Vishay Polytech T55 series polymer tantalum chip capacitors

Vishay Intertechnology has announced the vPolyTan series of surface-mount polymer tantalum moulded chip capacitors in five compact case sizes. Optimised for computer, telecom and industrial applications, Vishay Polytech T55 series devices feature ultralow ESR down to 30 mΩ at +25°C and 100 kHz.

The low ESR of the capacitors is a result of their polymer cathodes, which are said to offer enhanced performance over manganese dioxide devices. In addition, the series offers a ripple current rating up to 1.78 A IRMS and provides low equivalent series resistance (ESR) for enhanced charge and discharge characteristics. The capacitors will be used for power management, battery decoupling and energy storage in computers, tablets, smartphones and wireless cards.

Offered in the J, P, A, B and T (low-profile B - 1.2 mm max) case sizes, the devices feature a wide capacitance range from 3.3 to 330 µF overvoltage ratings from 2.5 to 10 V, as well as a capacitance tolerance of ±20%. The devices operate over a temperature range of -55 to +105°C with voltage derating above +85°C.

Featuring lead-free terminations, the capacitors are RoHS compliant, halogen free and Vishay Green. They are compatible with high-volume automatic pick-and-place equipment and offer a moisture sensitivity level (MSL) of 3.
