Extending its T55 series of vPolyTan surface-mount polymer tantalum moulded chip capacitors, Vishay Intertechnology has announced devices in the D and V case sizes and higher voltage ratings from 16 to 25V. Additionally, devices in the A and B case sizes have been enhanced with lower ESR.

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

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 excellent ripple current rating up to 3.9A IRMS and provide low internal resistance for enhanced charge and discharge characteristics.

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 wide capacitance range from 3.3 to 470µF over voltage ratings from 2.5 to 25V, and a capacitance tolerance of ±20%. The devices provide ultra-low ESR from 500 down to 15mΩ at +25°C and 100kHz and operate over a temperature range from -55 to +105°C.

Featuring lead-free terminations, the 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 an MSL of 3.

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