Vishay Intertechnology Enhances T55 Series of Polymer Tantalum Chip Capacitors With Higher Capacitance to 470 Microfarads and Lower ESR to 25 Milliohms in A, B, and T Case Sizes

MALVERN, Pa., July 01, 2015 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE:VSH) today announced that the company has enhanced its T55 series of vPolyTan™ surface-mount polymer tantalum molded chip capacitors with eight new ratings in the A, B, and T (low-profile B – 1.2 mm max.) case sizes. Taking advantage of Vishay’s market-leading package technology and recent investments in polymer tantalum technology, the Vishay Polytech T55 series now offers significantly higher capacitance and lower ESR for computer, telecom, and industrial applications.

At 2.5 V, capacitors in the B case now offer higher capacitance to 470 µF with ESR of 25 mΩ, in addition to lower ESR of 25 mΩ at a capacitance of 330 µF. At 6.3 V, devices in the A and T case sizes provide improved ESR of 70 mΩ at 100 µF, while B case devices feature lower ESR of 40 mΩ at 33 µF and 35 mΩ at 220 µF. At 10 V, devices in the B case size offer enhanced ESR of 70 mΩ at 47 µF.

The low ESR of the T55 capacitors is a result of their polymer cathodes, which offer greatly enhanced performance over manganese dioxide devices. In addition, the devices offer excellent ripple current rating up to 2.28 A IRMS and provide low internal resistance for enhanced charge and discharge characteristics. The capacitors are optimized for power management, battery decoupling, and energy storage in computers, tablets, smartphones, wireless cards, and solid state drives.

Offered in the compact J, P, A, B, and T case sizes, the T55 series features a wide capacitance range from 3.3 µF to 470 µF over voltage ratings from 2.5 V to 10 V, and a capacitance tolerance of ± 20 %. The devices provide ultra-low ESR from 500 mΩ down to 25 mΩ at +25 °C and 100 kHz and operate over a temperature range of -55 °C to +105 °C with voltage derating above +85 °C.

Featuring lead (Pb)-free terminations, T55 series capacitors are 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 enhanced T55 series devices are available now, with lead times of eight weeks for larger orders.
