TOVOT 14 PCS Farad Capacitors 0.1 to 4 F Super Capacitor V Type Assortment Kit Set (5.5V)

Very nice! The super capacitors came in a nice little plastic box and I tried them out by lighting up two standard red LED in series and they stayed lit for a long time, especially with the 4F capacitor!I still don't know what the ESR of them are, but when I hooked up 4F cap to the 5V, 5 Amp power supply, the peak current on the digital display was about 800 to 1,000 mA which, if it really is the peak, would suggest and ESR of about 6 Ohms. But I really need to look at the current peak with a scope on a really slow timebase to know for sure.

The Supercaps were great! However, the C-shape 4.0F capacitor had overly thick leads, so I solved the problem by "squishing" the leads (as shown in the picture)

Great set. Used ias a memory battery replacement in an older chess computer, where the older original battery was prone to leakage/corrosion. Although the original battery showed no signs of corrosion, it was over 20 years old. Works great and no more worries about a battery corroding!

I haven't been able to test these yet.Pro:Handy case and nice assortment of values for both Horizontal and Vertical mounting.Arrived on time.Con:14 PCS total but missing 1.0F 5.5V H, instead there were two 1.5F 5.5V H.No datasheet or discernible product markings. It would be helpful to know what is the ESR of these types of capacitors.

The super caps are all perfect looking, no bent prongs or scratches. They are a little heavy for the size they are and very strong. Great investment for diy inventions. Wish they would post some technical specs though.

great combo of supercaps for experimenting

The package came in fine condition, it was not opened. However it was missing the 1.0F Super Capacitors, both the H and V Type.
