Vishay Intertechnology Inc. has extended its T55 series of vPolyTan surface-mount polymer tantalum moulded chip capacitors with additional devices in the D and V case sizes. Providing higher voltage ratings from 16V to 25V, the latest devices have been enhanced with lower ESR, added the company.

The capacitors are optimised for power management, battery decoupling and energy storage in computer, telecom and industrial applications. Devices in the larger D and V case sizes are optimised for network equipment, computers and solid-state drives, while capacitors in the compact A and B case sizes are intended for tablets, smartphones and wireless cards. The series' increased voltage ratings support the 12V to 20V range commonly found in supply voltages for computer peripherals.

T55 series

Vishay revealed that the low ESR of the T55 capacitors is a result of their polymer cathodes, which offer greatly enhanced performance over manganese dioxide devices. In addition, the devices offer exceptional ripple current rating up to 3.9A IRMS and provide low internal resistance for enhanced charge and discharge characteristics, added the company.

Offered in the compact J, P, A, B, T (low-profile B, 1.2mm max), D and V case sizes, the T55 series features a capacitance range from 3.3?F to 470?F over voltage ratings from 2.5V to 25V, and a capacitance tolerance of 20 per cent. The devices provide ultra-low ESR from 500m down to 15m at 25C and 100kHz, and operate over a temperature range of -55C to 105C.

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 a Moisture Sensitivity Level (MSL) of 3.

Samples and production quantities of the extended T55 series are available with lead times of eight weeks for larger orders.
