680 uF 16V Through Hole Electrolytic Capacitor (Pack of 20)

It seems like you’re describing a package containing 20 through-hole electrolytic capacitors, each with the following specifications:

• Capacitance: 680 microfarads (uF)
• Voltage Rating: 16 volts (V)
• Type: Through-hole type

The insulator that sits between the electrode’s relative conductors in each capacitor is likely the dielectric material. In electrolytic capacitors, this dielectric is typically a thin oxide layer formed on one of the electrodes during manufacturing. This dielectric layer separates the two electrodes, allowing the capacitor to store electrical charge.

These capacitors with a capacitance of 680 uF and a voltage rating of 16V are suitable for various electronic applications, particularly where relatively high capacitance values and moderate voltage ratings are required. They can be used in power supply circuits, filtering applications, decoupling, and smoothing voltage ripple in DC power supplies, among other uses. The through-hole design allows for easy mounting on a circuit board by inserting the leads through holes in the board and soldering them in place.
