100V and 125V Tantalum Polymer SMD Capacitors

AVX Corporation is expanding its award-winning TCJ Series with two new high-voltage tantalum polymer chip capacitors. Rated for 100V and 125V - nearly twice the rated voltage of similar products currently on the market - AVX's new surface mount, tantalum polymer chip capacitors provide excellent capacitance and low ESR for a broad range of high-voltage applications, including telecommunications equipment, base stations, switching hubs, router and line filters, DC/DC converters in LED TVs and notebook computer power supplies, and a host industrial applications.

AVX's new 6.8µF/100V and 3.3 µF/125V TCJ Series tantalum polymer SMD chip capacitors maintain 20% recommended voltage detracting, which significantly extends the usable voltage range, and are capable of replacing up to two of the highest rated component values in this technology, which provides design engineers with greater flexibility regarding board design. Exhibiting reliability exceeding 1% per 1,000 hours at 85ºC and full-rated voltage, as well as a benign failure mode, which eliminates the ignition failures that can occur in standard MnO2 tantalum technology, the new capacitors are also exceedingly robust.

AVX's 100V and 125V TCJ Series SMD capacitors are rated for use from -55ºC to +105ºC, feature small case sizes (2924 for the 100V and 2917 for the 125V) and low profiles, and are halogen-free in accordance with the criteria for environmentally responsible product design that were recently adopted by several other major electronics manufacturers. Compatible with high-speed pick and place manufacturing processes, the new high voltage capacitors are available on 7" and 13" pure tin reels.

Engineering samples of AVX's new 100V and 125V tantalum polymer SMD chip capacitors are currently available upon request and will be made commercially available in the first quarter of 2013.
