from specimens : Not applicable
b. Method of mounting: Normal means
c. Test condition letter: F (2000 hours, +72 hrs, -

Conditions Aor D, and C
18. High Temperature Capacitors - T197
and T198 Series
The voltage derating for these capacitors begins at
+85°C, as with all other tantalum capacitors. There will
be a linear derating between 100% at +85°C and 2/3
(67%) at +125°C. For the 200°C rated parts, the volt-
age rating shall be 50%.
For reverse voltage rating, the 3 VDC shall apply to
all temperatures up to +85°C. From +85°C to +125°C,
the reverse voltage rating shall be 2 VDC. From
+125°C to +200°C, the reverse voltage rating shall be
1.0 VDC.
19.Mounting
Wet tantalum capacitors will pass the Resistance to
Soldering Heat Test of MIL-STD-202, Method 210,
Condition C. This test simulates wave solder of topside
board mount product. This demonstration of resistance
to solder heat is in accordance with what is believed to be
the industry standard. More severe treatment must be
considered reflective of an improper soldering process.
