TCJ Series capacitors maintain 20% recommended voltage derating, extends usable voltage range
AVX Corporation, a leading manufacturer of advanced passive components and interconnect solutions, has developed 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, 4.7uF/75V, and 6.8uF/75V ratings, the TCJ Series polymer tantalum capacitors maintain 20% recommended voltage derating, thus significantly extending 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 or burn. AVX puts each TCJ Series capacitor through a stringent aging and screening process to ensure high-performance reliability. The TCJ Series polymer tantalum capacitor exhibits 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 TCJ Series 63V and 75V polymer tantalum capacitors are well-suited for high-voltage applications, including AC/DC converters supplying circuits in LCD TVs, base stations, rectifiers, switching hubs, router and line filters; as well as LED power drivers in PC monitors and LED TVs.
"The new TCJ high voltage polymer tantalum capacitors are ideal for a wide range of applications, as AC/DC converters require both high voltage and high ripple current, which are facilitated by the low ESR offered with conductive polymer technology," said Dan Lane, product manager at AVX. "In addition, LED power drivers have high voltage requirements to provide adequate power for serially-connected diodes, which also require capacitance to function as effectively as possible."
The TCJ Series high voltage tantalum polymer capacitors can solve the problem of audible noise in LCD monitors that use MLCCs, as they can emit noise as a result of capacitance changes due to ambient temperature or voltage fluctuations (piezoelectric effect), causing ripple voltage. Tantalum capacitors are not vulnerable to this problem. These high voltage tantalum capacitors also reduce the overall number of parts required, increasing layout flexibility. The low-profile TCJ Series high voltage polymer capacitors take up less space than comparable aluminum electrolytic capacitors, enabling LCD monitors and similar devices to become even thinner.
AVX has adopted halogen-free compliance for the new series, in accordance with criteria for environmentally responsible product designs recently adopted by other major electronics companies.
