Tantalum Capacitors Suited for Boosting Transmitter Power in Wireless Express Cards

AVX Corporation has developed a high capacitance PulseCap™ capacitor in a low profile package. The capacitors are designed for applications such as PCMCIA/USB wireless express cards where bulk capacitance is needed to boost transmitter power. These large case size tantalum products are rated at 2200µF (2.2mF) / 6.3V. A maximum case height of 2 mm makes them appropriate for reduced-height applications. The ‘undertab’ termination style — where traditional ‘J’ leads are replaced by terminations that do not protrude outside of the outline of the case — increases volumetric efficiency and allows parts to be positioned very closely together, delivering significant space savings. PulseCap devices are RoHS compatible and capable of withstanding a soldering profile of 3x reflow at 260°C. Operating temperature range is -55°C to +125°C. Other applications include wireless data cards, metering and sensors.
