Capacitor Values: Standard capacitor values align with the E-series, including E12 and E24, with options like 0.1µF, 0.22µF, 0.47µF, and 1µF. Voltage ratings range from 6.3V to 100V or higher, ensuring safety in various circuits. Tolerances span from ±20% for general-use electrolytic types to ±1% for precision ceramics.
Voltage Rating: The voltage rating defines the maximum voltage a capacitor can handle safely. Exceeding this rating risks breakdown and failure. Higher voltage-rated capacitors are often bulkier and may restrict available capacitance values. Choosing the right voltage rating ensures both safety and efficiency in your circuits.
If the capacitor is ideal the current would rapidly attain the limiting value corresponding to the IR. The ideal current curve is designated I C-ideal. But because the polarization in the dielectric requires a finite time for dipoles to reorient the real charging current follows the curve I C-polarization. Figure 2.
As a general rule, a properly designed capacitor of sound construction should withstand the normal 25°C dielectric withstanding flash voltage even when the temperature is 125 ° C.
