Standard tolerances are 20%, 10%, and 5%. Closer tolerances may be produced upon special order and after agreement upon measurement conditions. Typical variation of capacitance with respect to temperature is illustrated in Figure 1a. The capacitance of solid tantalum capacitors decreases with frequency, as shown in Figure 1b. shown in Figure 2. Dissipation factor loses its importance as a measurement parameter at higher frequencies, where impedance and ESR are the normal parameters of concern. 20.0 Multiplier of 120 Hz D. F. Introduction -- The following section is devoted to general information of assistance in the application of T240 Series capacitors. Space does not permit a complete discussion of all technical aspects, and further information on specific problems may be obtained through KEMET sales representatives. 10.0 1.0 100 1K 10K Frequency - Hertz Capacitance Value Fig. 2 Typical Behavior of dissipation factor as a function of Frequency @ 25 C +20 +10 0 -10 -20 -80 -60 -40 -20 0 +20 +40 +60 +80 +100 +120 Operating Temperature C Multiplier of 120Hz Capacitance Fig. 1a Typical capacitance with temperature DC Leakage Current -- The DC Leakage current limits of Table 1 for T240 Series capacitors are the lowest generally specified in the solid tantalum industry. Even lower leakage currents are available on special order. Low leakage current, aside from its intrinsic value, is an indication of anode quality. DC leakage current as a function of temperature is represented by the typical curve in Figure 3, while similar information pertaining to leakage behavior with respect to voltage is contained in Figure 4. 1.0 0.9 100 1K 10K Frequency - Hertz Fig. 1b Typical Variation of capacitance with frequency @ 25 C Dissipation Factor -- Dissipation factor is defined as the ratio of equivalent series resistance to capacitive reactance at a specified frequency: D= Where R XC = 2fCR R = equivalent series resistance in ohms D = dissipation factor XC = capacitive reactance in ohms C = series capacitance in farads f = frequency in Hertz Multiplier of DC Leakage Current Reference 1.0 at 120Hz 10.0 Reference 1.0 at + 25C 1.0 0.1 -60 -40 -20 0 +20 +40 +60 +80 +100 +125 Operating Temperature -C Unless otherwise stated, a standard frequency of 120 Hz is used for both dissipation and capacitance measurements.

Operation at 125C with 2/3 rated voltage applied gives equivalent results, and voltage may be derated linearly between these two points. Unlike wet electrolytic capacitors, solid tantalum capacitors may be operated continuously at any voltage from zero to the maximum rating without adverse effects. Operation at voltage below nameplate improves reliability, while subsequent operation at a higher voltage will not be affected by prior low voltage use. Multiplier of DC Leakage Current 1.0 Expected reliability factors for voltages and temperatures other than the rated conditions may be found in Figure 5. Since T240 Series capacitors are supplied with a predetermined failure rate under rated conditions, reliability under use conditions may be estimated with this nomograph. Circuit Impedance -- Failure rates are affected by temperature and voltage as described in Figure 5 and also by the circuit impedance seen by the capacitor. Traditionally, application advice for solid tantalum capacitors suggested an impedance of 3 ohms or higher per applied volt. This advice was later found to be unnecessarily conservative, and the factors in Table II, are based on 0.1 ohm per volt as the unity failure rate multiplier. 0.1 TABLE II 0.01 0.001 0 10 20 30 40 50 60 70 80 90 100 Percentage of Rated Voltage 110 Circuit Impedance, Ohms per Volt 0.1 0.2 0.4 0.6 0.8 1 2 3 Failure Rate Multiplying Factor 1.0 0.8 0.6 0.4 0.3 0.2 0.1 0.07 Fig. 4 Typical effect of voltage upon leakage current 125 1.2 10 3 120 1.1 10 2 110 85C Rating 1.0 T1 90 F1 F3 F2 10 -1 85 T2 80 10 -2 Connect the temperature and applied voltage ratio of interest with a straight edge.

The curves of Figure 6 are typical of the capacitor values noted, with measurements being made by contacting lead wires 1/4 inch from the ends of the capacitor cases. Since ESR decreases with frequency, AC performance at higher frequencies is considerably better than would be predicted from the 120 Hz ratings. Capacitor Impedance -- The relationship between impedance and frequency at various voltage ratings is illustrated with typical curves in Figure 6. Impedance declines with decreasing capacitive reactance, but ESR becomes dominant before the self-resonant point is reached, producing the typical damped curves. Finally, impedance increases as inductance of the lead wire and other capacitor elements dominates. Obviously, high frequency impedance is directly influenced by the length of lead wire and general mounting configuration. The typical curves of Figure 6 include 1/4 inch of lead wire at each end of the capacitor. 30 25 T F V 0.1 Fig.5 Reliability Alignment Chart 14 KEMET Electronics Corporation * P.O.

However, some short duration reversal is permissable as shown in Table IV. Fig. 6 Typical Behavior of Impedance and ESR as a function of frequency @ 25C TABLE IV AC Ripple -- Permissable AC ripple voltage is related to the rated voltage, the ESR of the capacitor, and the power dissipation capability of a particular case size: 1. The positive peak AC voltage plus the DC bias voltage (if any), must not exceed the rated voltage. 2. The negative peak AC voltage, in combination with the bias voltage (if any), must not exceed that allowable (see Reverse Voltage). 3. The power dissipated in the equivalent series resistance of the capacitor must not exceed the limits specified in Table III. The power dissipated may be calculated from the following: 2 P= ER Z2 Where E = ripple voltage across capacitor in rms volts Z = capacitor impedance in ohms at the specified frequency. R = equivalent series resistance in ohms Ripple voltage, as limited by power dissipation, may be determined as follows: E max (25C) = Z P max R Permissible Reverse Voltage Temp. % of Forward C Rated Voltage 25 15 85 5 125 1 Surge Current -- Surge current testing is performed to provide resistance from damage due to circuit transients. This test, employing total DC circuit resistance of 1.0 max, exclusive of the capacitor, is described on Page 21. Shelf Life -- Shelf life is particularly difficult to define for the solid tantalum capacitor. Extended periods of storage at high temperature will cause some small change in leakage current which usually returns to normal upon short time application of working voltage. Storage at low temperatures causes little or no degradation of leakage current. Long-term studies of capacitance and dissipation factor shift for as long as 45,000 hours indicate only minor variations (usually less than 2%) in these parameters. Installation -- Mounting procedures should not place undue strain on terminals, particularly the positive end with its glass-metal seal. Attention to soldering technique should avoid excessive heat transfer which might remelt the capacitor's internal solder and cause loss of hermeticity or short circuits. Potting materials should not produce excessive curing exotherms or shrinkage pressures. KEMET Electronics Corporation * P.O. Box 5928 * Greenville, S.C. 29606 * 864/963-6300 15 (R)
