Wet Tantalum Capacitors Surface Mount, Molded Case
FEATURES
* Terminations: standard tin/lead (SnPb), 100 % tin (RoHS compliant) terminations available * Very high capacitance, 10 F to 470 F 6 V to 125 V, - 55 C to + 125 C * Very low ESR * High ripple current capability
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.
* 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.

MOUNTING
Due to the size and weight of these capacitors, we recommend that a supplemental mounting restraint to be used in printed circuit board attachment in addition to the reflowed solder. One recommendation is to use an adhesive such as defined in the J-STD-001DS. This is the Space Application Electronic Hardware Addendum to J-STD-001 (Requirements for Solder Electrical and Electronic Assemblies).
