New solid tantalum surface-mount chip capacitors offer ultra-low ESR

16-03-2015 | TTI Europe | Passives

TTI now stocks in Europe Vishay’s latest PolyTan series of surface-mount polymer tantalum moulded chip capacitors in five compact case sizes. Optimized for computer, telecom, and industrial applications, the Polytech T55 series 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 are ideal for use for power management, battery decoupling, and energy storage in computers, tablets, smart phones, and wireless cards.

Offered in the J, P, A, B, and T (low-profile B - 1.2mm max.) case sizes, T55 series devices feature a wide capacitance range from 3.3µF to 330µF over voltage ratings from 2.5V to 10V, and a capacitance tolerance of ± 20%. The devices operate over a temperature range of -55C up to +105C with voltage derating above +85C.

Featuring lead (Pb)-free terminations, T55 series capacitors are RoHS-compliant, halogen-free, offer a moisture-sensitivity level (MSL) of 3 and are compatible with high-volume automatic pick-and-place equipment.
