Yokomo Nonpolar Receiver CapacitorYokomo (#BL RRCP) Nonpolar Receiver Capacitor Feature: This capacitor is connected to the BEC channel of the receiver to reduce noise and stabilize the servo current. When a large load is placed on the servo during driving, the capacitor can momentarily supplement power to stabilize the servo's operation. Since it is non polarized, it can be easily installed by simply connecting it to the positive and negative connectors on the receiver.
