capactiteitsvoltage

Capactiteitsvoltage is a term occasionally encountered in Dutch-language electronics literature and can refer to two related ideas concerning capacitors. In one sense it denotes the voltage across a capacitor during operation, i.e., the applied potential difference that determines how much charge the capacitor stores. In another sense it is used to describe the voltage dependence of a capacitor’s capacitance, the phenomenon that the stored capacitance can change when a DC bias is applied.

Voltage across a capacitor is characterized by its ratings and operating conditions. The maximum continuous voltage that a component can withstand without breakdown is commonly called the working voltage or voltage rating. Exceeding this value risks dielectric breakdown and device failure. For designers, knowing the capactiteitsvoltage is essential to ensure reliability and to avoid excessive leakage or distortion in signal paths.

Voltage-dependent capacitance, sometimes referred to as a voltage coefficient of capacitance, describes how C(v) changes with applied voltage. This nonlinearity is especially pronounced in certain dielectrics and device structures, such as ferroelectric capacitors, MOS capacitors, and varactors. It is typically quantified by dC/dV or by modeling C as a function of V, for example C(V) = C0 [1 + αV + …]. This behavior is exploited in tunable circuits, such as varactor-tuned filters, but it can also complicate precision timing and calibration.

Terminology varies: more common Dutch terms for the related concepts are werkspanning (voltage rating) and spanningsafhankelijke capaciteit (voltage-dependent capacitance). Capactiteitsvoltage thus serves as a shorthand for either the operating voltage or the voltage-related behavior of a capacitor, depending on context.
