COTS+ Polymer Tantalum Capacitor Series for Critical Military Systems

AVX Corp. 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.

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.

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 (47µF and 68µF), 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 to 63V and 0.47 to 100µF are currently in development and, upon release, will introduce three new case sizes and a 0.05CV DCL option available on certain codes.
