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
which may be applied is limited by two criteria:
1. The positive peak AC voltage plus the DC bias voltage,
if any, must not exceed the DC voltage rating of the
capacitor.
2. The negative peak AC voltage in combination with
bias voltage, if any, must not exceed the allowable limits
specified for reverse voltage. See the Reverse Voltage
section for allowable limits.
The maximum power dissipation by case size can be
determined using the table at right. The maximum power
dissipation rating stated in the table must be reduced with
increasing environmental operating temperatures. Refer to
the table below for temperature compensation requirements.

Reverse Voltage
Solid tantalum capacitors are polar devices and may be permanently damaged or destroyed if connected with the wrong
polarity. The positive terminal is identified on the capacitor body by a stripe plus in some cases a beveled edge. A small
degree of transient reverse voltage is permissible for short periods per the table. The capacitors should not be operated
continuously in reverse mode, even within these limits.

Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for reflow
solder processes.
Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reflow solder processes.
Density Level C: For high component desity product applications. Before adapting the minimum land pattern variations the user should perform
qualification testing based on the conditions outlined in IPC standard 7351 (IPC–7351).

Tantalum Surface Mount Capacitors – Standard Tantalum
T490 Series Commercial Grade MnO 2
Soldering Process
KEMET’s families of surface mount capacitors are compatible
with wave (single or dual), convection, IR, or vapor phase
reflow techniques. Preheating of these components is
recommended to avoid extreme thermal stress. KEMET's
recommended profile conditions for convection and IR
reflow reflect the profile conditions of the IPC/J–STD–020D
standard for moisture sensitivity testing. The devices can
safely withstand a maximum of three reflow passes at these
conditions.
Please note that although the X/7343–43 case size can
withstand wave soldering, the tall profile (4.3 mm maximum)
dictates care in wave process development.

Storage
Tantalum chip capacitors should be stored in normal working environments. While the chips themselves are quite robust in
other environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres,
and long term storage. In addition, packaging materials will be degraded by high temperature – reels may soften or warp
and tape peel force may increase. KEMET recommends that maximum storage temperature not exceed 40°C and maximum
storage humidity not exceed 60% relative humidity. Temperature fluctuations should be minimized to avoid condensation on
the parts and atmospheres should be free of chlorine and sulphur bearing compounds. For optimized solderability chip stock
should be used promptly, preferably within three years of receipt.

Note 5
1. The embossment hole location shall be measured from the sprocket hole controlling the location of the embossment. Dimensions of embossment
location and hole location shall be applied independent of each other.
2. The tape, with or without components, shall pass around R without damage (see Figure 4).
3. If S1 < 1.0 mm, there may not be enough area for cover tape to be properly applied (see EIA Standard 481–D, paragraph 4.3, section b).
4. B1 dimension is a reference dimension for tape feeder clearance only.
5. The cavity defined by A0, B0 and K0 shall surround the component with sufficient clearance that:
(a) the component does not protrude above the top surface of the carrier tape.
(b) the component can be removed from the cavity in a vertical direction without mechanical restriction, after the top cover tape has been removed.
(c) rotation of the component is limited to 20° maximum for 8 and 12 mm tapes and 10° maximum for 16 mm tapes (see Figure 2).
(d) lateral movement of the component is restricted to 0.5 mm maximum for 8 mm and 12 mm wide tape and to 1.0 mm maximum for 16 mm tape (see
Figure 3).
(e) see Addendum in EIA Standard 481–D for standards relating to more precise taping requirements.

Packaging Information Performance Notes
1. Cover Tape Break Force: 1.0 Kg minimum.
2. Cover Tape Peel Strength: The total peel strength of the cover tape from the carrier tape shall be:
Tape Width
Peel Strength
8 mm
0.1 to 1.0 Newton (10 to 100 gf)
12 and 16 mm
0.1 to 1.3 Newton (10 to 130 gf)
The direction of the pull shall be opposite the direction of the carrier tape travel. The pull angle of the carrier tape shall be
165° to 180° from the plane of the carrier tape. During peeling, the carrier and/or cover tape shall be pulled at a velocity of
300 ±10 mm/minute.
3. Labeling: Bar code labeling (standard or custom) shall be on the side of the reel opposite the sprocket holes. Refer to EIA
Standards 556 and 624.
