Revision 4.5, Feb 2024 **GY SERIES DATASHEET** 

## **Measurement of capacitance** 

Capacitance is measured at 25C using the method specified by IEC62391 shown in Fig 1. This measures DC capacitance. The capacitor is charged to rated voltage, VR, at constant current, held at rated voltage for at least 30 minutes and then discharged at constant current. The time taken to discharge from 0.8 x VR to 0.4 x VR is measured to calculate capacitance as: 

C = I x (T1 – T2)/(V1 – V2) 

**Fig 1: GY12R708012V105R Capacitance measurement** 

In this case, C = 1A x (1.416-0.3)s /(2.16 – 1.08)V = 1.03F, which is well within the 1F +30% / - 10% tolerance for a GY12R708012V105R cell.

Revision 4.5, Feb 2024 **GY SERIES DATASHEET** 

## **Measurement of DC ESR** 

Equivalent Series Resistance (ESR) is measured at 25C by applying a step load current to the supercapacitor and measuring the resulting voltage drop. CAP-XX waits for a delay of 200µs after the step current is applied to ensure the voltage and current have settled. In this case, for a GY12R708012V105R the ESR is measured as 140mV/1A = 140mΩ which is well below the specified maximum of 250mΩ.

Revision 4.5, Feb 2024 **GY SERIES DATASHEET** 

## **Measurement of Leakage Current** 

Leakage current is measured by holding the supercapacitor at rated voltage at 25C and charging it through a low value current limit resistor, in this case, 28. After the current through the 28 resistor has decayed the supercapacitor is then held on charge with a higher value sense resistor, typically 1KΩ or 2.2KΩ, and the voltage is measured across this resistor to determine leakage current. The leakage current decays over time as shown in Fig 3 which shows the average leakage current for 4 samples each of 1F, 2F, 5F and 10F supercapacitors. The datasheet quotes the maximum values after 72hrs. Leakage current decays to its final equilibrium value after ~120hrs, typically ~1µA/F as shown in Fig 3.

## **Variation in DC Capacitance and ESR with temperature** 

Figure 4 shows that DC capacitance does not vary significantly over the operating temperature range of -40C to +70C. 

**Fig 4: Typical variation in Capacitance over the operating temperature range** 

Figure 5 shows variation in DC ESR over the operating temperature range. 

**Fig 5: Typical variation in DC ESR over the operating temperature range** 

From Figure 5, ESRDC at -40C varies from ~2.6x to 1.1x ESRDC at room temperature depending on the part. ESRDC at 70C is ~90% of ESRDC at room temperature. The variation in ESR with temperature is due to the change in the mobility of ions in solution in the electrolyte and the characteristics of the activated carbon used in that part.

Revision 4.5, Feb 2024 **GY SERIES DATASHEET** 

## **Peak Current** 

Peak current is limited by Vrated/(ESR + RL) where RL is the load resistance including parasitic resistance such as PCB traces. The current then decays and is given by: 

[Vrated/(ESR + RL)].e[-t/[(ESR+RL).C]] 

where t = time in seconds. At high peak current, the supercapacitor discharges rapidly so that self heating due to the high current is negligible. Table 1 Shows short circuit current for a range of supercapacitors initially charged to 2.7V at the instant the short circuit is applied and after 100ms. It also shows the temperature increase recorded due to the short circuit. 

**Table 1:** 

|**Table 1:**||||
|---|---|---|---|
|Capacitance<br>(F)|Instantaneous<br>peak current<br>(A)|Current after<br>100ms (A)|Temperature<br>rise (C)|
|10|78|40|3.7|
|5|51|30|2.6|
|2|35|14|1.6|
|1|28|9|1|



In all cases the temperature rise is not significant. A one-time peak current pulse is only limited by the ESRDC + Load resistance, not by any thermal limitations. 

The voltage drop when a constant current pulse of duration  is applied = 

VINIT – VFINAL= I.ESRDC + I./C 

Where: 

I = constant current 

 = duration of constant current 

VINIT = the initial voltage when the current pulse is first applied 

VFINAL = the supercap voltage at the end of the pulse 

Re-arranging terms, the maximum current that can be sustained for a time , when the supercapacitor is initially charged to rated voltage, VR, and discharged to VMIN, the minimum voltage that supports the given application = 

**==> picture [90 x 28] intentionally omitted <==**

Note that if the duration of the constant current, , is short then you will need to use Ceff() accurately determine the voltage drop, or the max current for a given voltage drop over time . Please see the section on Effective Capacitance in this datasheet.

Revision 4.5, Feb 2024 **GY SERIES DATASHEET** 

## **Maximum Continuous Current** 

Continuous current flow into/out of the supercapacitor will cause self-heating, which limits the maximum continuous current the supercapacitor can handle. This is measured by a current square wave with 50% duty cycle, charging the supercapacitor to rated voltage at a constant current, and then discharging the supercapacitor to half rated voltage at the same constant current value. For a square wave with 50% duty cycle, the RMS current is the same as the current amplitude. Fig 6 shows the increase in temperature as a function of RMS current for various GY12R7 series supercapacitors. 

