Vishay Intertechnology Inc. has launched Polytech T55 series devices with ultra-low equivalent series resistance (ESR) down to 30mΩ at 25°C and 100kHz. The vPolyTan surface-mount polymer tantalum moulded chip capacitors come in five compact case sizes, and are suitable for computer, telecom and industrial applications.

The low ESR of the capacitors is a result of their polymer cathodes, which offer enhanced performance over manganese dioxide devices. In addition, the T55 series offers ripple current rating up to 1.78A IRMS and provides low ESR for enhanced charge and discharge characteristics. The capacitors are optimised 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—1.2mm max.) case sizes, the devices feature a capacitance range from 3.3µF to 330µF over voltage ratings from 2.5V to 10V, and a capacitance tolerance of plus or minus 20 per cent. They operate over a temperature range of -55°C to 105°C with voltage derating above 85°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 moisture sensitivity level 3 (MSL 3).

Samples and production quantities of the T55 series need lead times of eight weeks for larger orders.
