Why Capacitance Changes & Capacitance Variation In our circuit applications, the capacitor can be and is subjected to various electrical, mechanical, and environmental stresses. One of the most noticeable effects of these stresses is the phenomena of capacitance variation.
In our circuit applications, the capacitor can be and is subjected to various electrical, mechanical, and environmental stresses. One of the most noticeable effects of these stresses is the phenomena of capacitance variation. Now, the fact that the capacitance does vary will come as no surprise to most design engineers.
A (effective area of electrodes) is set by design and once a capacitor is made, it is almost impossible for C to change due to a change in A. This, then, is not a normal factor in capacitance variation. d (distance between the plates) is also set by design.
The area of the surface building up the capacitor can affect the capacitance of that capacitor in a direct proportion i.e., a higher surface area capacitor produces a higher capacitance capacitor. If C is the capacitance and A is the surface area of one side of the capacitor, then.
Changes in temperature around the capacitor affect the value of the capacitance because of changes in the dielectric properties. If the air or surrounding temperature becomes to hot or to cold the capacitance value of the capacitor may change so much as to affect the correct operation of the circuit.
tors: capacitors for temperature compensation and high dielectric constant capacitors. Capacitors for temperature ompensation (C0G, NP0 type etc.) show little change in capacitance due to temperature. On the other hand, the high dielectric constant type (X5R, X7R etc.) demonstrates a typical change in temperature.
