Polymer Tantalum Chip Capacitor Suits High Energy Applications

The TCN PulseCapT Series tantalum solid electrolytic chip capacitors from AVX Corporation is now offered in a polymer electrode version of AVX's industry-favorite, high capacitance, and high energy TLN PulseCapT Series.  Available in the same single, large, low-profile case size (EIA 7361-20) as its parent series, which enables a capacitance range spanning 220 µF to 1500 µF, the TCN PulseCap Series capacitors feature undertab terminations for high volumetric efficiency and high PCB assembly density, in addition to a conductive polymer cathode for reduced ignition and low ESR.  TCN PulseCap Series capacitors are ideal for use as energy bank capacitors in solid state drives (eSSDs) and external hard disk drives (eHHDs), as well as for a wide range of wireless transmitters, including smart meters and smartcards.

"Featuring a low-profile 2 mm height and undertab terminations instead of solder joints on the side of the capacitor body, the new TCN PulseCap Series tantalum chip capacitors enable high volumetric efficiency and PCB assembly density, making them ideal for applications that require both high energy and low profiles, such as eSSD and eHDD devices," said Allen Mayar, product marketing manager at AVX.

Lead-free compatible and RoHS compliant, TCN PulseCap Series capacitors are rated for -55 °C to +85 °C and 6.3 VDC or 16 VDC.  The series also features ±20% capacitance tolerance and 0.1 CV DC leakage current, and is suitable for 3x  reflow solder processing at 260 °C.  Leadtime for the series is 8 to 12 weeks.
