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:

%

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.

* Pb containing terminations are not RoHS compliant, exemptions may apply
