Capacitor Electrolytic 100uF 16V - Pack of 10 47uf 2V LiIon or LiPoly batteryElectrolytic Capacitor 16V 100F Pack of 10 The Electrolytic Capacitor 16V 100F (Pack of 10) is a polarized aluminum electrolytic capacitor rated for 16V maximum and 100F capacitance. A common value for power filtering, decoupling, and audio coupling in electronic projects. Voltage rule: Always use a capacitor rated for at least 1. 5 to 2 your actual circuit voltage. This 16V cap is safe for circuits up to ~10V for reliable, long term operation. Common
