type edl , electric double layer supercapacitors ultra high capacitance, small case size options type edl electric double layer supercapacitors ofer extremely high capacitance values (farads) in a variety of packaging options that will satisfy, low profle, 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. highlights - unlimited charging and discharging capability - recycling is not necessary - long life - 15 years - low esr - will extend battery life up to 1.6 times - first class performance with economy pricing specifcations operating temperature range C25 oc to +85 oc rated voltage range 2.1 vdc to 5.5 vdc capacitance range 0.022 f to 70 f how to select an electric double layer capacitor estimated initial backup time 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. 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-of voltage set by the user after applying the applications 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 a in an ambient temperature of +40 oc. the memory rtc cut-of voltage is 2.0 vdc. using minimum capacitance, calculate the back-up time as follows: t = cv ? i = c[v0C(i?r)Cv1] ? (i+il) c = 1.0 fC20% = 0.8 f, r=50 , v0=5 v, v1=2 v, i=10 a therefore, t = 0.8 (5C0.0005C2) ? ((10+2) x10^C6)= 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. cde cornell dubilier ? 1605 e. rodney french blvd. ? new bedford, ma 02744 ? phone: (508)996-8561 ? fax: (508)996-3830 series maximum operating (discharge) current 0.047 f 0.1 f to 0.33 f 0.47 f to 1.5 f 3.3 f to 4.7 f 10 f to 50 f sg, sd, nf 200 a 300 a 1 ma C C f 200 a 300 a 300 a C C en C 10 a C C C hw C C C 300 ma 1 a 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 () at 1 khz
life design 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) lifetime the minimum rated life at 85 oc with 5.5 vdc applied is 1000 hours with maximum permitted end-of-life capacitance change of C30% and a 4 times increase in internal resistance. temperature factor to determine the efect of temperature on expected life of a supercapaci - tor, 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 = 2^4.5 = 22.6 times. the tempera - ture 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 efect 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 than 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 rohs compliant type edl , electric double layer supercapacitors ultra high capacitance, small case size options cde cornell dubilier 1605 e. rodney french blvd. new bedford, ma 02744 phone: (50)6-561 fax: (50)6-330 current collector electrolyte separator activated carbon current collector resistor to charge electric double layer capacitor resistor to move ions electric double layer supercapacitor construction
