BESTCAPTM: A NEW GENERATION OF PULSE SUPERCAPACITORS Supercapacitors, (also referred to as Electrochemical Capacitors or Double Layer Capacitors) have rapidly become recognized, not only as an excellent compromise between "electronic" capacitors such as ceramic, tantalum, film and aluminium electrolytic, and batteries (Fig. 1), but also as a valuable technology for providing a unique combination of characteristics, particularly very high energy, power and capacitance densities. Fig. 1 Specific Energy of Capacitor Types 10000 SPECIFIC ENERGY Specific Energy (mFV/cc) 1000 100 UM AL NT TA R C I ME LY LYT PO TRO IUM C N I E EL LUM A 0.1 1 ELECTROLYTIC CAPACITOR 10 100 10 1000 1 10000 Capacitance (mF) There are two negative characteristics associated with conventional supercapacitors: high ESR in the Ohms or tens of Ohms area, and severe capacitance loss when called upon to supply very short duration current pulses. BestCapTM successfully addresses both of these drawbacks. This capacitance loss in the millisecond region is caused by the charge transfer (i.e. establishment of capacitance) being carried out by relatively slow moving ions in double layer capacitors. In the abovementioned "electronic" capacitors the charge transfer is performed by fast electrons, thereby creating virtually instant rated capacitance value. Fig. 2 illustrates the severe capacitance loss experienced by several varieties of supercapacitors under short pulse width conditions. It can also be seen from Fig. 2, how well BestCapTM retains its capacitance with reducing pulse widths. Actual Cap. (% of Nominal) Fig. 2 Actual capacitance vs. pulse width EDLC=Electrochemical double layer capacitor 100% 80% Aluminium Electroytic Capacitor 60% manufacturer A EDLC 40% manufacturer B EDLC manufacturer C EDLC 20% 0% 1000 10 100 1 Pulse Width (msec) 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 V(IR) total=I*R + I*t/C(t) V(Q)=I* t/C(t) Vt t The instant voltage drop V (IR) is caused by and is directly proportional to the capacitor's ESR. The continuing voltage drop with time V (Q), is a function of the available charge, i.e. capacitance. From figures 3 and 4, it is apparent that for very short current pulses e.g. in the millisecond region, the combination of voltage drops in a conventional supercapacitor caused by a) the high ESR and b) the lack of available capacitance, causes a total voltage drop unacceptable for most applications. Now compare the BestCapTM performance under such pulse conditions. The ultra-low ESR (milliOhm) minimizes the instantaneous voltage drop, while the high retained capacitance reduces the charge related drop. EFFICIENCY/TALKTIME BENEFITS OF BESTCAPTM Using a BestCapTM in parallel with a battery, provides a current pulse with a substantially higher voltage than that available from the battery alone (see Fig. 5). Thus the efficiency of the RF power amplifier is improved. 4 5 3.8 4 3.6 3 3.4 2 3.2 1 3 0 0 1000 2000 3000 Current (Amps) Battery Voltage (Volts) Fig. 5 GSM Pulse 4000 Time (uSeconds) Battery Voltage Battery and Capacitor Voltage Current Pulse Additionally, the higher-than battery voltage supplied by the BestCapTM keeps the voltage pulse above the "cut off voltage" limit for a significantly longer time than is the case for the battery alone.

Polarity BestCapTM capacitors are non-polar, and therefore can handle both positive and negative voltages. 8. Mounting BestCapTM may not be reflow or wave soldered. Hand soldering of the device is acceptable. When hand soldering, use a soldering iron of <30W rating and ensure that the tip temperature does not exceed +350C. Duration of the soldering operation should be <3 sec. Other non hand soldering technics such as by pulse soldering machine may apply. For further information please contact your local AVX representative. 9. Other Precautions * Do not disassemble the capacitor * Do not dispose of the capacitor by incineration. * Should the internal material come in contact with the skin or eyes, wash/rinse thoroughly with running water. 10.
