New Vishay Tantamount tantalum chip capacitor sets industry standard for ESR rating

Vishay Electronic : 08 June, 2001  (New Product)
A new solid tantalum chip capacitor that features the industry's lowest equivalent series resistance rating for its compact size was announced today by Vishay Intertechnology, Inc. The new Vishay Sprague 292D molded leadless chip capacitor is optimized for dc-to-dc power conversion and noise filtering applications in high-end portable systems, handheld electronic products, and hearing aids. Featuring a compact 0805 footprint, the 292D is available in two case options, with either a 1.2-mm (0.047 in.) or 1.55-mm (0.061 in.) maximum height profile, allowing higher density circuit layouts. The new device features wrap-around tin terminations and is surface-mountable, simplifying the design and manufacturing process.

The new Vishay Sprague 292D molded leadless chip capacitor is optimized for dc-to-dc power conversion and noise filtering applications in high-end portable systems, handheld electronic products, and hearing aids.

Featuring a compact 0805 footprint, the 292D is available in two case options, with either a 1.2-mm (0.047 in.) or 1.55-mm (0.061 in.) maximum height profile, allowing higher density circuit layouts. The new device features wrap-around tin terminations and is surface-mountable, simplifying the design and manufacturing process.

Built on Vishay's proprietary Tantamount technology, each 292D capacitor provides an ESR rating that is between 20% to 40% lower than any equivalent device on the market, with ESR values ranging from 3.5Ω to 5.0Ω at 100 kHz. Voltage rating options are 4 WVDC, 6.3 WVDC, and 10 WDVC for devices in both case types, with capacitance levels ranging from 3.3 F to 33 F. Capacitance tolerance options of 10% or 20% are available. The devices are rated for an extended -55C to +85C operating temperature range and a derating temperature of +125C.

Samples of the full 292D product line are available now. Production quantities of specific versions of the 292D capacitors-the 4.7-F at 10 V, and 10-F at 10 V devices-are currently available. Production quantities of the complete 292D series will be available in October 2001 with lead times of six to eight weeks for larger orders.
