For minimum backup times of standard and vertical miniaturized series see Figs 9 and 10 (charging time ≥ 24 hours). MGA695 10 5 Figure 11 shows the backup time when a 196 DLC capacitor is discharged by a constant resistance (charging time ≥ 24 hours). The horizontal axis shows the initial value of discharge current if 5 V is connected to the capacitor via a fixed series resistor. EXAMPLE: 1 µA CORRESPONDS TO 5 MΩ AND 0.1 µA CORRESPONDS TO 50 MΩ The vertical axis shows that period of time during which the voltage drops from 5 to 2 V. backup time (s) 10 4 MLB203 10 3 4 5 2 10 10 10 -3 10 -2 10 1 102 3 Curve 1: 1.0 F, 5.5 V Curve 2: 0.47 F, 5.5 V Curve 3: 0.22 F, 5.5 V Curve 4: 0.1 F, 5.5 V Curve 5: 0.047 F, 5.5 V Voltage drop from 5.0 to 3.5 V 2 10 backup time (s) 1 2 10 3 -1 1 discharge current (mA) 10 Fig.9 Typical backup time as a function of discharge current Curve 1: 1.0 F, 5.5 V Curve 2: 0.47 F, 5.5 V Curve 3: 0.22 F, 5.5 V Curve 4: 0.1 F, 5.5 V Curve 5: 0.047 F, 5.5 V Voltage drop from 5.0 to 2.0 V by means of a fixed resistor 10-2 10 6 4 5 1 10-1 MGA696 backup time (s) 3 1 10 102 103 initial value discharge current (mA) Fig.11 Typical backup time as a function of initial discharge current 10 5 10 4 10 3 104 Curve 1: 1.0 F, 5.5 V Curve 2: 0.47 F, 5.5 V Curve 3: 0.22 F, 5.5 V Curve 4: 0.1 F, 5.5 V Curve 5: 0.047 F, 5.5 V Voltage drop: from 5.0 to 2.0 V 10-3 10-2 1 2 3 4 5 10-1 1 10 discharge current (mA) Fig.10 Typical backup time as a function of discharge current www.vishay.com 166 For technical questions contact: [email protected] Document Number: 28362 Revision: 15-Apr-08 196 DLC Double Layer Capacitors Vishay BCcomponents Table 2 TEST PROCEDURES AND REQUIREMENTS for standard and vertical miniaturized series (5.5 V; 70 °C) NAME OF TEST IEC 60384-4/ EN130300 subclause PROCEDURE (quick reference) REQUIREMENTS tensile strength; application of loading force for 10 seconds: Robustness of terminations 4.4 20 N (standard series) no breaks 5 N (vertical miniaturized series) ΔC/C: ± 10 % RI and IL ≤ spec. limit Resistance to soldering heat 4.5 solder bath; 260 °C; 5 seconds Solderability 4.6 solder bath; 235 °C; 2 seconds ≥ 75 % tinning 4.8 10 to 55 Hz; 1.5 mm; 3 directions; 2 hours per direction ΔC/C: ± 10 % RI and IL ≤ spec. limit 4.12 500 hours at 55 °C; RH 90 to 95 %; no voltage applied ΔC/C: ± 30 % RI ≤ 4 x spec. limit IL ≤ 2 x spec. limit 4.13 Tamb = 70 °C; 5.5 V applied; 1000 hours ΔC/C: ± 30 % RI ≤ 4 x spec. limit IL ≤ 2 x spec. limit 4.17 Tamb = 70 °C; no voltage applied; 1000 hours ΔC/C: ± 30 % RI ≤ 4 x spec. limit IL ≤ 2 x spec. limit 24 hours storage at room temperature after application of 5 V for 1 hour remaining voltage: ≥ 4 V step 1: reference measurement at + 20 °C of C, RI and IL step 2: measurement at - 25 °C step 3: measurement at + 20 °C step 4: measurement at + 70 °C step 5: measurement at + 20 °C ΔC/C: ± 30 % of + 20 °C value RI ≤ 5 x the + 20 °C value IL ≤ 4 x the + 20 °C value Vibration Damp heat, steady state Endurance Storage at upper category temperature Self discharge - Characteristics at high and low temperature 4.19 Document Number: 28362 Revision: 15-Apr-08 For technical questions contact: [email protected] www.vishay.com 167 Legal Disclaimer Notice Vishay Disclaimer All product specifications and data are subject to change without notice.
