Panasonic FM Low ESR Electrolytic Capacitors

  • Sale
  • Regular price $1.05


This is the industry standard capacitor for multirotors. They are some of the lowest ESR options on the market for the given size. You need these to help manage electrical noise.

If you have random jitters, ticks or a shaky/fluttering quad, you may have electrical noise in the system and you can try applying a capacitor to see if it will help.

To use any capacitor correctly, solder no smaller than 18awg wires as close to the base of the capacitor as possible and connect them to the batt in pads on the ESC/AIO board with no more than 1” or 25mm length of the 18awg wire. Thicker wire doesn’t help much to give you a longer distance from the battery in pads. Ideally less than 20mm is preferred.

The correct size depends on your drivetrain and voltage. Generally, 25v is used for 2S-4S and 35v is used for 6S. No quad in the 2”-6” range should need more than 1000uf of capacitance. If it does need more, your ESC is not a good match for the motor/prop combo. The lower power the quad is, the less capacitance you can get away with.
