CONTACT US  |  CUSTOMER SERVICE Tantalum Capacitors Tantalum capacitors are the leading choice when high capacitance is needed in the smallest possible size. KEMET has been the foremost manufacturer of tantalum capacitors for over 50 years, and is constantly introducing new innovations to meet changing demands. Offered in a variety of standard sizes, KEMET tantalum capacitors and are fully RoHS compliant and compatible with modern solder processes including multiple reflow passes. KEMET tantalum capacitors offer many advantages including low ESR, surge current robustness and multiple operating temperature ranges. KEMET also offers a complete line of military and Commercial Off-the-Shelf (COTS) products as well as enhanced testing for space applications. While many applications use surface mount technology, a complete line of through-hole tantalum capacitors are available for down-hole, military and other demanding environments. KEMET’s traditional MnO2 tantalum capacitors consist of a sintered anode of tantalum metal. This anode is porous thus providing increased surface area. An oxide layer is then formed, and this oxide layer becomes the capacitor dielectric. The oxidized anode is impregnated with manganese dioxide to form the cathode. Tantalum polymer capacitors are a newer variation which replaces the manganese dioxide cathode with a solid conductive polymer cathode. KEMET polymer tantalum capacitors are recommended when very low ESR, increased temperature stability or benign failure mode is critical. 2012 Product Selection Guide (New!)
