Wet Tantalum Capacitors
with Glass to Tantalum Hermetic Seal,
Sintered Anode TANTALEX® Capacitors
• Hermetic glass to tantalum seal
• High CV per unit volume
• Extremely low leakage current
• Wide temperature range: - 55 to + 175°C
Operating Temperature: - 55°C to + 85°C and with
voltage derating to two-thirds the + 85°C rating at + 125°C.
Capable of + 175°C operation at reduced voltage. Use of
Type 135D capacitors for high temperature applications is
Capacitance Tolerance: At 120 Hz, + 25°C. ± 20%
standard. ± 10%, ± 5% available as special.
DC Leakage Current (DCL Max.):
At + 25°C, + 85°C and + 125°C: Leakage current shall not
exceed the values listed in the Standard Ratings Tables.
Life Test: Capacitors are capable of withstanding a 2000
hour life test at a temperature of + 85°C or + 125°C at the
applicable rated DC working voltage.
• Improved reliability through the use of a glass-to- tantalum
true hermetic anode seal is the prime feature of the 738D
and CT9 sintered anode TANTALEX® capacitor. This
construction eliminates all internal lead welds while
retaining the strength of internal lead-welded parts.
• The construction offers outstanding resistance to thermal
• CECC 30202-004 CT9 style
This is expressed in
picofarads. The first two
digits are the significant
figures. The third is the
number of zeros to
X0 = ± 20%
X9 = ± 10%
X5 = ± 5%
DC VOLTAGE RATING
AT + 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"
(6R3 = 6.3 volts).
0 = Bare case.
2 = Outer plastic
6 = High temperature
(above + 125°C).
Packaging: The use of formed plastic trays for packaging these axial lead components is standard. Tape and reel is not recommended
due to the unit weight.
