Original Press Release:

Vishay Releases New Series of Application-Specific Pulse Capacitors for Wireless Modems with Industry-High Capacitance to 2,200 µF in Three Case Sizes

New 592W Solid Tantalum Chip Capacitors are First to Feature Capacitance of 750 µF at 10 V in 7.5 mm by 6.3 mm M Case

MALVERN, PENNSYLVANIA - Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of solid tantalum chip capacitors featuring a robust design specific for pulsed operation in wireless modems. The 592W devices feature industry-high capacitance from 330 µF to 2200 µF over a voltage range of 6.3 V to 10 V in three case sizes offering low profiles of 1.6 mm and 2.0 mm.

The capacitors released today feature stable electrical performance over temperature, pulse repetition interval, and voltage. The devices will be used as bulk capacitors for pulse loads in PA circuits and energy storage in wireless modems, solid-state drives, and mobile stereo audio.

The 592W capacitors are offered in the compact C (7.1 mm by 3.2 mm), M (7.5 mm by 6.3 mm), and X (14.5 mm by 7.37 mm) case codes. They are the first such devices to feature a capacitance of 750 µF at 10 V in the M case. With its small footprint and high capacitance, the 592W series reduces the component count and saves PCB space.

100 % surge current tested, the RoHS-compliant capacitors feature an operating temperature range of - 55 °C to + 125 °C (with voltage derating) and ± 20 % standard capacitance tolerance.

Samples and production quantities of the 592W series capacitors are available now, with lead times of eight to 10 weeks for larger orders.
