New solid tantalum chip capacitors provide industry's highest available capacitance ratings in low-profile case

Vishay Electronic : 15 February, 2002  (New Product)
Vishay Intertechnology, Inc. today announced the release of two additions to the 592Dfamily of solid tantalum chip capacitors, which nowprovides the industry's highest available capacitance in a low-profile case.
Vishay Intertechnology, Inc. today announced the release of two additions to the 592Dfamily of solid tantalum chip capacitors, which nowprovides the industry's highest available capacitance in a low-profile case.

Designed for noise suppression and capacitive decoupling applications in slim-line products including wireless PCMCIA cards and cell phones, the new 592D devices in low-profile 'X' and 'Y' cases feature exceptionally low equivalent series resistance values, reducing power consumption while enabling thinner and lighter end products.

The new Vishay Sprague 592D devices, part of the TANTAMOUNT product line, feature high capacitance ratings ranging from 1000 F to 2200 F, with standard tolerances of 10% and 20%. The capacitors' ultra-low maximum ESR values range from 0.035 Ω to 0.04 mΩ at +25C and 100 kHz. The X and Y cases feature dimensions of 0.570 in. [14.5 mm] by 0.290 in. [7.37 mm] with maximum height profiles of just 0.078 in. [2.0 mm] and 0.098 in. [2.5 mm], respectively.

Working voltage options range from 4 WVDC to 6.3 WVDC. Maximum current leakage ranges from 60 A to 95 A, and the maximum dissipation factor ranges from 16% to 25% at +25C and 120 Hz. The 592D capacitors feature an operating temperature of −55C to +85C, up to +125C with voltage derating. The new devices are conformal coated and feature two standard 100% tin terminations.

The capacitors' low height profiles enable the design of more compact endproducts for increased convenience and portability. In some applicationsthese high-capacitance devices from the 592Dfamily may be used to replace several capacitors with lower ratings.

Samples and production quantities of the 592D X- and Y-size capacitors are available now in tape-and-reel packaging, with lead times of eight weeks for larger orders.
