Dielectric loss factor

The dielectric loss factor of a capacitor shows that the insulation between the two poles is insufficient. A capacitor has an ohmic component that causes it to heat up at high current levels. However, not all capacitors react the same way. There are great differences in the dielectric loss factor. Metallised capacitors, for example, have a lower dielectric loss factor than electrolytic capacitors. Since a poor dielectric loss can have a negative effect on the sound properties, it is important to use low-loss capacitors wherever possible. However, if the dielectric loss factor is included in the sound tuning activities, changing one capacitor for a different one with a lower loss factor will not necessarily mean the sound properties improve.
