Application fields: Battery-powered DC brushless motor controllers, connected in parallel to the positive and negative terminals of lithium batteries, are used to absorb high-frequency ripple and noise generated by DC motors, and to absorb the self-induced pulse spike voltage of motor coils. For power supplies with very low internal resistance such as lithium batteries, there is a large charging current (more than 100 amps) at the moment of power-on, and ordinary electrolytic capacitors are usually damaged because of this.

The new FC series can withstand large inrush current and meet the requirements for frequent startup.

Measures: 1. The rolling machine needs a pre-punching device to reduce the riveting surface aluminum shavings and burrs during riveting and reduce the chance of ignition. 2. For aluminum electrolytic capacitors, the ability to withstand reverse voltage mainly depends on the thickness of the oxide film of the cathode foil, pressurize 2VF on cathode foil through the cathode foil, and the pad foil design is used to increase the ability to withstand large ripple current. 3. Using paper pad (SM255-50) design, the existing machine also has paper pad function, but the position is on the cathode terminal rivet surface, which cannot play the function of resisting DC high current impact. This item adjusts the pad position at the anode terminal rivet.
