Tantalum Surface Mount Capacitors – High Reliability
T495 High Reliability Alternative Surge Robust,
Low ESR MnO2 DLA Drawing 95158
Overview
The low ESR, surge-robust High Reliability Series
(HRA) T495 is designed for demanding applications
that require high surge current and high ripple current
capability. This T495 is approved for DLA Drawing 95158,
incorporating an intensive testing and screening protocol
that is customizable depending on specific customer
requirements. This series offers several advantages
such as low ESR, high ripple current capability, excellent
capacitance stability, and improved resistance to high in-rush
currents. These benefits are achieved through a combination
of proprietary design, materials, and process parameters, as
well as high-stress, low impedance electrical conditioning
performed prior to screening.
Benefits
• Approved for DLA Drawing 95158
• Meets or exceeds EIA standard 535BAAC
• Taped and reeled per EIA 481
• High surge current capability
• Optional gold-plated terminations
• High ripple current capability
• 100% surge current test
• 100% steady-state accelerated aging

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.

Using the Pmax of the device, the maximum allowable rms
ripple current or voltage may be determined.
I(max) = √Pmax/R
E(max) = Z √Pmax/R
I = rms ripple current (amperes)
E = rms ripple voltage (volts)

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 density 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 – High Reliability
T495 High Reliability Alternative Surge Robust, Low ESR MnO2 DLA Drawing 95158
Soldering Process
The KEMET 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.

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.

(d) lateral movement of the component is restricted to 0.5 mm maximum for 8 mm and 12 mm wide tape (see Figure 3).
(e) see Addendum in EIA Standard 481–D for standards relating to more precise taping requirements.
