Complete Guide to Electric Guitar Capacitors | Electric Herald

The value of a capacitor is measured in Farads, but the capacitances we're dealing with for our humble guitar circuits are small and are most commonly measured in Microfarads (µF) or Picofarads (pF). If you're trying to go from one to the other, one picofarad is 1 millionth of a microfarad (ex. 4700pF = .047µF).

TECHNICAL PAPER

Tantalum capacitors are capacitors constructed with tantalum material used to form the anode of the capacitor. Tantalum capacitors are electrolytic capacitors, which means the capacitor is formed by an oxide layer formed on the anode and is thus polarized. A tantalum capacitor includes a tantalum powder anode, a Ta5 oxide layer 2O
