The POSCAP product line spans several Series of Solid Electrolyte Chip Capacitors which include the TPE, TQC, TPF, TPSF, TPB, TPC, TPG, and TPU Series. These solid capacitors utilize a sintered tantalum anode and a proprietary high conductivity polymer for a cathode. Panasonic's innovative construction and processing yields one of the lowest ESR level in Polymer Tantalum Capacitor technology, and exhibits excellent performance in high frequency applications. Offering a high volumetric efficiency for capacitance, POSCAP Capacitors are available in various, compact package sizes for a small PCB footprint. Additionally, POSCAP parts demonstrate a high reliability and high heat resistance, making them the ideal Chip Capacitor for digital, high-frequency devices and more.
