Take into account the capacitance, voltage rating, ripple current rating, and temperature when selecting a capacitor. The physical size of a capacitor depends on the capacitance value. As the capacitance increases, the size becomes larger. The capacitance variation is temperature-dependent.
Here’s a guide on how to find capacitor size: Understand Circuit Needs: Begin by understanding the specifications of your circuit, including voltage, current, frequency, and any specific performance requirements. Calculate Capacitance: Use the formula (C = \frac {Q} {V}) to calculate the required capacitance.
Usually, capacitors are derated by the following rule of thumb: a capacitor is selected such that its voltage rating is two to three times greater than the expected operating voltage. Derating increases the footprint requirements of the capacitor because, with an increase in working voltage, the physical size of the capacitor also increases.
It will also depend on the physical size requirement. The capacitor physical size is directly proportional to the voltage rating in most cases. For instance, in the sample circuit above, the maximum level of the voltage across the capacitor is the peak level of the 120Vrms that is around 170V (1.41 X 120V).
Capacitors with the same capacitance but different tolerance levels are available. The physical size of the capacitor is dependent on the capacitance value; as the capacitance increases, the size becomes larger. The voltage rating is the maximum continuous DC or AC voltage that a capacitor can withstand without failing.
Let’s explore the key factors that influence capacitor sizing decisions. The voltage rating of a capacitor determines the maximum voltage it can withstand without experiencing failure. When sizing a capacitor, always choose one with a voltage rating higher than the maximum voltage in your circuit to prevent breakdown and damage.
