AVX’s low profile, high capacitance PulseCap™ tantalum capacitors boost transmitter power in solid state drives and wireless pulse applications

Two case sizes of tantalum products are available; case sizes “6” (14.5 x 7.5 x 2.0mm) and “4” (7.3 x 6.1 x 2.0mm) are rated from 1000µF to 3300µF (3.3mF) with a voltage rating of 4V to 10V. A maximum case height of 2mm makes the PusleCap Series 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. “PulseCap, our new addition to the AVX broad tantalum capacitor family, is answering demand for high capacitance devices in a wide range of upcoming applications. The fast wireless data handling in applications like GPS transmitters, GSM communications, Smart Meters, and energy back up for solid state disc in power disruption state are the typical circuits that require capacitance between 1mF to 10mF for safe operation. 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 by offering excellent capacitance volumetric efficiency in low profile cases,” said Dan Lane, marketing manager at AVX.
