Tantalum Chip Caps Now Available In Z Case Size

Vishay Intertechnology has extended its T55 series of vPolyTan surface-mount polymer tantalum molded chip capacitors with components in the Z case (EIA 7343-19) size. With a 0.1 mm lower height than devices in the standard V case (EIA 7343-20), the capacitors increase package density and enable the design of thinner end products. The devices are optimized for power management, battery decoupling, and energy storage in computers, servers, network infrastructure equipment, solid-state drives, and wireless transceivers.


Offered in J, P, A, B, T (low-profile B — 1.2 mm max), D, V, and Z case sizes, the T55 series features a capacitance range from 3.3 µF to 680 µF over voltage ratings from 2.5V to 63V, and a capacitance tolerance of ± 20 %. The capacitors provide ESR specs from 500 mΩ down to 7 mΩ at +25 °C. Capacitance values up to 1,000 µF and ESR values down to 6 mΩ are in development.
