Vishay Intertechnology Extends T55 Series of Polymer Tantalum Chip Capacitors With New Devices in D and V Case Sizes and Higher Voltage Ratings From 16 V to 25 V

MALVERN, Pa., Feb. 04, 2016 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE:VSH) today announced that the company has extended its T55 series of vPolyTan™ surface-mount polymer tantalum molded chip capacitors with new devices in the D and V case sizes and higher voltage ratings from 16 V to 25 V. In addition, devices in the A and B case sizes have been enhanced with lower ESR.

The capacitors released today are optimized for power management, battery decoupling, and energy storage in computer, telecom, and industrial applications. Devices in the larger D and V case sizes are optimized for network equipment, computers, and solid-state drives, while capacitors in the compact A and B case sizes are ideal for tablets, smartphones, and wireless cards. The series’ increased voltage ratings support the 12 V to 20 V range commonly found in supply voltages for computer peripherals.

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 3.9 A IRMS and provide low internal resistance for enhanced charge and discharge characteristics.

Offered in the compact J, P, A, B, T (low-profile B — 1.2 mm max), D, and V 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 25 V, and a capacitance tolerance of ± 20 %. The devices provide ultra-low ESR from 500 mΩ down to 15 mΩ at +25 °C and 100 kHz, and they operate over a temperature range of -55 °C to +105 °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.
