UCQ Aluminum Electrolytic Capacitors Nichicon UCQ Aluminum Electrolytic Capacitors are ideal for audio applications and are especially suitable for high-end audio equipment. This series achieves higher sound quality by using specialized electrolytic paper for audio and by adjusting the density and thickness of the electrolytic paper. These surface-mount capacitors deliver superb audio resolution and reduce the amount of stress a listener might experience. Nichicon UCQ Aluminum Electrolytic Capacitors are AEC-Q200 compliant and feature a 10V to 35V rated voltage range, 4.7μF to 680μF capacitance range, and a temperature range of -55°C to +105°C.
