CDE EDLNF155B5R5C Electric double layer supercapacitor Datasheet

TYPE EDL Electric Double Layer Supercapacitors
Ultra High Capacitance, Small Case Size Options
RoHS Compliant
Type EDL electric double layer supercapacitors offer
extremely high capacitance values (farads) in a variety of
packaging options that will satisfy, low profile, surface
mount, through hole and high density assembly requirements. The EDL is a cut above the standard electrolytic
capacitor in that it can act as a battery without having
to deal with the environmental or hazardous material
issues that batteries entail.

How to Select an Electric Double Layer Supercapacitor
Estimated initial back-up time
Back-up time for Type EDL Electric Double Layer Supercapacitors decreases with use and over time
especially when the current is large or operating at high temperature. Be sure to specify extra back-up
time initially to allow for product changes.
Select the optimum supercapacitor according to applied current.
The internal resistance of the supercapacitor prevents drawing high discharge currents. Select the
supercapacitor capable of delivering the peak current at switchover to back-up mode using the following table.

Back-up Time Example
Back-up time is the time it takes for the applied voltage to decay to the cut-off voltage set by the user
after applying the application’s maximum voltage at application maximum temperature.
Example: An F Type EDL, P/N EDLF105B5R5C (Rated at 5.5 V, 1.0 F) is charged to 5.0 Vdc. The circuit
requirement is such that it must maintain a memory circuit with a current drain of 10 µA in an ambient
temperature of +40 ºC. The memory RTC cut-off voltage is 2.0 Vdc.
Using minimum capacitance, calculate the back-up time as
follows:
t = CΔV ⁄ I = C[V0–(i•R)–V1] ⁄ (i+iL)
C = 1.0 F–20% = 0.8 F, R=50 Ω, V0=5 V. V1=2 V, i=10 µA
Therefore,
t = 0.8 (5–0.0005–2) ⁄ (10+2) ⁄ 10–6 = 55 hours
And thus the initial back-up time is 55 hours. After 1000 hours,
t: Back-up time (s)
C: Capacitance of Type EDL (F)
V0: Applied voltage (V)
V1: Cut-off voltage (V)
i: Current during back-up (A)
iL: Leakage current (A)
R: Internal resistance (Ω) at 1 kHz
Life Design for Electric Double Layer Supercapacitors
Type EDL supercapacitors have a useful lifetime that decreases with increasing operating temperature,
humidity, applied-voltage, current and backup-time requirements.
Expected lifetime is the product of four factors:
Expected Life = (Lifetime)•(Temperature Factor)•(Voltage Factor)•(Moisture Factor)

TYPE EDL Electric Double Layer Supercapacitors
Lifetime
The minimum rated life at 85 ºC with 5.5 Vdc applied is 1000 hours with maximum permitted end-of-life
change of –30% capacitance and a 4 times increase in internal resistance.
Temperature Factor
To determine the effect of temperature on expected life of a supercapacitor, use the fact that expected
lifetime doubles for each 10 ºC that the operating temperature is reduced. As an illustration, at 85 ºC
and full voltage the rated lifetime is 1000 hours. So, at 40 ºC the expected lifetime would be multiplied
by 2(85-40)/10 = 24.5 = 22.6 times. The Temperature Factor is 22.6, and for 1000-h, 85 °C rated life, the
expected 40 °C life would be 22600 hours.
Voltage Factor
The rate of change of capacitance decreases with decreasing applied voltage. The effect on life extension is roughly proportional to the voltage derating, e.g., 5 V applied to 5.5 V rated supercapacitors
extends the life 1.1 times.
Moisture Factor
Expected life of these supercapacitors is considerably shortened by operation in high humidity. The
applications discussed here assume that the relative humidity is no more that 50%.
Expected Life Example
So, for a 5.5 V supercapacitor at 40 °C charged to 5.V in less than 50% RH the expected life is
Expected Life = (Lifetime) (Temperature Factor) (Voltage Factor) (Moisture Factor)
= (1000 h) (22.6) (1.1) (1)
= 24800 hours
= 2.8 years
