Cap/Diode System For Motor Noise Suppression

  • Sale
  • Regular price $8.99


Use this for any 6S multirotor application with motors up to 2806.5. Use one Cap/Diode system per four motors and solder directly to batt pads on ESC or AIO. This product is designed with the appropriate wire length, thickness and quality to be maximally effective in the smallest and lightest package for the job. We do not recommend longer or different gauge wires. Shorter wire length is best.

What actually is this product?

If you're operating a modern multirotor, you're probably using modern ESC's which often struggle to manage electronic noise coming from the motors. This electronic noise can cause significant performance fluctuations in your flight controller or completely fry components on your craft. This product is designed to help manage electronic noise to improve both performance and longevity of components. It has been specifically designed to be very easy to use and as effective as possible in a very light and small package given it's performance.

This capacitor is paired with TVS diodes on a board such that they complement each other. It's a 35V 820uf FR series Panasonic capacitor with TVS diodes that will shunt 18A at 28V. The two operate very differently. While the diodes function extremely quickly and with extremely low latency, the capacitor will better manage sustained electrical fluctuations also with extremely low latency.

This product is directly targeted at 5" 6S FPV quads but works very well elsewhere too.

Sick

Awesome. So small but effective.

Works as expected

It works as expected....its the same as a fettec spike absorber but comes with the cap and is ready to go

Quality

Quality made product that's a Perfect match / size for my 3" and 4" builds. Until now adding a tvs diode to smaller quads was not practical or even possible. Get the added protection with this combo.
