Polymer tantalum chip capacitors for high energy applications

December 16, 2013 // By Graham Prophet
TCN PulseCap capacitors have a capacitance range spanning 220 - 1500 μF, exhibit high volumetric efficiency and low ESR, and are ideal for use in eSSDs, eHHDs, and wireless transmitters

AVX's TCN PulseCap Series tantalum solid electrolytic chip capacitors are a polymer-electrode version of the company's high capacitance, high energy TLN PulseCap Series. Available in the same single, large, low-profile case size (EIA 7361-20), the TCN capacitors have undertab terminations for high volumetric efficiency and high PCB assembly density, in addition to a conductive polymer cathode for reduced ignition and low ESR. Use them as energy bank capacitors in solid state drives (eSSDs) and external hard disc drives (eHHDs), as well as for a wide range of wireless transmitters, including smart meters and smartcards.

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 0.1CV DC leakage current, and is suitable for 3x reflow solder processing at 260°C.
