Where should capacitors be placed in a PCB?

The placement of capacitors is one of the most critical phases of the PCB design process. Incorrect capacitor placement can completely revoke their performance. Place capacitors on the bottom side of the board with respect to SMT component placement.

How should a capacitor be placed in a decoupling circuit?

The first and most important rule for decoupling capacitor placement is to place them as close as possible to the power pins of the IC. This minimizes the inductance in the power supply path, which is critical for high-frequency decoupling. The closer the capacitor is to the power pin, the lower the inductance, and the better the decoupling.

Where should a capacitor be placed?

This means the caps should be placed on the pin for ICs and near the connector for I/O signals. To remove low-frequency transients from input and output signals, the capacitor should be connected in series with the trace. High-frequency will pass through the capacitor, but low-frequency and DC will be blocked.

Where should a PCB decoupling capacitor be placed?

You may be able to implement a better arrangement if you can place your bypass capacitor on the bottom side of the board. After you determine the size of the PCB decoupling capacitor you need in your PDN, you’ll need to place it somewhere to ensure it can compensate for input voltage fluctuations.

Where should a bypass capacitor be placed on a PCB?

Refer to the schematic to ensure the placement of bypass capacitors at the device power pins and not at high logic pins. Capacitors are the most versatile components from the PCB assembly standpoint, and decoupling is one of their chief functions.

Why is it important to know the operating range of a capacitor?

Understanding the operating range of frequencies is critical for decoupling capacitor placement to avoid EMI and EMC issues.
