The components of the capacitor contribute somewhat to the tone of your instrument. Paper-in-oil caps often are termed "musical caps", because they tend to open the tonal range of most pickups. If you have .022uf caps that are paper-in-oil, I''d suggest that you try them and see what they can do for the instrument.

The equivalent circuit for a capacitor is generally modeled as a simple series RLC circuit, which gives a minimum in the impedance curve for the capacitor. When we are operating above the typical digital range of off-the-shelf capacitors that would be used in digital systems, we also have to consider the parasitics of the pads and nearby reference planes.

A capacitor (historically known as a “condenser”) is a device that stores energy in an electric field, by accumulating an internal imbalance of electric charge. It is made from two conductors separated by a dielectric (insulator).

cables should be selected so that 1.5 times the rated capacitor current can be permanently handled. HRC fuses do not protect a capacitor against overload – they are only for short circuit protection.

Advantages of Switched-Capacitor Voltage Converters: High Efficiency: They can achieve high efficiency, especially at low power levels. Scalability: They can be easily scaled to different voltage levels and power ratings. Integration: They can be easily integrated into integrated circuits (ICs).
Even after being turned off for a relatively long period of time, they can still be charged with potentially lethal high voltages. The same applies to all system components and devices which have an electrically conduc-tive connection to the capacitor.
During the operation of thyristor-switched capacitor systems, high DC voltages can occur continuously on the capacitors of compensation systems which are not swit-ched on. These DC voltages must be consi-dered when designing the capacitors and their discharge devices. VI. Risks when a fault occurs circuit power.
