Capacitors for Spacecraft: Withstanding a Harsh Radiation

During radiation capacitor leakage resistance decreases and, as a result, the time constant of the circuit will also decrease. If the capacitor is in a critical timing circuit, the timing circuit may produce errors that affect system performance.

8.2: Capacitors and Capacitance

The main advantage of an electrolytic capacitor is its high capacitance relative to other common types of capacitors. For example, capacitance of one type of aluminum electrolytic capacitor can be as high as 1.0 F. However, you must be careful when using an electrolytic capacitor in a circuit, because it only functions correctly when the metal foil is at a
