SONIQS PXX Polypropylene

Specially developed to meet the needs of the speaker builder, the 'SONIQS' PXX capacitors are wound using a 6µm (250Vdc rated) polypropylene film. After resin coating and heat treatment the insulated copper terminals are hand soldered to give the best possible connection.
The inherently low dissipation and dielectric absorption factors of polypropylene allied with an excellent mechanical stability results in a highly detailed sonic performance. The construction also results in a low self-inductance and ESR and the devices are highly stable with regard to temperature and frequency.
