In both cases the capacitors should have low leakage current and have adequate precision. The best choices for feedback capacitors are class 1 ceramic capacitors, polystyrene film capacitors, and for high temperature applications, polycarbonate film capacitors.
Low-level energy storage in peak detector and sample-and-hold circuits should employ polystyrene capacitors because of their low dielectric absorption characteristic. Large energy storage requirements can be satisfied by aluminum electrolytic capacitors or supercapacitors. Capacitors are used to form negative feedback in op amp integrators.
Aluminum electrolytic and tantalum electrolytic capacitors are common choices for power conditioning. Pulsed power capacitors are energy discharge capacitors designed to provide high peak discharge current, high energy density, low inductance and low equivalent series resistance.
In choosing coupling capacitors for audio frequency work, aluminum electrolytics or tantalum capacitors may be a good option. Niobium electrolytic capacitors may suit low-voltage applications (10 volts or less) with safety concerns. Higher voltage applications and operation at higher frequency may require Class 2 ceramic capacitors.
Capacitance values for fixed capacitors can range from picofarads to frads, depending on the specific type and application. Voltage ratings may also vary with some models being capable of handling thousands of volts.
Class 1: offers high stability and low losses for resonant circuit applications (NP0, P100, N33, N75, etc.). Class 2: offers high volumetric efficiency for buffer, bypass, and coupling applications (X7R, X5R, Y5V, Z5U, etc.). Class 1 ceramic capacitors offer the highest stability and lowest losses.
