High Capacitance Tantalum Capacitors Boost Transmitter Power in Wireless Pulse Applications

Thu, 08/05/2010 - 11:13am
AVX Corporation has developed a new range of high capacitance PulseCap™ tantalum capacitors that feature a low profile. The PulseCap tantalum capacitors are designed for applications that require bulk capacitance to boost transmitter power, such as solid state drives (SSDs), PCMCIA/USB wireless express cards, smart meters, GPS transmitters and GSM high-speed wireless data handling.

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 PulseCap 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 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.
