Part of the Vishay Sprague TANTAMOUNT® product line, the new capacitors in the 527D series are designed for input/output buffering, dc-to-dc conversion, and noise suppression applications in PDAs, cell phones, LCD display drives, and other handheld and portable appliances.

The new capacitors feature a low-profile P case size with single-sided lead (Pb)-free terminations that enable direct placement under grounding shield applications. The unique uniform geometry of each 527D device aids in accurate placement and more reliable performance.

The capacitors' small dimensions, which measure 0.087 in. by 0.049 in. by 0.039 in. [2.2 mm by 1.25 mm by 1.0 mm], also allow designers to conserve board real estate and add features to lighter, smaller, and more portable electronic systems.

The capacitance ratings for the devices being released today are 10 µF at 10 WVDC and 33 µF at 6.3 WVDC with tolerances of ±10% and ±20% (standard). Tantalum capacitors in the 527D family are conformal-coated and are available in 8 mm and 12 mm tape-and-reel packaging per EIA 481 1 and reeling per IEC 286 3. The new devices in the P case size are specified for an operating temperature range of –55 °C to +85 °C, or up to +125 °C with voltage derating.

Samples and production quantities of the new 572D capacitors are available now, with lead times of 8 to 10 weeks for larger orders.
