Capacitor applications. Table credit: Wikipedia. Specifications Fixed vs. Variable. Capacitors can feature either fixed or variable capacitance. Fixed capacitors simply have a fixed, nonadjustable capacitance value.. Variable capacitors can be adjusted by the user, using either mechanical or electronic means. These are also known as tuning capacitors due to their common applications in radio.
