Vishay Extends 298D MicroTan Series with Solid Tantalum Chip Capacitors

Vishay Intertechnology Inc. has extended its 298D series of MicroTan solid tantalum chip capacitors to offer a capacitance-voltage rating in the molded 0402 package size. Leveraging the patented MAP (multi-array packaging) assembly technology, the 298D MicroTan capacitors have been extended to offer high capacitance-voltage ranges from 4.7μF-4V to 10μF-4V in the ultra-compact 1.0-mm x 0.5-mm 0402 K-case with a low 0.60-mm maximum profile. Together with the previously released 0603 M-case and 0805 P-case, the series offers a capacitance-voltage range of 0.68μF-35V to 220μF-4V.



By making available a 10μF-4V device in a single 0402 package, the company allows these designers to reduce their capacitor parts count while maintaining superior audio performance not possible with MLCCs, due to their piezoelectric noise. In addition to MP3 players, the 298D tantalum capacitors are suitable for audio filtering and signal processing in mobile phones, digital cameras, and other portable devices, where their ratings enable more stylish end products by requiring less printed circuit board space and reduced product thickness. The devices' rectangular molded case encapsulation is ideal for high-volume PCB assembly, and the special L-shaped facedown terminations offer better contact to the solder pad than traditional facedown style terminations. The samples of the extended 298D series of MicroTan solid tantalum chip capacitors are available now. Production quantities will be available in September 2008, with a lead-time of eight to 10 weeks for larger orders.
