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.
Thin (down to 100 μm). Smaller footprint than most MLCC. Low ESL. Very high stability up to 200 °C. High reliability: Customized production Variable capacitors: Air gap tuning capacitors: Air: Circular or various logarithmic cuts of the rotor electrode for different capacitance curves. Split rotor or stator cut for symmetric adjustment.
The capacitance value specified in manufacturers data sheets is called the rated capacitance C R or nominal capacitance C N. It is given according to IEC 60063 in values corresponding to the E series. These values are specified with a capacitance tolerance in accordance with IEC 60062 preventing overlaps.
For example, in charging such a capacitor the differential increase in voltage with charge is governed by: = where the voltage dependence of capacitance, C(V), suggests that the capacitance is a function of the electric field strength, which in a large area parallel plate device is given by ε = V/d.
Since the SEPIC converter transfers all its energy via the series capacitor, a capacitor with high capacitance and current handling capability is required. The fourth-order nature of the converter also makes the SEPIC converter difficult to control, making it only suitable for very slow varying applications.

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 ...
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.).
