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 2mm makes them ideal 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.

These new PulseCap capacitors complement the AVX BestCap® low ESR devices. In contrast to other large case size, large capacitance devices, PulseCaps are true surface mount devices capable of withstanding lead-free reflow process assembly. They also save more space on a PCB and offer excellent surge robustness.
