Product Safety Information Datasheet
Material Data and Handling
This should be read in conjunction with the Product Datasheet.
Failure to observe the ratings and the information on this sheet
may result in a safety hazard.
1. Material Content
Solid Tantalum and OxiCap® capacitors do not contain
liquid hazardous materials.
The operating section contains:
Tantalum/Niobium
Graphite/carbon
Tantalum/Niobium oxide
Conducting paint/resins
Manganese dioxide
Fluoropolymers (not TAC)
The encapsulation contains:
TAC - epoxy molding compound, solder/tin coated terminal
pads
TAJ, TMJ, TPS, TPM, TRJ, TRM, TAW, TLJ, TLN, TCJ, TCM,
TCN, NLJ, NOJ, NOS and NOM - epoxy molding compound,
tin/solder coated terminal pads
THJ - may contain Antimony trioxide and Bromide compounds
as fire retardants.
TAP - solder, solder coated terminal wires, epoxy dipped resin
The capacitors do not contain PBB or PBBO/PBBE. The solder
alloys may contain lead.
2. Physical Form
These capacitors are physically small and are either rectangular
with solderable terminal pads, or cylindrical or bead shaped with
solderable terminal wires.
3. Intrinsic Properties
Operating
Both Tantalum and OxiCap® capacitors are polarized devices
and operate satisfactorily in the correct d.c. mode. They will
withstand a limited application of reverse voltage as stated in the
datasheets. However, a reverse application of the rated voltage
will result in early short circuit failure and may result in fire or
explosion. Consequential failure of other associated components
in the circuit e.g. diodes, transformers, etc. may also occur. When
operated in the correct polarity,a long period of satisfactory
operation will be obtained but failure may occur for any of the
following reasons:
• normal failure rate
• temperature too high
• surge voltage exceeded
• ripple rating exceeded
• reverse voltage exceeded
If this failure mode is a short circuit, the previous conditions
apply. If the adjacent circuit impedance is low, voltage or
current surges may exceed the power handling capability of the
capacitor. For this reason capacitors in circuits of below 1Ω/V
should be derated by minimum 50% for tantalum and 20% for
OxiCap®. Precautions should be taken to prevent reverse
voltage spikes. Where capacitors may be subjected to fast
switched, low impedance source voltages, the manufacturers
advice should be sought to determine the most suitable
capacitors for such applications.
Non-operating
Both Tantalum and OxiCap® capacitors contain no liquids or
noxious gases to leak out. However, cracking or damage to the
encapsulation may lead to premature failure due to ingress of
material such as cleaning fluids or to stresses transmitted to the
tantalum anode.

4. Fire Characteristics
Primary
Any component subject to abnormal power dissipation may
• self ignite
• become red hot
• break open or explode emitting flaming or red hot
material, solid, molten or gaseous.
Fumes from burning components will vary in composition
depending on the temperature, and should be considered to be
hazardous, although fumes from a single component in a well
ventilated area are unlikely to cause problems.
Secondary
Induced ignition may occur from an adjacent burning or red hot
component. Epoxy resins used in the manufacture of capacitors
give off noxious fumes when burning as stated above. Wherever
possible, capacitors comply with the following:
BS EN 60065
UL 492.60A/280
LOI (ASTM D2863-70) as stated in the datasheets.
5. Storage
AVX Tantalum dielectric chip capacitors are unaffected by the following storage condition for 2 years:
Temperature: -10°C – +50°C
Humidity: 75% RH maximum
Atmospheric pressure: 860 mbar ~ 1060mbar
Tantalum and OxiCap® capacitors exhibit a very low random failure rate after long periods of storage and apart from this there are
no known modes of failure under normal storage conditions. All
capacitors will withstand any environmental conditions within
their ratings for the periods given in the detail specifications.
Storage for longer periods under high humidity conditions may
affect the leakage current of resin protected capacitors.
Solderability of solder coated surfaces may be affected by storage of excess of 2 years. If F-series capacitors should be stored
more than 1 year please contact AVX for advice.
6. Moisture Sensitivity Level
MSL is defined in J-STD-020. It is applicable to non-hermetic
surface mount devices, and is focussed on parts in plastic
packages.
The basic concept is that a plastic package may contain moisture, which can become a high pressure vapour during solder
reflow. If this occurs, the vapor pressure may cause internal
cracking or damage to the device. It can also result in external
steam jets from the package, and these may displace other
nearby components on the circuit board during the solder
process. A common industry reference for this is “popcorning”.
AVX solid tantalum and OxiCap® chips which are considered
MSL 1 are molded in plastic packages, and are packaged in
standard packaging, not including a moisture barrier unless
dry pack MSL 3 special option is used (special character V
in part number).
