Some capacitors use "MFD" which stands for "microfarads". While a capacitor color code exists, rather like the resistor color code, it has generally fallen out of favor.

This combination of pads, PCB tracks, pins, and components form a capacitor. How do PCB Capacitors Work? Capacitors found on printed circuit boards or PCBs often serve two primary purposes. They are capable of storing electric charge and allowing alternating current to flow through them while preventing direct current from doing so.
As a direct current flows into a capacitor, it charges with energy and releases an alternating current flow back into the circuit. Most capacitors have a positive and negative terminal in the form of legs, pads, or plates. Current flows into one of these legs, through the capacitor''s body, and out of the other leg.

However, if a voltage larger than the insulator will withstand (the working voltage) is applied, then the electrons will have enough energy to break through the insulator and cause a current to pass.
