Capacitors

Capacitors are passive devices that are used in almost all electrical circuits for rectification, coupling and tuning. Also known as condensers, a capacitor is simply two electrical conductors separated by an insulating layer called a dielectric.  The conductors are usually thin layers of aluminum foil, while the dielectric can be made up of many materials including paper, mylar, polypropylene, ceramic, mica, and even air. Electrolytic capacitors have a dielectric of aluminum oxide which is formed through the application of voltage after the capacitor is assembled. 

Characteristics of different capacitors are determined by not only the material used for the conductors and dielectric, but also by the thickness and physical spacing of the components. 

All capacitors have a voltage rating that should not be exceeded. Exceeding the voltage rating of a capacitor can cause it to fail. As the voltage rating increases, the dielectric must be thicker, making high-voltage capacitors larger per capacitance than those rated for lower voltages.

C-MCS-100Capacitor - MusiCap, 100V, Film & Foil Polypropylene

Critical loudspeaker crossovers deserve to have a transparent product specific to the application. Speaker MusiCaps, with their thicker leads, are a revelation in well-designed crossover networks. While a fully MusiCap-ed crossover is supreme, just installing MusiCaps in the tweeter circuit will reveal much additional detail and nuance. Many prominent high-end loudspeaker manufacturers have been using MusiCaps in their top models for years.

C-MCCD01-1000Capacitor - MusiCap, .01µF, 1000V, Polypropylene, Coupling

MusiCaps are constructed using separate layers of premium foil and polypropylene films, rather than the vapor deposited, metallized film used by most other manufacturers. Film-plus-foil construction requires more costly materials and result in MusiCaps being approximately 100% larger than typical metallized-film capacitors, yet the benefits are immediately discernible. MusiCaps provide a dramatic improvement in clarity, focus and dynamics when used in critical new designs, as an upgrade to existing tube or solid-state components, or in musical instruments.

C-MCCD47-600Capacitor - MusiCap, 600V, Polypropylene, Coupling
MusiCaps are constructed using separate layers of premium foil and polypropylene films, rather than the vapor deposited, metallized film used by most other manufacturers. Film-plus-foil construction requires more costly materials and result in MusiCaps being approximately 100% larger than typical metallized-film capacitors, yet the benefits are immediately discernible. MusiCaps provide a dramatic improvement in clarity, focus and dynamics when used in critical new designs, as an upgrade to existing tube or solid-state components, or in musical instruments. (Stranded, 22 gauge silver-plated copper leads with Teflon insulation.) Made in the USA. The dimensions of the 600 Volt MusiCap capacitors are as follows:
