 and CLR81 series, but still maintain the characteristic H ability to withstand 500 g of mechanical shock, as well as 80 g peak of sine vibration, 53.79 g root mean square of random vibration, and 3 V reverse voltage capabilities.
