Vishay Intertechnology has extended its T55 series of vPolyTan surface-mount polymer tantalum molded chip capacitors with new devices in the Z case size.
With a 0.1 mm lower height than devices in the standard V case (EIA 7343-20), the Vishay Polytech 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 the compact J, P, A, B, T (low-profile B — 1.2 mm max), D, V, and Z case sizes, the T55 series features a wide capacitance range from 3.3 µF to 680 µF over voltage ratings from 2.5 V to 63 V, and a capacitance tolerance of ± 20 %.
The capacitors provide ultra-low ESR from 500 mΩ down to 7 mΩ at +25 °C, a result of their polymer cathodes, which offer greatly enhanced performance over manganese dioxide devices. Capacitance values up to 1000 µF and ESR values down to 6 mΩ are in development.
Operating over a temperature range of -55 °C to +105 °C, the capacitors offer excellent ripple current rating up to 5.66 A IRMS and provide low internal resistance for enhanced charge and discharge characteristics. Featuring lead (Pb)-free terminations, the T55 series is RoHS-compliant, halogen-free, and Vishay Green. The devices are compatible with high volume automatic pick and place equipment and offer a Moisture Sensitivity Level (MSL) of 3.
Samples and production quantities of the T55 series capacitors in the Z case size are available now, with lead times of 12 to 14 weeks.
