Ringtone amplifier tube energy storage capacitor

What is the maximum capacitance for film capacitors?

Film capacitors have a limited capacitance of 'C max to 680 μF'. Basically, film capacitors offer the optimum solution to problems in all areas of application, except for the position of the energy storage/smoothing capacitor, which is typically covered by electrolytic capacitors.

Are film capacitors a good solution for energy storage/smoothing capacitors?

Film capacitors are generally not suitable for energy storage/smoothing capacitors due to their limited capacitance (up to 680 μF). Electrolytic capacitors are typically used in these applications. However, film capacitors offer the optimum solution for other areas of application.

Why are film capacitors preferred over other technologies?

In all other positions, plastic film capacitors are far superior to other technologies both in performance and reliability. Only the position of the energy storage/smoothing capacitor is to be covered by electrolytic capacitors due to the limited capacitance with 'C max to 680 μF' for film capacitors.

What is the best capacitance range for audio applications?

The field of applications in the signal path covers the greatest capacitance range. Higher capacitance values are best covered by the types that are metallized on both sides. Efficient WIMA polypropylene capacitors are available for all the fields of audio applications mentioned before.

Which metallized polypropylene capacitor is best suited for audio applications?

For audio applications, efficient WIMA polypropylene capacitors are available and well-suited. These are metallized on both sides and cover a wide capacitance range, making them ideal for various audio applications in the signal path.

Why do tube amps have small reservoir caps?

There are two main engineering reasons you see small reservoir caps in tube amps: In the Before Time (tm), i.e. when tubes weren't obsolete, a 47uF reservoir cap was an expensive and massive beast.
