Cornell Dubilier has received approval by the US Defense Supply Center Columbus (DSCC) as a qualified provider of CLR79 and CLR81 wet-tantalum capacitors. The approval is for M-level reliability and voltage ranges from 25 Vdc to 125 Vdc. 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. Performance highlights compared to solid tantalum capacitors include more capacitance, higher ripple currents, lower ESR and lower dc-leakage current.
Capacitance ranges from 1.7µF to 680µF, voltage from 25 Vdc to 125 Vdc, and operating temperature is -55°C to +125°C. List prices start from $14.00 and lead-time is stock to 12 weeks.
