POSCAP Tantalum Polymer Solid Capacitors Panasonic POSCAP Tantalum Polymer Solid Capacitors achieve stable capacitance at high frequency and temperature and low ESR/ESL. Available in several series that include solid electrolyte chip capacitors (TDC, TPB, TPC, TPE, TPF, TPG, TPSF, TPU, and TQC), the product line utilizes a sintered tantalum anode and a proprietary high-conductivity polymer for a cathode. This construction and processing design yields low ESR levels and reliable performance in high-frequency applications. The capacitors offer a voltage range of 2VDC to 35VDC and a capacitance range of 3.9µF to 1500µF. Panasonic POSCAP Capacitors also feature high reliability, heat resistance, and volumetric capacitance efficiency. They are available in a variety of compact sizes, making them ideal for digital applications, high-frequency devices, and more.
