The primary effects of ESR are cell design and materials. Most of the ESR in supercapacitors is determined by how the manufacturer makes connections from the active electrode to the terminals that the customer sees. The next biggest effect is materials – electrolyte and electrode materials and how the electrode is processed.

Trimmer capacitors are variable components used to calibrate RF circuits during manufacturing or servicing. These components allow for variable tuning–think oscillator frequency values or rise and fall times. Should values drift over the life of the device, trimmer capacitors can be recalibrated as needed.
