What Is a Polymer Capacitor?
A polymer capacitor is an electronic component designed for storing and releasing electrical energy as needed.
Its unique attribute is its internal makeup; unlike traditional electrolytic capacitors that rely on liquid electrolytes, polymer capacitors employ high molecular weight polymers between the electrodes to facilitate more reliable performance. This design endows them with significant heat resistance and durability, promoting extended periods of stable functioning.
Moreover, the miniaturization of polymer capacitors allows them to maintain the same capacitance in smaller forms, aiding in the miniaturization and increased integration of electronic devices. They also feature low impedance, low equivalent series resistance (ESR), and minimal leakage current, which ensures their stable operation even under high-frequency conditions.
