PERFORMANCE CHARACTERISTICS (Continued)
7.1 At + 25°C, the leakage current shall not exceed
the value listed in the Standard Ratings Table.
7.2 At + 85°C, the leakage current shall not exceed 10
times the value listed in the Standard Ratings Table.
7.3 At + 125°C, the leakage current shall not exceed 12
times the value listed in the Standard Ratings Table.
8. Equivalent Series Resistance: Measurements shall
be made by the bridge method at, or referred to, a
frequency of 100 KHz and a temperature of + 25°C.
8.1 The Equivalent Series Resistance shall not exceed the
value listed in the Standard Ratings Table.
9. Life Test: Capacitors shall withstand rated DC
voltage applied at + 85°C for 2000 hours or derated
DC voltage applied at + 125°C for 1000 hours.
9.1 Following the life test, the dissipation factor and
leakage shall meet the initial requirement; the
capacitance change shall not exceed ± 10% of the
initial value.
10 Humidity Test: Capacitors shall withstand 1000 hours
at + 40°C, 90% to 95% relative humidity, with no
voltage applied
10.1 Following the humidity test, capacitance change shall
not exceed ± 10% of the initial value, dissipation factor
shall not exceed 150% of the initial requirement;
leakage currrent shall not exceed 200% of the initial
requirement at + 25°C
11. Solderability: Capacitors will meet the solderability
requirements of ANSI/J-STD-002, test B category 1.
12. Resistance to Soldering Heat: Capacitors mounted
on a substrate will withstand + 260°C for 5 seconds.
12.1 Following the resistance to soldering heat test,
capacitance, dissipation factor and DC leakage
current shall meet the initial requirement.
13. Marking: The small body area of these capacitors
does not allow elaborate marking schemes. All
required information is present on the carton or
package in which the parts are shipped; in addition,
part number, quantity and data code are indicated on
the reels.
14. Terminal Strength: Per IEC-384-3, minimum of
5N shear force.
15. Environmental: Mercury, CFC and ODS materials
are not used in the manufacture of these capacitors.
16. Flammability: Encapsulant materials meet UL94 V0
17. Capacitor Failure Mode: The predominant failure
mode for solid tantalum capacitors is increased
leakage current resulting in a shorted circuit. Capaci-
tor failure may result from excess forward or reverse
DC voltage, surge current, ripple current, thermal
shock or excessive temperature.
The increase in leakage is caused by a breakdown of
the Ta₂O₅ dielectric. For additional information on
leakage failure of solid tantalum chip capacitors, refer
to Vishay Sprague Technical Paper, “Leakage Failure
Mode in Solid Tantalum Chip Capacitors.”

2. A-C Ripple Current: The maximum allowable ripple
current shall be determined from the formula:
where,
I_rms =
P
R_ESR
P = Power Dissipation in Watts @ + 25°C as given
in the table in Paragraph Number 6.0 (Power Dissipation)
R_ESR = The capacitor Equivalent Series Resistance
at the specified frequency.
3. A-C Ripple Voltage: The maximum allowable ripple
voltage shall be determined from the formula:
V_rms = Z
or, from the formula:
P
R_ESR
where,
V_rms = I_rms x Z
P = Power Dissipation in Watts @ + 25°C as given in
the table in Paragraph Number 6.0 (Power
Dissipation).
R_ESR = The capacitor Equivalent Series Resistance
at the specified frequency.
Z = The capacitor impedance at the specified
frequency.
