KEMET Introduces First-to-Market Tantalum Stack Polymer Capacitors

KEMET Corporation (NYSE: KEM), a leading manufacturer of tantalum, ceramic, aluminum, film, paper and electrolytic capacitors, today introduced its new Tantalum Stack Polymer (TSP) Series capacitors. The TSP Series is the first stack solution in the market that utilizes organic conductive polymer as the cathode plate of the capacitor. TSP Series is targeted for applications requiring high capacitance and very low ESR but with limited board space in the consumer/gaming, computer, medical, military/aerospace, telecommunications, and transportation markets.

“Our new TSP Series surface mountable devices can be specified with a variety of capacitance and performance characteristics by stacking two, three, four, or six standard EIA case size discrete components into just one device, ” said Stanley Garrett, KEMET Technical Product Manager. “These custom combinations result in high capacitance, very low ESR and high ripple current capability in a single footprint, which makes them an ideal solution for applications such as power supplies for a wide range of products.”

KEMET offers this solution with its T540 Commercial Off-The-Shelf (COTS) Series capacitors. However, custom stacks are also available with other KEMET Tantalum Surface Mount Polymer Series products.

TSP Series Technical Information
  • Capacitance values of 66µF to 4080µF
  • Voltage rating of 3VDC-35VDC
  • Surge options available
  • Operating temperature range of -55°C to +125°C
