**DMF3X5R5J204M3DTA0 DATASHEET** 

## **Definition of Terms** 

In its simplest form, the Equivalent Series Resistance (ESR) of a capacitor is the real part of the complex impedance. In the time domain, it can be found by applying a step discharge current to a charged cell as in Fig. 1. In this figure, the supercapacitor is pre-charged and then discharged with a current pulse, I =1.1A for duration 0.01 sec. 

**Fig 1: Effective capacitance, instantaneous capacitance and ESR for DMF3X5R5J204M3DTA0** 

The ESR is found by dividing the instantaneous voltage step (∆V) by I. In this example = (5.49V5.375V)/1.16A = 99mΩ. 

The instantaneous capacitance (Ci) can be found by taking the inverse of the derivative of the voltage, and multiplying it by I. 

The effective capacitance for a pulse of duration tn, Ce(tn) is found by dividing the total charge removed from the capacitor (∆Qn) by the voltage lost by the capacitor (∆Vn). For constant current Ce(tn) = I x tn/Vn. Ce increases as the pulse width increases and tends to the DC capacitance value as the pulse width becomes very long (~10 secs). After 2msecs, Fig 1 shows the voltage drop V2ms = (5.375 V – 5.334V) = 41mV. Therefore Ce(2ms) = 1.16A x 2ms/41mV = 56.6mF. After 10ms, the voltage drop = 5.375 V – 5.265V = 110mV. Therefore Ce(10ms) = 1.16 A x 10ms/110mV = 105mF. The DC capacitance of DMF3X5R5J204M3DTA0 = 0.2 F.  Note that ∆V, or I*R drop, is not included because very little charge is removed from the capacitor during this time. Ce shows the time response of the capacitor and it is useful for predicting circuit behaviour in pulsed applications.

## **Measurement of DC Capacitance** 

**Fig 2: Measurement of DC Capacitance for a DMF3X5R5J204M3DTA0** 

Fig 2 shows the measurement of DC capacitance by drawing a constant 100mA current from a fully charged supercapacitor and measuring the time taken to discharge from 80% to 40% of Vrated. In this case, C = 0.096A x 4.73s /(4.4-2.2)V = 206mF, which is within the 200mF +/- 20% tolerance for a DMF3X5R5J204M3DTA0 cell. 

## **Measurement of ESR** 

**Fig 3: Measurement of ESR for a DMF3X5R5J204M3DTA0** 

Fig 3 shows DC measurement of ESR by applying a step load current to the supercapacitor and measuring the resulting voltage drop. CAP-XX waits for a delay of 50µs after the step current is applied to ensure the voltage and current have settled. In this case the ESR is measured as 95.4mV/1.1A = 86.7mΩ.

**DMF3X5R5J204M3DTA0 DATASHEET** 

## **Effective Capacitance** 

**Fig 4: Effective Capacitance** 

Fig 4 shows the effective capacitance for the DMF3X5R5J204M3DTA0 @ 23°C. This shows that for a 1msec PW, you will measure 10% of DC capacitance or 20mF. At 10msecs you will measure 43% of the DC capacitance, and at 100msecs you will measure 80% of DC capacitance. Ceffective is a time domain representation of the supercapacitor's frequency response. If, for example, you were calculating the voltage drop if the supercapacitor was supporting 1A for 10msecs, then you would use the Ceff(10msecs) = 43% of DC capacitance = 86mF, so Vdrop = 1A x ESR + 1A x duration/C = 1A x 105mΩ + 1A x 10ms / 86mF = 221mV. 

## **DC Capacitance variation with temperature** 

**Fig 5: Capacitance change with temperature** 

Fig 6 shows that DC capacitance is approximately constant with temperature.

## **RMS Current** 

**Fig 7: Temperature rise in DMF3X5R5J204M3DTA0 with RMS 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, 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 7 shows the increase in temperature as a function of RMS current. From this, the maximum RMS current in an application can be calculated, for example, if the ambient temperature is 40C, and the maximum desired temperature for the supercapacitor is 70C, then the maximum RMS current should be limited to 3.7A, which causes a 30C temperature increase.

## **Storage** 

CAP-XX recommends storing supercapacitors in their original packaging in an air-conditioned room at < 30C and < 60% 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 

## **Cautions before use** 

CAP-XX supercapacitors are “burned in” during production, and have a defined polarity, as shown by the positive terminal marked on the face of the product. Reversing the polarity of the device will not damage the device but may cause a rise in the ESR and will void the warranty. Please verify the orientation of the supercapacitor in accordance with the product markings before assembly. 

CAP-XX supercapacitors are heat-sensitive. Over-heating of the supercapacitor may result in a degradation of performance and useful life. 

CAP-XX supercapacitors must only be used within their rated voltage range. Over-voltage may cause swelling and eventually, product failure. 

CAP-XX supercapacitors are fully discharged when shipped. Devices should be handled and soldered in a discharged state. 

## **Soldering and Assembling** 

CAP-XX supercapacitors are designed for direct soldering onto the PCB. Soldering the terminals to the PCB will ensure the highest contact reliability and lowest contact resistance. Do NOT solder directly to the device casing. This will cause permanent internal damage to the supercapacitor. 

CAP-XX supercapacitors are NOT SUITABLE for infrared reflow soldering, hot-air reflow soldering, or wave soldering. They should be mounted as a secondary operation, using a manual soldering iron, a hot bar soldering jig, conductive adhesive, ultrasonic welding or laser welding. 

CAP-XX recommends the use of a water-soluble flux, or a no-clean (low residue) flux, and low temperature solder compounds. 

Please solder under the following conditions: 

- Solder Type: Resin flux cored solder wire (ø1.2mm) 

- Solder: Lead-free solder: Sn-3Ag-0.5Cu 

- Soldering iron temperature at 350°C±10°C 

- Solder iron wattage: 70W or less 

- Soldering time: 3 to 4sec. 

- The same terminal should be soldered 3 or less times. 

If a hot-air gun is used to reflow the solder during a re-mount or de-mount, care must be taken to prevent excessive heating of the package adjacent to the solder terminals. Allow at least 15 sec between successive soldering attempts for the device to cool down. 

Please consult CAP-XX if you wish to wash the device after soldering.
