Cornell Dubilier Approved for Level R, MIL-PRF-39006 Wet Tantalum Capacitors

Both types have hermetically sealed cylindrical tantalum cases with a special double-seal construction.

Liberty, SC (July 2006) — Cornell Dubilier acknowledges receipt of approval by the Defense Supply Center Columbus (DSCC) as a qualified provider of CLR79 and CLR81 wet tantalum capacitors. The approval is for R-level reliability (.01%/1000 h) and voltages from 25 Vdc to 125 Vdc. The R level approval is in addition to the M and P levels which were received in 2004. CLR79 is listed as MIL-C-39006/22 and CLR81 as MIL-C-39006/25. The Type CLR79 is similar to Cornell Dubilier's commercial Type TAT, and CLR81 is similar to Cornell Dubilier's Type TAX.

Both types have hermetically sealed cylindrical tantalum cases with a special double-seal construction. Types CLR79 and CLR81 are widely used in avionic applications because of their high energy density and ability to withstand the rigors of outer space. These types offer up to 15 times the capacitance of a solid tantalum capacitor in the same size and voltage.

Capacitance ranges from 1.7 µF to 680 µF, voltage from 25 Vdc to 125 Vdc, and operating temperature is -55°C to +125°C. List prices are from $14.00 and lead time is stock to 12 weeks.
