Wet Tantalum Capacitors Tantalum-Case with Glass-to-Tantalum Hermetic Seal + 200�C Operation

Standard and Extended Ratings. Model 135D tantalum-case tantalum electrolytic capacitors incorporate the advantages of all the varieties of electrolytic capacitors and eliminate most of the disadvantages. These units have a 3 volt reverse voltage capability + 85�C and a higher ripple current capability than any other electrolytic type with similar combinations of capacitance and case size. Designed for the aerospace applications, this capacitor was developed under partial sponsorship of the Marshall Space Flight Center, National Aeronautics and Space Administration. The capacitors have a high resistance to damage from shock and vibration. Extended range ratings and high temperature designs are available. Model 135D capacitors are commercial equivalents of Tansitor Style; AQ, AR, HAQ, HAR, Mallory-NACC Style; TLT, TXT, THT, THX and Military Style CLR79 and CLR81, designed to meet the performance requirements of Military Specification MIL-PRF-39006/22/25. Capacitors to meet MILPRF-39006/22/25 should be ordered by part numbers shown in that specification. Life Test: Capacitors are capable of withstanding a 2000 hour life test at a temperature 125�C at the applicable rated DC working voltage. Following life test: 1. DCL, measured + 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.

Operating Temperature: + 85�C. (To + 200�C with voltage derating.) Capacitance Tolerance: At 120 Hz, � 20% standard. available as special. DC Leakage Current (DCL Max.): + 25�C and above: Leakage current shall not exceed the values listed in the Standard Ratings Tables.

306 CAPACITANCE This is expressed in picofarads. The first two digits are the significant figures. The third is the number of zeros to follow.

006 DC VOLTAGE RATING + 85�C This is expressed in volts. To complete the three-digit block, zeros precede the voltage rating. A decimal point is indicated by an "R" = 6.3 volts).

C CASE CODE See Ratings and Case Codes Table.

2 STYLE NUMBER Standard = No outer tube. 2 = Outer polyesterfilm insulation. High Temperature = No outer tube 6 = High temperaturefilm insulation (above + 125�C).

Packaging: The use of formed plastic trays for packaging this type of axial lead component is standard. Tape and reel is not recommended due to the unit weight.

*Part Numbers listed are for units with � 20% capacitance tolerance insulated capacitors. For � 10% tolerance capacitors, change the digit following the letter "X" from to "9"; for � 5%, change the digit following the letter "X" from to "5". For capacitors without outer polyester-film insulation, change the last digit in the part number from to "0". For capacitors with a high temperature insulating sleeve, change the last digit in the part number from to "6".
