Measuring just 0.6x0.35x0.35mm, AVX has claimed that the sub-millimetre 0201 TACmicrochip series is the world’s smallest and lowest profile tantalum capacitor. The 0201 E case TACmicrochip capacitors provide standard tantalum technology benefits, including inherent immunity to piezoelectric noise, as well as higher stability, higher reliability and higher temperature performance than comparable MLCCs.

Electrically and mechanically robust, TACmicrochip Series capacitors provide a long lifecycle performance suited for use in miniature, wearable medical devices, audio and power amplifier modules and as coupling/decoupling capacitors in handheld electronics. The 0201 E case TACmicrochip capacitors extend the series’ application range to include PCB embedded electronics applications, including NFC systems and smart cards, such as: bank cards, SIM cards, identification cards and access control cards.

The TACmicrochip series SMD tantalum capacitors deliver a capacitance of 0.47μF, a voltage of 6.3V and low leakage of 0.01A.

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 molded J-leaded tantalum capacitors, including the anode wire, lead frame,and the need for larger wall thicknesses.

Mitch Weaver, Technical Staff Member, AVX, commented: “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, all of which have been enthusiastically embraced by the consumer electronics industry for their high volumetric efficiency and impressive electrical and mechanical robustness. 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, an effective solution for designers’ chronic lack of board space and a testament to AVX’s dedication to continually pushing past the limits of current manufacturing technology.”

The 0201 TACmicrochip series capacitors are supplied with lead-free, 100% tin terminations and are rated for use in temperatures from -55 to +125°C. Lead time for the series is 10-14 weeks.
