TCS Series COTS Plus polymer solid electrolytic multianode chip capacitors feature a design consisting of parallel capacitor segments with conductive polymer electrodes in a single package. Combining rugged construction with optimized anode design and materials, the COTS Plus TCS Series delivers very low ESR values (12 mΩ), low leakage current (0.1 CV), high volumetric efficiency (with capacitance ratings at introduction of 470 µF and 1000 µF), high frequency capacitance retention, stable performance characteristics, and a more benign failure mode than traditional SMD electrolytic capacitors under recommended use conditions. Currently available up to 6.3V with development in progress up to 35V rated.


Made to COTS Plus specifications, TCS Series polymer solid electrolytic multianode chip capacitors undergo 100% accelerated age testing, are qualified to MIL-STD-202 with regard to mechanical shock and vibration, and are available with three surge testing options: standard, 10 cycles at 25°C, and 10 cycles at both -55°C and +85°C. Also subjected to AVX’s patented Q-process, which combines maverick part control with statistical screening and process control enhancements to ensure the removal of any components that may experience parametric shifts through customer processing or display instability through operational lifetime, TCS Series COTS Plus capacitors achieve an improved base reliability of 0.5% per 1,000 hours at 85°C and rated voltage with 0.1 Ω/V series impedance.
