Newly Extended Vishay Capacitor Series Offers Reduced Voltage Drops, Better Frequency Response, Higher Ripple Currents Ratings Up to 5.67A IRMS — and ESR Down to 7mΩ in the D Case

New Yorker Electronics has announced the release of the extended Vishay Polytech T55 series of vPolyTan surface-mount polymer tantalum molded chip capacitors. The new devices in the D case (EIA 7343-31) size features single-digit ESR values from 9mΩ down to 7mΩ, with values to 6mΩ in development.

Previously reserved for larger case sizes, the devices’ single-digit ESR values of are 3mΩ to 5mΩ lower than those typically found in D case devices. This results in reduced voltage drops, better frequency response and higher ripple current ratings. These tantalum capacitors also reduce the number of capacitors required on the PCB, and with the D case’s low 3.1mm profile, they enable the design of thinner end products.

This series gets better frequency response and higher ripple current ratings up to 5.67A IRMS. They provide low internal resistance for enhanced charge and discharge characteristics.

The extended versions now boasts a capacitance range of 3.3μF to 1000μF, a voltage rating of 2.5VDC to 63VDC and a tolerance of ±20 %. Compatible with “high volume” automatic pick and place equipment, the T55 Series is ideal for such applications as power management, battery decoupling and energy storage in computers, servers, network infrastructure equipment, solid state drives and wireless transceivers.

Case sizes range from 1.6mm x 0.8mm x 0.8mm up to 7.3mm 4.3mm x 2.8mm. Depending on the case size, it has a maximum permissible power dissipation of between 0.05W and 0.225W at ≤ +45°C in free air.
