... Ultra-low ESR High Power Pulse Supercapacitors GENERAL DESCRIPTION ™ The BestCap series of electrochemical supercapacitors offer excellent high power pulse characteristics based upon the combination of very high capacitance and ultra low ESR in the milliOhm region. Based on a unique patented aqueous chemistry and an innovative design, the system offers high capacitance, even with short pulse duration regimes such as in GSM and PCS based systems, together with a variety of voltage ratings ...

... Fig. 1 Specific Energy of Capacitor Types SPECIFIC ENERGY 0.1 There are however, two negative characteristics associated with conventional supercapacitors, viz: high ESR in the Ohms or tens of Ohms area, and severe capacitance loss when called upon to supply very short duration ™ current pulses. BestCap successfully addresses both of these drawbacks ...

... Fig. 2 illustrates the severe capacitance loss experienced by several varieties of supercapacitors (N, M & P), under short pulse width conditions. It can also be seen from Fig. 2, ™ how well BestCap retains its capacitance with reducing pulse widths ...

VOLTAGE DROP Two factors are critical in determining voltage drop when a capacitor delivers a short current pulse; these are ESR and “available” capacitance as shown in Fig. 4. Fig 4 Voltage-time relation of capacitor unit Vo Vt The instant ...

Additionally, the higher-than battery voltage supplied by the BestCap “cut off voltage” limit for a significantly longer time than is the case for the battery alone. This increase in “talktime” is demonstrated in figures 6a) (Li-Ion at +25°C); 6b) (Li-Ion ...

... BESTCAP ™ INRUSH CURRENT/SHORT CIRCUIT DISCHARGE CAPABILITIES Testing of capacitors, including supercapacitors, is normally carried out using milliAmpere signals. However, for many applications it is important to know the true capability of the device in terms of inrush and discharge currents. In Figs. 7 & 8, shown below, show BestCap discharging with a peak current of 25 Amps (48 x 30mm version) into a load impedance of approximately 70 milliOhms ...

... Polarity BestCap ™ capacitors are non-polar, so can handle both positive and negative voltages. The polarity marking on ESR –6 = 40µA (40*10 Amp.) the label relates to internal test procedures only and may be ignored in normal use. 5. Mounting ™ ...
