AVX introduces the TLN and TCN tantalum capacitors

AVX has developed a termination style for MnO2 (TLN Series) and polymer (TCN Series) tantalum capacitors that reduces the internal construction space by up to 60 per cent.

Undertab terminations, which do not protrude outside of the outline of the case, replace J leads.

This increases volumetric efficiency and allows printed circuit board (PCB) footprint pads to be spaced only slightly wider than the part itself.

The package features a second electrode, which results in a lower self inductance (ESL), enabling a better working frequency range.

The TCN Series version improves ignition resistance.

The smallest devices are available in low profile packaging and are 1mm high.

The planned capacitance range is 22-680uF (+/- 20 per cent) and the working voltage range 4-10V.

The first devices available are the TLN S case (1206, 1.2mm max height) 220uF 4V product and the TCN L case (1210, 1.0mm max height) 150uF 6.3V capacitor.

The devices are suitable for 3x 260C reflow solder processing.

They are suitable for applications requiring high capacitance in a miniature package, particularly consumer products such as handheld devices, mobile phones and MP3 players.

They also suit power line and audio circuit designs.
