Kemet Upgrades Ta Cap Line

Electronic News, Sept 14, 1998

GREENVILLE, S.C.--Kemet Electronics is offering a new case size and CV extension of their ultra-low ESR T510 series tantalum chip capacitor. Typical ESR at 100kHz is 15 milliohms for the 1000 microF 4V capacitor in the new T510E case. "This beats Kemet's previous record low ESR of 30 milliohms in our X case size," the firm claimed. "The T510E has the highest CV and lowest ESR of any molded tantalum capacitor today. Kemet's new E case size has a 7.3mm by 6.0mm footprint and a maximum height of 3.8mm."

Kemet's T510E family utilizes a construction platform that incorporates multiple capacitor elements, in parallel, inside a single package. This technology, combined with Kemet's processing technology, results in a much lower ESR and superior capacitance retention at high frequencies, the firm claimed.

The T510E ultra-low ESR and the high ripple current capability of a maximum of 4 Amps rms target the Switch Mode Power Supply (SMPS) filtering and power decoupling of leading-edge microprocessor applications. The ultra-low ESR will substantially reduce the part count necessary to achieve the total required capacitance and ESR, it was said.

Sample quantities of the T510E are available in a 1000 microF 4V device. A 680 microF 6V will be available in the fourth quarter of 1998. The T510E108K004AS is priced at $1.40 each in full reel quantities of 500 on a 7-inch reel or 2000 on a 13-inch reel. All T510 products are tape and reel packaged per EIA 481-1. u
