New ELNA/Cerafine (ROA) series/audio capacitor 22UF/25V/
Spot for long feet
CerafineSeries of capacitors specially designed for audio, using OFC oxygen-free copper feet, very low distortion (third harmonic distortion -120dB), very small tangent loss, using the technology of pouring ceramic powder in the electrolyte, the powder diameter is controlled within Between 0.1-0.15 microns. According to the manufacturer, this technology has two major benefits: First, it increases the damping effect on external vibrations. 2. When the ceramic powder is charged and discharged in the capacitor, it will adsorb the negative ions in the electrolyte and become more active ion groups. A thin film is formed on the surface of the anodic oxide film, which greatly improves the response speed to the signal and makes the sound quality It is more pure and transparent, but its price is large and expensive. Sound: The sound is softer, the middle frequency is warm and soft, and the high frequency is more gorgeous!
Capacity: 22U/25V
