AVX Corporation is the first manufacturer qualified to supply polymer electrolytic multianode capacitors for usage in European Space Agency programs. The company’s TCS Series COTS-Plus Solid Polymer Electrolytic Multianode Chip Capacitors are now listed on the ESCC QPL, Detailed Specification 3012/006, as recommended by the Space Components Steering Board.

This series of solid polymer electrolytic multianode capacitors approved to the ESCC QPL has a ruggedised multianode construction with three parallel anodes. The E-case (EIA Metric 7343-43) components measure 7.3mm x 4.3mm x 4.1mm (L x W x H ±0.2) and meet stringent space and weight demands for aerospace equipment. Each lot is subjected to statistical screening, accelerated ageing, and extensive testing procedures to provide long lifetime operation in harsh environments with improved base reliability of 0.5% per 1,000 hours. They display low ESR with values ranging from 12–50mOhm depending on capacitance and voltage. The capacitance range is 22–470μF with a ±20% capacitance tolerance and a voltage range of 6.3–35VDC for operating temperatures extending from -55C to +105C. Customers can also select testing levels B or C and ask for one of three LAT procedures per ESCC regulations to provide appropriate reliability for various space, avionics, defence, industrial, and telecommunications applications.

“AVX has a long history of designing and developing ruggedised, ultra-high-reliability electronic components for mission-critical space applications and is extremely proud to offer the industry’s very first polymer electrolytic multianode capacitors approved for use in European space programs including satellites, missiles, and rovers,” said Chris Reynolds, tantalum technical marketing manager, AVX. “AVX Lanskroun is also ESA qualified to supply TAJ Series single-anode tantalum capacitors per ESCC QPL 3012/001 and TES Series multianode tantalum capacitors per ESCC QPL 3012/004.”
