Tantalum Through-Hole Capacitors – Molded Radial
T340 Molded Radial
Overview
The compact, space-saving T340 is transfer molded in
precision, with a high impact-resistant plastic that has
excellent electrical, physical and moisture-resistant
properties. The gold color plastic case permits laser
marking with outstanding permanency and legibility.
Marking is provided on the top of the case to allow visual
inspection for proper polarity and placement after insertion.
In addition, positive polarity identification is achieved by
an easily recognized molded radius on the positive end of
the case. Additionally, this physical polarity identification is
readily observed after capacitor placement as a further aid
in the prevention of possible reverse insertion. Standoffs,
located in the base of all case sizes, provide vents for air
circulation and also to allow easy removal of flux residues
from leadwire and circuit board solder joints. With very low
impedance and ESR values, the T340 features exceptionally
low DC leakage and DF characteristics. The T340 is
available in standard ±20%, ±10%, and ±5% (special order)
capacitance tolerance. T340 capacitors are highly reliable
and exhibit performance characteristics typical of military
test standards.
Benefits
Applications
• Taped and reeled per EIA Specification RS-468

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.

E(max) = √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.

Tantalum Through-Hole Capacitors – Molded Radial
T340 Molded Radial
Storage
Tantalum molded radial 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.
Tape & Reel Packaging Information
KEMET offers Solid Tantalum Capacitors fully compatible for use with automatic insertion machines for radial-lead
components. Aris Reeling meets all requirements of EIA Standard RS-468. KEMET capacitors are wound on a precision
made ARIS Reel Package. ARIS Ammo Package is also available.
