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.

BestCap™ successfully addresses both of these drawbacks.

BESTCAP™: 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.

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. 2 Actual capacitance vs. pulse width

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 above-

mentioned "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 BestCap™ retains

its capacitance with reducing pulse widths.

Fig 4 Voltage-time relation of capacitor unit

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 BestCap™ 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.

Additionally, the higher-than battery voltage supplied by the BestCap™ keeps the voltage pulse above the "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) and 6b) (Li-Ion at 0°C).

EFFICIENCY/TALKTIME BENEFITS OF BESTCAP™

Using a BestCap™ 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.

7. Polarity

BestCap™ capacitors are non-polar, and therefore can handle both positive and negative voltages.

8. Mounting

BestCap™ 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 +350°C. 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.
