738D, CT9 (CECC 30202-004)
Vishay Tansitor
Wet Tantalum Capacitors
with Glass to Tantalum Hermetic Seal,
Sintered Anode TANTALEX
®
Capacitors
FEATURES
• Hermetic glass to tantalum seal
• High CV per unit volume
• Extremely low leakage current
• Wide temperature range: - 55 to + 175°C
• 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
shock.
PERFORMANCE CHARACTERISTICS
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
recommended.
Capacitance Tolerance:
At 120 Hz, + 25°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.
