Vintage USA-made Cornell-Dubilier Paper in Oil (PIO) Capacitor - .047uF 200V. These are a high quality PIO capacitor. The conductor is made of aluminum foil and the dielectric is oil saturated paper. Similarly constructed to a Sprague Vitamin Q, the capacitors are encased in a metal body with glass-sealed ends. These are New Old Stock, never used with long & strong leads. These capacitors provide excellent sonic characteristics and make great tone capacitors for guitars. .047 is a good value for certain years of Strats or Tele's or the bridge pick-up position in Les Paul's, SG's, ES 335 or other guitars using Humbucker style pickups.
