What is the difference between a resistor and a capacitor?

There are fewer standard values for capacitors compared to resistors. Generally, capacitors come available only in the E-6 Series of standard values (10, 15, 22, 33, 47, and 68) followed by a specified number of zeros. It may not be possible to have the exact value of desired capacitance in standard E-series.

What are the tolerances for resistors & capacitors?

Tolerances for resistors are optimum if you’re using 1%, 5%, and 10%. Tolerances for capacitors work best in 5% and 10% only. Power rating is important to determine because, through this, we can execute damage control and seamless power dissipation with it to a large extent.

How to choose a capacitor?

Therefore, the capacitance tolerances should be kept in mind while selecting the capacitor component for the application. The price variation between low tolerance and high tolerance capacitors varies considerably. If price is not a major concern, it is recommended to select a capacitor with tolerance under 10%.

Why are resistors and capacitors important in a PCB?
