General Description  
Effects of Mechanical Stress – High “K” dielectric  
ceramic capacitors exhibit some low level piezoelectric  
reactions under mechanical stress. As a general statement,  
the piezoelectric output is higher, the higher the dielectric  
constant of the ceramic. It is desirable to investigate this  
effect before using high “K” dielectrics as coupling capaci-  
tors in extremely low level applications.  
Energy Stored – The energy which can be stored in a  
capacitor is given by the formula:  
E = 1⁄ CV2  
2
E = energy in joules (watts-sec)  
V = applied voltage  
C = capacitance in farads  
Reliability – Historically ceramic capacitors have been one  
of the most reliable types of capacitors in use today.  
The approximate formula for the reliability of a ceramic  
capacitor is:  
Potential Change – A capacitor is a reactive component  
which reacts against a change in potential across it. This is  
shown by the equation for the linear charge of a capacitor:  
Lo  
Lt  
Vt  
X
Tt  
Y

Iideal

where  
Lo = operating life  
Lt = test life  
Vt = test voltage  
Tt = test temperature and  
To = operating temperature  
in °C  
where  
I = Current  
C = Capacitance  
Vo = operating voltage  
X,Y = see text  
dV/dt = Slope of voltage transition across capacitor  
Thus an infinite current would be required to instantly  
change the potential across a capacitor. The amount of  
current a capacitor can “sink” is determined by the above  
equation.  
Historically for ceramic capacitors exponent X has been  
considered as 3. The exponent Y for temperature effects  
typically tends to run about 8.  
Equivalent Circuit – A capacitor, as a practical device,  
exhibits not only capacitance but also resistance and  
inductance. A simplified schematic for the equivalent circuit  
is:  
A capacitor is a component which is capable of storing  
electrical energy. It consists of two conductive plates (elec-  
trodes) separated by insulating material which is called the  
dielectric. A typical formula for determining capacitance is:  
C = Capacitance  
L = Inductance  
Rs = Series Resistance  
Rp = Parallel Resistance  
.224 KA  
C =  
t
RP  
C = capacitance (picofarads)  
K = dielectric constant (Vacuum = 1)  
A = area in square inches  
t = separation between the plates in inches  
(thickness of dielectric)  
L
R S  
.224 = conversion constant  
C
(.0884 for metric system in cm)  
Reactance – Since the insulation resistance (Rp) is normal-  
Capacitance – The standard unit of capacitance is the  
farad. A capacitor has a capacitance of 1 farad when 1  
coulomb charges it to 1 volt. One farad is a very large unit  
ly very high, the total impedance of a capacitor is:  
2
2
Z = RS + (XC - XL)  
-6  
and most capacitors have values in the micro (10 ), nano  
ꢀ
where  
-9  
-12  
(10 ) or pico (10 ) farad level.  
Z = Total Impedance  
Dielectric Constant – In the formula for capacitance given  
above the dielectric constant of a vacuum is arbitrarily cho-  
sen as the number 1. Dielectric constants of other materials  
are then compared to the dielectric constant of a vacuum.  
Rs = Series Resistance  
XC = Capacitive Reactance =  
1
2 π fC  
XL = Inductive Reactance = 2 π fL  
Dielectric Thickness – Capacitance is indirectly propor-  
tional to the separation between electrodes. Lower voltage  
requirements mean thinner dielectrics and greater capaci-  
tance per volume.  
The variation of a capacitor’s impedance with frequency  
determines its effectiveness in many applications.  
Phase Angle – Power Factor and Dissipation Factor are  
often confused since they are both measures of the loss in  
a capacitor under AC application and are often almost  
identical in value. In a “perfect” capacitor the current in the  
capacitor will lead the voltage by 90°.  
Area – Capacitance is directly proportional to the area of  
the electrodes. Since the other variables in the equation are  
usually set by the performance desired, area is the easiest  
parameter to modify to obtain a specific capacitance within  
a material group.
