Kemet offers high energy polymer tantalum series

Kemet has introduced its new T545 high-energy polymer tantalum series of surface-mount capacitors. These devices are well suited for applications including SSD (solid-state drives), wireless cards, and GPS systems. "The T545 Series [provides] very high capacitance, low ESR, low profile, and all solid state construction in a surface-mount package," said Per Loof, Kemet's CEO. ??"The T545 Series was developed to deliver the highest energy per cc of any tantalum surface-mount device offered today," stated Dr. Philip Lessner, Kemet's Senior VP, chief technology officer and chief scientist. "This product is subjected to 100% thermal shock and voltage aging [to ensure] long term reliability, while its low profile is designed to fit in the most demanding SSD applications." ??Typical markets include computer, industrial, lighting, medical, defense and aerospace, telecommunications, and transportation. The new devices complement Kemet's TSM and T520 Series. The T545 Series is part of the Kemet KO-CAP (organic capacitor) product family. KO-CAPs are tantalum capacitors with a Ta anode and Ta₂O₅ dielectric. A conductive organic polymer replaces traditionally used MnO₂ as the capacitor's cathode plate. KO-CAPs may also operate at steady-state voltages up to 90% of rated voltage for part types with rated voltages of ? 10 V and up to 80% of rated voltage for part types with rated voltages > 10 V. These products are also available with a tin-lead lead-frame finish, surge-current testing options, and standard or low ESR. Kemet datasheet deeplink
