C-Cap Capacitors upgrades PULSE to a whole new level. Made of high purity Metallized polypropylene film with unique technology, it achieves an unparalleled sound quality.

In response to the customer demands, ERSE set out to develop a new type of capacitor with better quality than PULSE X and succeeded in creating the polyethylene capacitance C-CAP. The major difference between the old and new product lies in the European film of supreme quality which is made from extremely pure polyethylene and 99.99% pure aluminum conductor. In the conductor layer, only high purity aluminium is used without any zinc. Heat-treatment methods used over two stages minimizes vibration effect. A type of unique hybrid material is used to make conductor and connected to three separate spraying coating, contributing to the extremely low ESR value and overall improvement in musical sound and performance. The wire being coiled around major diameters results in large surface area and thus connected to conductor perfectly. The wire is manually welded by skilled technicians with audio grade silver welding materials.

Having examined this kind of C-CAP capacitor, many high-end sound engineers have concluded that this type of capacitor delivers high-quality and more beautiful sound, and its price is only half of that of our competitors.
