Chip capacitors now offered in D case size

The T55 series of vPolyTan surface-mount polymer tantalum moulded chip capacitors from Vishay has been extended with devices in the D case (EIA 7343-31) size featuring single-digit ESR values from 9mΩ down to 7mΩ, with values to 6mΩ in development.

Previously reserved for larger case sizes, the single-digit ESR values of the capacitors are 3mΩ to 5mΩ lower than those typically found in D case devices.

The results are reduced voltage drops, better frequency response, and higher ripple current ratings up to 5.67A IRMS, which reduces the number of capacitors required on the PCB.

In addition to saving board space, the D case's low 3.1 mm profile enables the design of thinner end products.

Offered in the compact J, P, A, B, T (low-profile B — 1.2 mm max.), D, V, and Z case sizes, the T55 series features a wide capacitance range from 3.3 µF to 1000 µF over voltage ratings from 2.5V to 63V, and a capacitance tolerance of ± 20%.

The devices are optimised for power management, battery decoupling, and energy storage in computers, servers, network infrastructure equipment, solid state drives, and wireless transceivers.

Operating over a temperature range of -55 °C to +105 °C, the capacitors provide low internal resistance for enhanced charge and discharge characteristics.

Featuring lead (Pb)-free terminations, the T55 series is 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 new single-digit ESR capacitors are available now, with lead times of 14 to 16 weeks.
