Capacitor Discharge Time Calculator (with Examples)

The discharge time of a capacitor is primarily governed by the RC time constant (often denoted as τ), where R is the resistance through which the capacitor discharges, and C is the capacitance. The time constant represents the time required for the voltage across the capacitor to decrease to about 36.8% (substitute t=RC in the equation e −t/RC .

Capacitor discharge...

As the capacitor discharges, the voltage falls. The charge Q = C x V, so the voltage V = Q/C falls as the charge flows out of the capacitor. This is true for any value of the discharge-circuit resistance: lower resistance makes the discharge current higher and therefore the time required to remove the charge faster.

6 FAQs about [Canberra Super Discharge Capacitor]

Can a super capacitor be discharged down 0 V?

All trademarks are the property of their respective owners. Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current.

How do you charge a super capacitor?

Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current. A simple voltage regulating LED driver with constant current, usually regulated by sensing a low side, series current sense resistor, then a voltage clamp can be used to charge a super capacitor.

What are supercapacitors & EDLC?

Supercapacitors, also known as ultracapacitors and electric double layer capacitors (EDLC), are capacitors with capacitance values greater than any other capacitor type available today. Supercapacitors are breakthrough energy storage and delivery devices that offer millions of times more capacitance than traditional capacitors.
