KEMET Releases Low DC Leakage MnO2 Series Tantalum Surface Mount Capacitors

August 01, 2011 by Jeff Shepard

KEMET Corp. announced the release of its low DC leakage MnO2 Series tantalum surface mount capacitors. This option is well suited for decoupling and filtering in industrial and automotive high end applications.

"KEMET’s T489 Low DC Leakage Series provides 25% lower leakage than standard MnO2 tantalum capacitors, with better reliability, as well as low ESR options," said Stanley Garrett, KEMET Technical Product Manager. "This device was developed in response to applications requiring low DC leakage current in the circuit, such as tire pressure monitoring sensors and various wireless sensor applications."

The T489 standard terminations are available in 100% matte tin and provide excellent wetting characteristics and compatibility with today’s surface mount solder systems. Tin/lead (SnPb) and gold-plated terminations are available upon request for any part number. This system provides perfect compatibility with all tape-fed placement units.

T489 Series features include: DC leakage at 0.0075CV; 0.50%/1000hrs, 85°C, rated voltage; low ESR options available; automotive Grade available; meets or exceeds EIA standard 535BAAC; symmetrical, compliant terminations; RoHS compliance and lead-free terminations; capacitance values of 0.1 to 470µF; tolerances of ±10% and ±20%; voltage rating of 6.3–50Vdc; and an operating temperature range of -55 to +125°C.
