Tantalum capacitors miniaturised to 0201 case size

February 12, 2015 // By Graham Prophet
AVX has introduced what it believes to be the smallest and lowest profile tantalum capacitor: the sub-millimeter 0201 TACmicrochip.

Measuring 0.6 x 0.35 x 0.35 mm, the 0201 E case TACmicrochip Series SMD tantalum capacitors deliver high CV (0.47 μF / 6.3V) and low leakage (0.01 CV) in an extremely small package, as well as exhibiting all of the standard benefits of tantalum technology, including: inherent immunity to piezoelectric noise and higher stability, higher reliability, and higher temperature performance than comparable MLCCs.

Electrically and mechanically robust, TACmicrochip Series capacitors provide long lifecycle performance for use in miniature, wearable medical devices, audio and power amplifier modules, and as coupling/decoupling capacitors in handheld electronics. The capacitors extend the series' application range to include PCB embedded electronics applications, including near field communication (NFC) systems and smart cards, such as: bank cards, SIM cards, identification cards, and access control cards.

"Thirty years ago, the smallest commercially available tantalum capacitor was the 1206 A case. Since then, AVX has developed and commercialised the first 0805 R case, 0603 L case, and 0402 K case tantalum capacitors … [with] high volumetric efficiency and electrical and mechanical robustness," says AVX. "Capable of being embedded in a PCB, the 0201 E case TACmicrochip capacitor is our latest response to the industry's steady demand for higher volumetric efficiency, [and] an effective solution for designers' lack of board space."

Manufactured using a tantalum wafer process to achieve the high levels of mechanical tolerance required for ultra miniature devices, TACmicrochip Series capacitors feature an enhanced internal construction that eliminates the space-consuming elements of conventional moulded J-leaded tantalum capacitors, including the anode wire, lead frame, and the need for larger wall thicknesses. 0201 TACmicroship Series capacitors are supplied with lead-free, 100% tin terminations and are rated for use in temperatures spanning -55°C to +125°C.
