The different ceramic materials used for ceramic capacitors, paraelectric or ferroelectric ceramics, influences the electrical characteristics of the capacitors. Using mixtures of paraelectric substances based on titanium dioxide results in very stable and linear behavior of the capacitance value within a specified temperature range and low losses at high frequencies.
The rated capacitance C R or nominal capacitance C N is the value for which the capacitor has been designed. Actual capacitance depends on the measured frequency and ambient temperature. Actual capacitance depends on the measured frequency and ambient temperature.
For brevity, the notation omits to always specify the unit (ohm or farad) explicitly and instead relies on implicit knowledge raised from the usage of specific letters either only for resistors or for capacitors, [nb 1] the case used (uppercase letters are typically used for resistors, lowercase letters for capacitors), [nb 2] a part's appearance, and the context.

EMI or ESD suppression typically is realized with RC or R(C)-diode networks. limitations of performance (like Q factors of the coils) and values (like large capacitance values) of passive elements available in integrated circuit technologies like CMOS as monolithically integrated with active elements (transistors etc.).
Low-temperature co-firing technology presents advantages compared to other packaging technologies including high-temperature co-firing: the ceramic is generally fired below 1,000 °C due to a special composition of the material. This permits the co-firing with highly conductive materials (silver, copper, and gold).
is the lossless capacitance. A real capacitor has a lumped element model of a lossless ideal capacitor in series with an equivalent series resistance (ESR). The loss tangent is defined by the angle between the capacitor's impedance vector and the negative reactive axis.
The capacitance value specified in manufacturers' data sheets is called the rated capacitance C R or nominal capacitance C N and is the value for which the capacitor has been designed. Standardized measuring conditions for electrolytic capacitors are an AC measurement with 0.5 V [ clarification needed ] at a frequency of 100/120 Hz and a ...
