VISHAY INTERTECHNOLOGY, INC. The use of polymer tantalum capacitors is growing rapidly in the commercial, industrial, and automotive industries, and is likely the future of small size bulk capacitance. The avionics, military, and space (AMS) market has been slower to adopt polymer tantalum technology.
Additionally, the voltage derating of polymer tantalums is much lower (as shown in Fig. 1) and the ESR is roughly an order of magnitude lower than standard MnO2 tantalum capacitors by comparison, while still providing excellent capacitance stability over temperature and voltage.
Molded chip polymer tantalum capacitors encase the element in plastic resins, such as epoxy materials. The molding compound has been selected to meet the requirements of UL 94 V-0 and outgassing requirements of ASTM E-595 (see Fig. 1). After assembly, the capacitors are tested and inspected to assure long life and reliability.
Mechanically, the stacking of T54 polymer capacitors allowed our customer to significantly increase the capacitance density available for the given PCB area. Our custom solution took advantage of the height available by minimizing part placement on the linear plane and provided 35.6 % space savings.
With stacks, multiple capacitors are clamped together in parallel arrays. As the capacitors are configured in parallel, the capacitance increases with a reduction in ESR. The stacked options are 1 x 2 (one capacitor wide, two tall), 1 x 3, 2 x 2, 2 x 3, and 3 x 2. Ratings available range from 130 μF at 75 VDC to 2800 μF at 16 VDC.
Vishay offers several options for stacked polymer capacitors, including a two-stack, three-stack, four-stack, and six-stack, as shown in Table 1. Fig. 2 shows the current available capacitance values and corresponding stack configurations. Contact your local Vishay sales representative for availability and sampling.
