Tantalum Through-Hole Capacitors – Radial Dipped
T368 UltraDip II
Overview
The KEMET T368 is manufactured according to the
requiarements of MIL-PRF-49137, while maintaining all the
performance characteristics of the UltraDip II. Performance
characteristics meet or exceed the requirements of MILPRF-49137. In addition to the standard UltraDip II process
testing, all products supplied to MIL-PRF-49137 are sampled
on a lot-by-lot basis for Group A and Group B inspection to
ensure compliance. Product supplied per MIL-PRF-49137
also receives an additional post-process burn-in for at
least two hours under accelerated voltage stress in excess
of 125% of DC rated voltage. This post-process burn-in is
equivalent to 200 hours under rated conditions.
Benefits

Ripple Current/Ripple Voltage
Permissible AC ripple voltage and current are related to
equivalent series resistance (ESR) and the power dissipation
capabilities of the device. Permissible AC ripple voltage that
may be applied is limited by following criteria:
1. Dissipated power must not exceed the limits specified
for the Series.
2. The positive peak AC voltage plus the DC bias voltage,
if any, must not exceed the DC voltage rating of the
capacitor.
3. The negative peak AC voltage in combination with
bias voltage, if any, must not exceed the allowable limits
specified for reverse voltage.
Thermal capacities for the various case sizes have been
determined empirically and are listed below. The “ripple
voltage” permissible may be calculated from the impedance
and ESR data shown in the respective product section.

Using the P max of the device, the maximum allowable rms
ripple current or voltage may be determined.
I(max) = √P max/R
E(max) = Z √P max/R
I = rms ripple current (amperes)
E = rms ripple voltage (volts)
P max = maximum power dissipation (watts)
R = ESR at specified frequency (ohms)
Z = Impedance at specified frequency (ohms)

Optimum Solder Wave Profile
Mounting
All encased 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. The above figure is a recommended solder wave profile for both axial and radial leaded solid tantalum
capacitors.

Storage
Tantalum molded radial/axial capacitors should be stored in normal working environments. KEMET recommends that
maximum storage temperature not exceed 40°C and maximum storage humidity not exceed 60°C RH. Storage at high
temperature may cause a small, temporary increase in leakage current (measured under standard conditions), but the
original value is usually restored within a few minutes after application of rated voltage. Storage at high humidity may
increase capacitance and dissipation factor. Solderability will be degraded by exposure to high temperatures, high humidity,
corrosive atmospheres, and long term storage. For optimized solderability capacitors stock should be used promptly,
preferably within three years of receipt.
