Are capacitors affected by temperature
For example, a failing capacitor can affect the DC output level of a DC power supply because it can''t effectively filter the pulsating rectified voltage as intended. This results in a lower average DC voltage and causes a corresponding erratic behavior due to unwanted ripple – as opposed to the expected clean DC voltage at the load.

Electrolytic Capacitor Failure and How it Affects Circuits
For example, a failing capacitor can affect the DC output level of a DC power supply because it can''t effectively filter the pulsating rectified voltage as intended. This results in a lower average DC voltage and causes a corresponding erratic behavior due to unwanted ripple – as opposed to the expected clean DC voltage at the load.
