Electrolytic Capacitor 4.7 uF 50 V
⚡ Electrolytic Capacitor – 25V to 50V Rated Voltage
📝 Overview
Electrolytic capacitors are polarized capacitors known for their high capacitance-to-volume ratio, making them ideal for filtering, decoupling, timing, and energy storage in DC power supply circuits. These capacitors rated between 25V and 50V are widely used in low-to-mid voltage applications such as Arduino circuits, audio amplifiers, power regulators, and motor drivers.
