Practical Capacitor Tolerance Selection for Coupling, DC Blocking and Bypass Applications
Abstract:
Proper selection of suitable capacitor tolerances is governed to a great extent by the type of application under consideration. This point should always be taken into account when designing for the best balance between cost and performance. For example, DC blocking, coupling and bypassing applications are not very sensitive to the variations in capacitor value that are due to the choice of wide spread tolerances. In contrast, applications such as filtering and matching will usually require narrow spread capacitance tolerances in order to meet the specific demands of those designs.