**Fig 6: Self heating with RMS current for various supercapacitors** 

From Fig 6, the maximum RMS current in an application can be calculated. For example, if the ambient temperature is 40C, and the maximum operating temperature for the supercapacitor is 70C, then the maximum RMS current for a 10F supercapacitor should be limited to 4.2A, which causes a 30C temperature increase.

Revision 4.5, Feb 2024 **GY SERIES DATASHEET** 

## **Effective capacitance (Ceff)** 

Effective capacitance is the capacitance seen for short pulse widths. Due to the supercapacitor’s frequency response, for shorter pulse widths there will be less capacitance available than the DC capacitance. In Fig 7, consider the voltage drop due to capacitance after 10ms = 2.662V – 2.654V = 8mV. Therefore Ceff(10ms) = Discharge_Current x 10ms/Voltage drop(10ms) = 1.05A x 0.01s/0.008V = 1.3F. The voltage drop due to capacitance after 100ms = 2.662V – 2.636V = 26mV, hence Ceff(100ms) = 1.05A x 0.1s/0.026V = 4.0F. Fig 8 shows Ceff as a % of DC capacitance for the GY series of supercapacitors.

Revision 4.5, Feb 2024 

**GY SERIES DATASHEET** 

**Fig 8: Typical effective capacitance range for GY 2.7V series supercapacitors** 

For any given pulse width, T, with a constant discharge current IDISCH, the voltage drop is given by: 

Vdrop = IDISCH x ESR + IDISCH x T/Ceff(T) 

Where Ceff(T) = DC capacitance x % at time T read from Fig 8. 

Shorter pulses need less capacitance to support them, so the supercapacitors can support short pulses despite their slow frequency response. 

## **Balancing options** 

In many applications a voltage > 2.7V but ≤ 5.5V is required. For these applications 2 supercapacitor cells are connected in series in dual cell modules such as the CAP-XX GY2 series which is rated to 5.5V. 

Our experimental data shows in most cases these dual cylindrical cells modules self-balance sufficiently to ensure long life. However, under harsh operating condition, such as large temperature swing, high charge/discharge current, CAP-XX recommend the use of a balancing solution to ensure longevity. 

In the GY2 series modules there is a PCB connecting the 2 cells. The voltage between the 2 cells must be balanced. This PCB can have one of two balancing options: 

1. Option “R” as the last character in the GY2 series part number. A pair of balancing resistors are fitted, one resistor across each cell. The balancing resistors increase leakage current drawn by the module. Thus the value of the resistor should be carefully chosen by the customer during ordering. 

2. Option “N” as the last character in the GY2 series part number. No balancing is included.

Revision 4.5, Feb 2024 **GY SERIES DATASHEET** 

If the application uses a supercapacitor charging IC that has an integrated supercapacitor midpoint balancing circuit, or there is a balancing circuit on the PCB, then order 2 x GY1 cells and place them in series. This makes the midpoint available to your balancing circuit. The dimensions of 2 GY1 cells placed next to each other are the same as a shrink wrapped GY2 series cell, refer to Dimensions on page 4 of this datasheet. Refer to the Application Whitepaper on Supercapacitor Cell Balancing under the DESIGN AIDS section of the CAP-XX website, www.cap-xx.com for more information on cell balancing. 

## **Storage** 

CAP-XX recommends storing supercapacitors in their original packaging in an air conditioned room, preferably at < 30C and < 50% relative humidity. CAP-XX supercapacitors can be stored at any temperature not exceeding their maximum operating temperature but storage at continuous high temperature and humidity is not recommended and will cause premature ageing. 

- Do not store supercapacitors in the following environments: 

   - High temperature / high humidity 

   - Direct sunlight 

   - In direct contact with water, salt, oil or other chemicals 

   - In direct contact with corrosive materials, acids, alkalis or toxic gases 

   - Dusty environment 

   - In environments subjected to shock and vibration 

## **Soldering** 

When soldering it is important to not over-heat the supercapacitor to not adversely affect its performance. CAP-XX recommends that only the leads come in contact with solder and not the supercapacitor body. 

## Hand Soldering 

Heat transfers from the leads into to the supercapacitor body, so the soldering iron temperature should be < 350C soldering time should be kept to the minimum possible and be less than 4 seconds.

## **Transportation** 

All the supercapacitor cells in this datasheet store < 0.3Wh energy. The energy in watt-hours is calculated as: ½ x Capacitance x Vrated[2] /3600. The largest cell in this range is 100F, so stored energy = ½ x 100 x 2.7[2] /3600 = 0.101Wh. Under regulation UN3499 there is no restriction on shipping these supercapacitors. Their shipping description is “Electrical Capacitors” with harmonized shipping code 8532.29.0040.
