AVX has revealed that the European Space Agency have approved their high-reliability TES Series low ESRLow Equivalent Series ResistanceLow Equivalent Series ResistanceLow Equivalent Series Resistance tantalum chip capacitors. Having received full ESA qualified part list qualification approval in accordance with the European Space Components Coordination specification ESCC3012/004, the TES Series tantalum SMDDiscrete miniature capacitors which are packaged without leads and fastened directly to foil patterns. chip capacitors offer higher capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. and lower ESRLow Equivalent Series Resistance values than any existing ESCC-qualified tantalum devices designed for use in aerospace applications.
Tomas Zednicek, Technical Marketing Manager at AVX, comments: "TES Series tantalum capacitorsThe tantalum capacitor distinguishes itself from other capacitors in having high capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. per volume and weight. Relative to other electrolytic capacitors, tantalum capacitors have low resistance, low leakage, and can operate in higher temperature environments, but non-electrolytics are even better in these regards., which were previously qualified to the ESA's European Preferred Parts List (EPPL2), provide the lowest ESRLow Equivalent Series Resistance and highest CV values of any existing QPL-qualified space component, as well as feature a high-reliability design without compromise."
Available in five miniature sizes spanning 3216-18 to 7343-43 and in single and multianode cases, the TES Series capacitors can be downsized. This enables design engineers to realise significant reductions in both payload and physical space, which are extremely beneficial in aerospace applications.

The vertical multianode TES Series parts are available in 7343-31 sizes, whilst the mirror multianode TES Series parts, which fully halve ESRLow Equivalent Series Resistance values, are available in 7343-43 sizes. Available with either ±10% and ±20% tolerances, the TES series offers three screening levels (B (x-ray), C, and non-ER for non-flight parts) and three ESCC lot acceptance testing levels.
Supplied in bulk or on 4" or 7" tape and reel upon request, the TES Series tantalum SMDDiscrete miniature capacitors which are packaged without leads and fastened directly to foil patterns. chip capacitors were produced in AVX's ESA-qualified manufacturing plant in the Czech Republic. Featuring SnPb terminations, the lead time for the series is 24 to 36 weeks depending upon LAT level requirements.
