AVX Releases COTS+ Polymer Tantalum Capacitor Series for Critical Military Systems

FOUNTAIN INN, S.C. (August 11, 2015) – AVX Corporation, a leading manufacturer of passive components and interconnect solutions, has released a new COTS+ version of its TCR Professional Series polymer tantalum chip capacitors. Designed for use in critical military systems, the new TCB Series COTS+ polymer tantalum capacitors feature conductive polymer electrodes, which enable extremely low ESR and reduce the potential for ignition failure. Additionally, each batch undergoes lot conformance testing and additional reliability level verification in order to provide higher reliability than standard polymer tantalum capacitors. Life tested to 0.1% per 1,000 hours with a 90% confidence level, designed to withstand biased humidity testing at 85°C and 80% of rated humidity for 120 hours, and rated for operating temperatures as high as 105°C, TCB Series capacitors are ideal for: AC/DC power supplies, DC/DC converters, filtering, decoupling, timing circuits, and pulsing circuits.

“Our new TCB Series COTS+ polymer tantalum capacitors provide critical systems design engineers with even lower ESR than typical solid tantalum capacitors, in addition to the high reliability that such applications demand,” said Brian Brunette, high reliability tantalum applications engineer, AVX.  

Currently available in a single case size (AVX Code: D, EIA Code: 2917, EIA Metric: 7343-31), two voltage ratings (10V and 16V), two capacitances (47?F and 68?F), and a single DCL (0.1CV), TCB Series capacitors feature a ±20% capacitance tolerance, are available with two termination finishes (Sn/Pb and 100% tin), and are rated for operating temperatures spanning -55°C to +105°C. TCB Series capacitors rated for 20–63V and 0.47–100?F are currently in development and, upon release, will introduce three new case sizes and a 0.05CV DCL option available on certain codes.

The series is RoHS compliant and lead-free compatible, and lead time for the series is 12 weeks.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
