Polymer cathodes capacitors offer enhanced performance over manganese dioxide types

Vishay's vPolyTan Series surface-mount polymer tantalum moulded chip capacitors are available from TTI Europe in five compact case sizes. Optimized for computer, telecom, and industrial applications, the devices feature ultra-low ESR down to 30mohm at +25C and 100kHz. The low ESR of the capacitors is a result of their polymer cathodes, which offer greatly enhanced performance over manganese dioxide devices. In addition, the T55 series offers excellent ripple current rating up to 1.78A IRMS and provides low equivalent series resistance (ESR) for enhanced charge and discharge characteristics. The capacitors target applications such as power management, battery decoupling, and energy storage in computers, tablets, smart phones, and wireless cards.
