Wet Tantalum Capacitors Surface Mount, Molded Case
PERFORMANCE CHARACTERISTICS
Operating Temperature: - 55 °C to + 85 °C
(To + 125 °C with voltage derating.)
Capacitance Tolerance: At 120 Hz, + 25 °C, ± 20 %
standard, ± 10 %
DC Leakage Current (DCL Max.): At + 25 °C and above:
Leakage current shall not exceed the values listed in the
Standard Ratings Tables.
Life Test: Capacitors are capable of withstanding a 2000 h
life test at a temperature of + 85 °C or + 125 °C at the
applicable rated DC working voltage.
Following life test:
1. DCL, measured at + 85 °C rated voltage, shall not be in
excess of the original requirement.
2. The equivalent series resistance shall not exceed 150 %
of the initial requirement.
3. Change in capacitance shall not exceed 10 % from the
initial measurement.
FEATURES
• Terminations: standard tin/lead (SnPb),
100 % tin (RoHS compliant) terminations
available
• Very high capacitance, 10 µF to 470 µF
6 V to 125 V, - 55 °C to + 125 °C
• Very low ESR
• High ripple current capability
• Low DCL
• Model M34 wet tantalum electrolytic chip capacitors
incorporate the advantages of all the varieties of
electrolytic capacitors and eliminate most of the
disadvantages. These units have a transient reverse
voltage capability and a higher ripple current capability
than any other electrolytic type with similar combinations of
capacitance and case size.
• Compliant to RoHS directive 2002/95/EC
APPLICATION NOTES
a) No continuous reverse voltage permissible.
b) Transient reverse voltage surges are acceptable under
the following conditions:
The peak reverse voltage does not exceed 1.5 V and the
peak current times the duration of the reverse transient
does not exceed 0.05 A. In addition, the repetition
frequency of the reverse voltage surge is less than 10 Hz.
c) The peak of the applied AC ripple and the applied DC
voltage must not exceed the DC voltage rating of
the capacitor.
