COMPONENT PERFORMANCE CHARACTERISTICS
(con’t.)
20. Surge Current
All conventional reliability testing is conducted
under steady-state DC voltage. Experience indi-
cates that AC ripple, within the limits prescribed,
has little effect on failure rate. Heavy surge cur-
rents are possible in some applications, howev-
er. Circuit impedance may be very low (below the
recommended 0.1 ohm/volt) or there may be dri-
ving inductance to cause voltage “ringing.” Surge
current may appear during turn-on of equipment,
for example. Failure rate under current-surge
conditions may not be predictable from conven-
tional life test data.
Capacitors are capable of withstanding a 4 ±1
second charge of rated voltage (±2%) through a
total circuit resistance (excluding the capacitor) of
1 ±0.2 ohms at +25°C, followed by a 4 ±1 second
discharge to a voltage below 1% of the rated volt-
age. This cycle is repeated consecutively three
(3) times. Post test performance:
a. Capacitance — within ±5% of initial value
b. DC Leakage — within initial limit
c. Dissipation Factor — within initial limit
100% production surge current testing is per-
formed on all Tantalum Chip series for case sizes
C, D, E, X, U, V. The total test circuit resistance
is
≤
0.5 ohms. The applied voltage is 75% of
rated voltage for all series except the T495 and
T510 which are surged at 100% of rated voltage.
Four surge cycles are applied. Parts not capable
of surviving this test are removed at subsequent
electrical screening. See T493 Series on page 22
for specific surge options.
