Vishay Intertechnology announced that it has extended its 298D series of MicroTan solid tantalum chip capacitors to offer an industry-best capacitance-voltage rating 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.

AVX Corporation has developed a family of fused tantalum capacitors that feature an internal fuse to protect against short circuits and damaging high DC leakage currents. Designated the TAW Series, the tantalum capacitor will remove itself from the circuit and into "fail safe mode" when the internal fuse exceeds the current limit.
