Vishay Intertechnology Announces New W Case Size for High-Capacitance, High-Voltage, Low-ESR TR3 Molded Tantalum Chip Capacitor

W Case Size Enables Higher Capacitance, Saving Board Space and Lowering Costs

MALVERN, PA--(Marketwire - May 2, 2011) - Vishay Intertechnology, Inc. (NYSE: VSH) today announced the addition of the new W case (EIA 7361) for its popular low-ESR TR3 high-capacitance, high-voltage molded tantalum chip capacitor. Measuring 7.3 mm by 6.0 mm, with a height of 3.45 mm, the new case size allows for capacitance and voltage range expansion beyond the existing A through E case sizes.

Following Vishay's recent release of 63 V and 75 V tantalum capacitors, the introduction of the low-ESR TR3 W case version underscores the company's commitment to offering best-in-class ratings featuring robust designs with maximum voltage and the highest capacitance available in the industry. Vishay will be releasing W case size versions of all its molded tantalum capacitors in the coming months.

By utilizing the W case capacitor, designers can reduce the component count in applications where they previously used multiple components in parallel to achieve large bulk capacitance for energy storage. This saves board space, reduces costs, and improves reliability in telecom base stations, data storage and high-end computing, industrial computers, automotive, and military applications, in addition to medical instrumentation, and more.

Vishay's molded tantalum capacitors offer a package suited to more requirements and applications in all market segments, such as DC/DC output filtering in high-density boards or low-voltage distributed power boards.

The RoHS compliant low-ESR TR3 is suitable for high-volume automatic and manual pick-and-place equipment, and is capable of withstanding lead (Pb)-free soldering reflow conditions.

Samples and production quantities of the low-ESR TR3 molded tantalum capacitor in the W case size will be available in Q2 2011, with lead times of eight weeks for larger orders. Follow Vishay tantalum capacitors at
