The RUSH BLADE Power Filter Board by RUSHFPV was created to help the RUSH BLADES ESCs achieve complete filtering due to their compact structure and high power. Excessive voltage peaks can cause interference to other components. Current surges generated during crashes can also have a strong impact on the MOSFETs and the power supply, potentially causing damage.
The RUSH PFB is small in size and can be installed at the tail of the ESC as a supplementary device for the filter. It is equipped with two 35V 330uF high-speed solid capacitors, and the parallel ESR is very low, only 5 m0 (TEST FREQ @10KHz)! It has a good filtering effect on high-frequency interference generated by the ESC.
There are 3 high-power TVS diodes on board, which can cut voltage peaks at ns speeds and absorb high-voltage surges caused by collisions of the propeller during a crash in time to protect the field-effect tube and other components from the surge. We recommend installing it in a high-power 6S brushless system.
