298D MicroTan Series Solid Tantalum Chip Capacitors

Vishay has extended its 298D series of MicroTan™ solid tantalum chip capacitors to offer one of the industry's best capacitance-voltage ratings in the molded 0402 package size.

Leveraging the patented MAP (multi-array packaging) assembly technology, Vishay's 298D MicroTan capacitors have been extended to offer high capacitance-voltage ranges from 4.7 µF-4 V to 10 µF-4 V 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 0.68 µF-35 V to 220 µF-4 V.

The introduction of these capacitance-voltage ratings represents a major breakthrough in volumetric efficiency. For example, until now designers have typically needed to use two 4.7 µF-4 V capacitors for filtering and minimizing harmonic distortion in MP3 players. By making available a 10 µF-4 V device in a single 0402 package, Vishay 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 ideal for audio filtering and signal processing in mobile phones, digital cameras, and other portable devices, where their industry-best 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.
