The T491B107K010AT with Tantalum Capacitors - Solid SMD 10V 100uF 1311 10% ESR=1.2 Ohms manufactured by Kemet is an electrolytic capacitor. It has the smallest available room-temperature tolerance of 10%, combined with a research grade temperature voltage coefficient of -0.2 % per degree Celsius. It is a long life, solid tantalum capacitor, excellent for use in high performance applications such as military, medical, and industrial. It is comprised of a conductive tantalum powder anode, manganese dioxide cathode, and an encapsulated solid electrolyte. It is capable of handling high temperatures, has good high frequency characteristics, and offers a high capacitance stability. It is also relatively low leakage current and low ESR, while being highly reliable in extreme environmental conditions.
