63V and 75V SMD polymer tantalum capacitors for high voltage application

May 22, 2012 // By Julien Happich
AVX has developed what the company claims to be the industry's first 63V and 75V single-anode tantalum polymer capacitors.

Part of the TCJ Series polymer tantalum capacitors, these new surface mount devices (SMDs) deliver high capacitance, high voltage and low ESR values in a small case size. Available in 1uF/63V, 4,7uF/63V, 10uF/63V and 4.7uF/75V, 6.8uF/75V rated voltages, the TCJ Series polymer tantalum capacitors maintain 20% recommended voltage derating, thus significantly extending the usable voltage range. This unique combination brings polymer tantalum technology to a number of new applications and enables the development of a new generation of power supplies.

The TCJ Series high voltage capacitors feature reduced ignition failure mode, making them more robust and less likely to overload. The TCJ Series polymer tantalum capacitor maintains high reliability exceeding 1% per 1000 hours at 85ºC and full-rated voltage. In addition, SMD technology provides the advantages of small case sizes and low profiles for high-speed pick and place during manufacturing. The devices are free of piezo issues related to use of MLCC ceramic capacitors in circuits such as backlight controllers in LCD monitors and displays.They also reduce the overall number of parts required ,due to its lower ESR, increasing layout flexibility.
