Vishay – T55 Series: vPolyTan™ Polymer Tantalum Chip Capacitors Offer Ultra Low Equivalent Series Resistance

Offering a wide capacitance range from 3.3μF to 330μF with a voltage rating of 2.5V to 10V, Vishay’s new vPolyTan T55 series of surface mount polymer tantalum molded chip capacitors feature ultra low ESR down to 30mΩ at +25°C and 100kHz.

The low ESR of the T55 capacitors, part of Vishay’s vPolyTan family, is a result of their polymer cathodes, which offer enhanced performance over manganese dioxide devices. In addition, the T55 series offers high ripple current capacity and provides low ESR for enhanced charge/discharge characteristics. These types of capacitors can be used for power management, battery decoupling, and energy storage in computers, tablets, smart-phones, and wireless cards.
