Tantalum Through-Hole Capacitors – Molded Radial
T370 & T378 Micron MIL-PRF-49137/6 (CX06 Style)
Overview
The T370 and T378 Micron MIL-PRF-49137/6 (CX06 Style)
capacitors are available in a variety of case styles and
sizes. These capacitors are designed to operate from
–55°C to +85°C at full voltage and to +125°C with derating.
The KEMET Micron is qualified under MIL-PRF-49137/6 as
military styles CX06 (T378 ).
The T370 capacitor is encapsulated in a molded, goldcolored epoxy. This encasement technique allows maximum
utilization of circuit board real estate, with precisely
centered leads in a microminiature case.
These molded packages also provide significant
improvements in overall dimensional consistency, as
well as lead wires precisely spaced to within 0.010
inches (0.25 mm). With KEMET's new molded packaging
design, these capacitors can now be marked using
a laser printing technique. The KEMET laser marking
system ensures legibility and permanency while offering a
complete alphanumeric print format. Laser print meets all
requirements of the Resistance to Solvents Test, Method 215
of MIL-STD-202.

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)

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.
