With increasing voltage and decreasing panel thicknesses demands, traditional components are no longer sufficient. Backlights are generally modulated in the audible frequency range, which can result in noise from X5R and X7R ceramic capacitors. In circuits where piezoelectric noise isn’t acceptable, polymer capacitors offer quiet operation and long life in very slim packages. When 35 – 50 V rated components are needed with low profiles, polymer capacitors can be utilized in place of traditional V-chip aluminum surface mount capacitors.
