Suggestions on Handling Supercaps

Supercapacitors (Supercaps) combine the high energy density of batteries with the fast charge/discharge capability of capacitors. They are particularly suitable for applications that require fast energy bursts. The following are important notes and application recommendations for handling prismatic SCHURTER supercaps.

SCHURTER supercapacitors are “burned-in” during production and have a defined polarity, which is indicated by the positive terminal marked on the product. Reversing the polarity will not damage the product, but may lead to an increase in ESR and invalidate the warranty.

Dual-cell supercapacitor modules contain two cells connected in series. It must be ensured that the voltage of both cells remains below the maximum permissible operating values. SCHURTER recommends the use of an active balancing circuit or passive balancing resistors to avoid overvoltage of a single cell.

SCHURTER supercapacitors are supplied in a discharged state. They should only be handled and soldered in this state.
