Maximal available capacitance values of MLCC Chips in case size 2012. (Status April 2017) Capacitance of MLCC chips depends on the dielectric, the size and the required voltage (rated voltage). Capacitance values start at about 1pF. The maximum capacitance value is determined by the production technique. For X7R that is 47 μF, for Y5V: 100 μF.
Capacitance values up to 2,700,000 μF/6.3 V. Voltage up to 550 V. Lowest cost per capacitance/voltage values. Used where low losses and high capacitance stability are not of major importance, especially for lower frequencies, such as by-pass, coupling, smoothing and buffer applications in power supplies and DC-links. Polarized.
For capacitances following the (E3, E6, E12 or) E24 series of preferred values, the former ANSI/EIA-198-D:1991, ANSI/EIA-198-1-E:1998 and ANSI/EIA-198-1-F:2002 as well as the amendment IEC 60062:2016/AMD1:2019 to IEC 60062 define a special two-character marking code for capacitors for very small parts which leave no room to print any longer ...
Electrolytic capacitors offer very high capacitance but suffer from poor tolerances, high instability, gradual loss of capacitance especially when subjected to heat, and high leakage current. Poor quality capacitors may leak electrolyte, which is harmful to printed circuit boards. The conductivity of the electrolyte drops at low temperatures ...
The capacitance value measured at the frequency of 1 kHz is about 10% less than the 100/120 Hz value. Therefore, the capacitance values of polymer e-caps are not directly comparable and differ from those of film capacitors or ceramic capacitors, whose capacitance is measured at 1 kHz or higher.
105K 330V implies a capacitance of 10 × 10 5 pF = 1 μF (K = ±10%) with a working voltage of 330 V. 476M 100V implies a capacitance of 47 × 10 6 pF = 47 μF (M = ±20%) with a working voltage of 100 V. Capacitance, tolerance and date of manufacture can be indicated with a short code specified in IEC/EN 60062.
The capacitance value specified in the data sheets of the manufacturers is called the rated capacitance C R or nominal capacitance C N and is the value for which the capacitor has been designed. The standardized measuring condition for electrolytic capacitors is an AC measuring method with 0.5 V at a frequency of 100/120 Hz at a temperature of ...
The capacitance temperature dependence of polyester film capacitors is relatively high compared to other film capacitors, ±5% over the entire temperature range. The capacitance frequency dependence of polyester film capacitors compared with the other film capacitors is -3% in the range from 100 Hz to 100 kHz at the upper limit.
