Type EDL , Electric Double Layer Supercapacitors
Ultra High Capacitance, Small Case Size Options
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 Capacitor
Estimated Initial Backup Time
Select the optimum supercapacitor according to applied
current
Back-up time for Type EDL Electric Double Layer Supercapacitors decreas-
es with use and over time especially when the current is large or operat-
ing at high temperature. Be sure to specify extra back-up time initially to
allow for product changes.
The internal resistance of the supercapacitor prevents drawing high
discharge currents. Select the supercapacitor capable of delivering the
peak current a t switchover to back-up mode using t he 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) x10^–6)= 55 hours
And thus the initial back-up time is 55 hours. After 1000 hours,
calculate the back-up time will drop to about 38 hours.
t: Back-up time (s)
C: Capacitance of Type EDL (F)
V 0 : Applied voltage (V)
V 1 : Cut-off voltage (V)
i: Current during back-up (A)
i L : Leakage current (A)
R: Internal resistance (Ω) at 1 kHz
