AI Customer ServiceThe range of units used to specify capacitor values has expanded to include everything from pico- (pF), nano- (nF) and microfarad (μF) to farad (F). Millifarad and kilofarad are uncommon. The percentage of allowed deviation from the rated value is called tolerance.
According to the number of values per decade, these were called the E3, E6, E12, E24 etc. series. The range of units used to specify capacitor values has expanded to include everything from pico- (pF), nano- (nF) and microfarad (μF) to farad (F). Millifarad and kilofarad are uncommon.
The temperature coefficient for the capacitance of compressed gas capacitors according to Fig. 11.10 is typically in the range of (2–3) × 10 −5 K −1. For accurate capacitance measurements, it is recommended to use a low-voltage bridge that is more accurate and easier to use than a high-voltage bridge.
The dielectric, made of tantalum pentoxide, has a minimum thickness of 1.4 nm/V. Indeed, this type of capacitor generally has a larger capacitance value since it has a very thin dielectric layer with higher permittivity than aluminum capacitor (see Table 2).
The nominal value of the Capacitance, C of a capacitor is the most important of all capacitor characteristics. This value measured in pico-Farads (pF), nano-Farads (nF) or micro-Farads (μF) and is marked onto the body of the capacitor as numbers, letters or coloured bands.
Capacitors are rated according to how near to their actual values they are compared to the rated nominal capacitance with coloured bands or letters used to indicated their actual tolerance. The most common tolerance variation for capacitors is 5% or 10% but some plastic capacitors are rated as low as ±1%.
