PCB technology Electrolytic capacitors and capacitors

one. Fixed capacitor: refers to a capacitor whose capacitance cannot be changed once it is made. Capacitors can generally be divided into non-polar ordinary capacitors and polar electrolytic capacitors. Common capacitors are divided into fixed capacitors, semi-adjustable capacitors (trimming capacitors), and variable capacitors. 1. Classification of capacitors: Capacitors are generally classified by dielectric. 1) Paper-membrane…
