10X 5.5V 1.5F Super Capacitor C-Type Button Capacitor High Energy Low Resistance High Consistency Set

Work well in various ways

I bought it to make a free-flight electric plane, and the capacity was higher than 1.5 F. I checked in the laboratory all 10 and the capacity was between 1.8F and 2.4F. Enough for a 30-second fly of my Depron model.

Most capacitors have a white stripe to indicate the cathode (negative). These ones are a fun surprise, not only lacking a part number, data sheet, or any other document for that matter, and have leads of equal length. Leads will connect to standard breadboard or dupont wires with female connectors.White stripe indicates the anode (positive) on these ones, may this information save someone from a small explosion.The capacity is excellent, I have one powering a 45mA load of LEDs for over 5 minutes after disconnecting power. These are probably amazing for keep-alives in model trains and other uses. Would be five stars if there was any documentation from manufacturer.

All tested at or above stamped capacitance value....quality capacitors, even accidentally reverse voltaged 3 of them in series @12VDC momentarily without any measurable damage taken...😬🫣🙏🙌👌👍