AVX solid tantalum and OxiCap® chips which are considered
MSL 3 are molded in plastic packages, and are distributed in
packaging including a moisture barrier.
AVX solid tantalum TCN PulseCap™ chips are considered
MSL4 and are moulded in plastic packages and are distributed
in packaging including a moisture barrier.
Product Safety Information Datasheet
Material Data and Handling
AVX solid tantalum TACmicrochips® (TAC, TPC) are considered MSL 1 and supplied in packaging with a moisture barrier. TLC series is considered MSL 3 and is distributed in
packaging including a moisture barrier.
7. Disposal
Incineration of epoxy coated capacitors will cause emission of
noxious fumes and metal cased capacitors may explode due to
build up of internal gas pressure. Disposal by any other means
normally involves no special hazards. Large quantities may have
salvage value.
8. Unsafe Use
Most failures are of a passive nature and do not represent a
safety hazard. A hazard may, however, arise if this failure causes a dangerous malfunction of the equipment in which the
capacitor is employed. Circuits should be designed to fail safe
under the normal modes of failure. The usual failure mode is an
increase in leakage current or short circuit. Other possible
modes are decrease of capacitance, increase in dissipation factor (and impedance) or an open-circuit. Operations outside the
ratings quoted in the datasheets represents unsafe use.
9. Handling
Careless handling of the cut terminal leads could result in scratches
and/or skin punctures. Hands should be washed after handling
solder coated terminals before eating or smoking, to avoid ingestion
of lead. Capacitors must be kept out of the reach of small children.
Care must be taken to discharge capacitors before handling as
capacitors may retain a residual charge even after equipment in
which they are being used has been switched off. Sparks from the
discharge could ignite a flammable vapor.

Environmental Information
AVX has always sought to minimize the environmental impact of its
manufacturing operations and of its capacitors supplied to customers
throughout the world. We have a policy of preventing and minimizing
waste streams during manufacture, and recycling materials wherever
possible. We actively avoid or minimize environmentally hazardous
materials in our production processes.
4. Fire Retardants
1. Material Content
5. Nickel Alloy
For customers wishing to assess the environmental impact of AVX’s
capacitors contained in waste electrical and electronic equipment,
the following information is provided:
Surface mount tantalum capacitors contain:
• Tantalum/Niobium and Tantalum/Niobium oxide
• Manganese dioxide
• Carbon/graphite
• Silver
• Tin/Tin-lead alloy plating
• Nickel-iron alloy or Copper alloy depending on design
(consult factory for details)
• Polymers including fluorinated polymers
• Epoxide resin encapsulant
The encapsulant is made fire retardant to UL 94 V-0 by the inclusion of inert mineral filler and fire retardants.
It is intended that all case sizes will be made with a high copper alloy
termination. Some case sizes are supplied now with this termination,
and other sizes may be available. Please contact AVX if you prefer this.
2. Packaging Material
The component packing tape is recyclable Polycarbonate and the
sealing tape is a laminate of halogen-free polymers. The reels are
recyclable polystyrene, and marked with the recycling symbol. The
reels are over-packed in recyclable fiber board boxes. None of the
packing contains heavy metals.
3. Lead (Pb)
Parts supplied today are electroplated over the terminal contact area
with 100% fused matte Tin (Sn). Parts with SnPb termination finish
are available upon request only. Contact AVX for availability of parts
with SnPb termination finish.
A combustible encapsulant free of antimony trioxide and organic
bromide compound are supplied today. AVX believes that the health
and safety benefits of using these materials to provide fire retardancy during the life of the product, far outweigh the possible risks to
the environment and human health.
6. Recycling
Surface mount Tantalum and OxiCap® capacitors have a very long
service life with no known wear-out mechanism, and a low failure
rate. However, parts contained in equipment which is of no further
use will have some residual value mainly because of the Tantalum
metal or niobium oxide contained. This can be recovered and
recycled by specialist companies. The silver and nickel or copper
alloy will also have some value. Please contact AVX if you require
assistance with the disposal of parts. Packaging can by recycled as
described above.
7. Disposal
Surface mount Tantalum and OxiCap® capacitors do not contain
any liquids and no part of the devices is normally soluble in water
at neutral pH values. Incineration will cause the emission of noxious
fumes and is not recommended except by specialists. Landfill may
be considered for disposal, bearing in mind the small lead content.
Under certain extreme physical conditions it is possible to generate
ignition of Tantalum, Niobium and Niobium oxide capacitors. These
physical conditions relate to high-speed impact and although not
considered to be a normal operating occurrence may occur as a
method of material(s) recovery. Therefore appropriate safeguards
procedures and methodologies need to be adopted to eliminate
any risks of material ignition.
For further information, please contact your local AVX sales office
or representative.
