Polymer Capacitors Panasonic Capacitors offer a wide range of technologies that can be used in the most demanding applications. OS-CON™ parts are characterized by a long life span and minimal changes in ESR throughout the entire rated temperature range. POSCAP (Tantalum Polymer) parts offer high reliability and high heat resistance, making them the ideal Chip Capacitor for digital, high-frequency devices, and more. The SP-Cap (Aluminum Polymer SMD) line from Panasonic is composed of multiple series that offer an extremely low ESR, a capacitance range up to 560µF, and a voltage range from 2V to 16V, achieving very good noise suppression and transient response. Unlike MLCCs, SP-Caps are not susceptible to temperature drift and DC/AC bias characteristics. The EEH-ZA/ZC/ZK series utilizes the benefits of both electrolytic and aluminum polymer capacitor technologies and combines them, creating a capacitor with low ESR, low leakage current, high ripple current, and smaller case sizes.
