The introduction of these industry-best capacitance-voltage ratings represents a major breakthrough in volumetric efficiency. For example, until now designers have typically needed to use two 4.7μF-4V capacitors for filtering and minimizing harmonic distortion in MP3 players. By making available a 10μF-4V 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.
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.
