Chip capacitors now offered in D case size

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 I_RMS, 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.
