AVX Corporation expanded its TCJ SMD polymer tantalum capacitor series to include the industry's first 1 μF/50 V device. The TCJ series polymer capacitors are suitable for continuous operation with just 20% voltage derating. The TCJ series 50 V range extension meets the demands of DC/DC converter applications that supply circuits in LCD TVs, base stations, rectifiers, switching hubs, routers, line filters, and LED power drivers in PC monitors and new LED-technology TVs.

The tantalum capacitors with conductive polymers are more stable with ambient temperature and applied voltage when compared to multilayer ceramic capacitors (MLCCs). Polymer tantalum capacitors offer several additional intrinsic benefits, such as withstanding high ripple currents and providing low ESR values.

The TCJ Series polymer tantalum capacitors are RoHS-compliant and contain no halogens, which top equipment manufacturers are anxious to eliminate. In addition, the conductive polymer cathode is inherently low oxygen bearing and thus helps provide a reduced ignition failure mode unlike other tantalum technology capacitors.
