Kt Tell You Pay Attention to 5 Variable Factors in Choosing Capacitors

When choosing your next capacitor. There are five variables to consider, including:
1. Size –
This includes both the physical size of your capacitor as well as its total capacitance. Don’t be surprised if your chosen capacitor is the largest part of your circuit board, as the more capacitance you need, the larger they get.
2. Tolerance –
Just like their resistor counterparts, capacitors also have a variable tolerance. You’ll find tolerance for capacitor anywhere between±1%to±20% of its advertised value. 3. Maximum Voltage –
Every capacitor has a maximum voltage that it can be handle. Otherwise, it will explode! You’ll find max voltages anywhere from 1.5V to 100V.
4. Equivalent Series Resistance (ESR) –
Like any other physical material, the terminals on a capacitor have a very tiny amount of resistance. This can become a problem if you need to be mindful of heat and power loss.
5. Leakage Current –
Unlike our batteries, capacitors will leak their stored charge. And while this drains slowly, you’ll want to pay attention to how much your capacitor leaks, if it’s primary function, is storing energy.
