Content: In circuit design, the selection of capacitors directly affects product stability. This article summarizes three key points: 1. The capacitance value needs to be matched according to the signal frequency and filtering requirements; 2. A safety margin of more than 20% must be reserved for the voltage resistance value; 3. Select the appropriate material according to the working temperature. ChipRoute professional team can provide one-on-one selection consultation to help you design efficiently.
