The impedance of capacitors and inductors in a circuit depend on the frequency of the electric signal. 50V 1210 ceramic capacitor with the following impedance vs. Capacitors do like to pass current at low frequencies As the frequency becomes very large ω→∞ the quantity Xc goes to zero which implies that the capacitor resembles a short circuit. For low-inductance capacitors, this mutual inductance is always significant, making published values for the ESL practically meaningless. The simple R-C filter rolls off the frequency response at 6 dB per octave above the cutoff frequency. Practical capacitors and inductors as used in electric circuits are not ideal components with only capacitance or inductance. Also look at the equivalent circuit diagram of a capacitor at the top of this page, There also seems to be a fraction more emphasis on the frequency extremes Impedance of capacitors depends on capacitance and frequency. A capacitor is really a capacitor in series with the resistances of its leads, the foil in the dielectric, and other small resistances. At very low frequencies, such as 1Hz our 220nF capacitor has a high capacitive reactance value of approx 723. The series inductance of the capacitor also raises the impedance, limiting its ability to pass AC current. RoHS compliant: It means the capacitor complies with the EU Directive 2002/95/EC requirement If there’s enough room on the capacitor, most manufacturers of electronics components print the capacitance directly on the capacitor along with other information such as the working voltage and perhaps the tolerance.
