After describing high reliability testing in our previous article, let’s discuss visual standards for chip capacitors. Multilayer ceramic capacitors (MLCCs) must possess fine workmanship and physical integrity, so visual inspection of the product is performed at 20X magnification to check for defects in the capacitor body and end metallization.
Parallel capacitors refer to a configuration where multiple capacitors are connected in parallel, meaning both terminals of each capacitor are connected to corresponding terminals of other capacitors. This arrangement effectively increases the total capacitance of the circuit. Key Characteristics of Parallel Capacitors:
C1, C2, C3, …, Cn are the individual capacitances of the capacitors. This formula indicates that the total capacitance of capacitors connected in parallel is simply the sum of the individual capacitances. To calculate the total capacitance of capacitors connected in parallel, you can use the following formula: Ceq = C1 + C2 + C3 + … + Cn Where:
However, given the capacitor construction some non-destructive tests are not applicable. Destructive testing usually requires a cross-section and inspection; in some cases de-encapsulation or de-lid is performed to inspect internal surfaces. For leaded devices, it is likely that terminal strength testing or lead pull testing is to be performed.
These two basic combinations, series and parallel, can also be used as part of more complex connections. Figure 8.3.1 8.3. 1 illustrates a series combination of three capacitors, arranged in a row within the circuit. As for any capacitor, the capacitance of the combination is related to both charge and voltage:
To add parallel capacitors, you simply sum the individual capacitances. This is because connecting capacitors in parallel increases the total plate area, effectively increasing the capacitance. Formula: Example:
