OPERATIONAL DATA
RELIABILITY
Operational Lifetime
Please see separate BHC application
notes TD003 for calculating operational
life expectancy under customer specific
conditions.
The failure rate is derived from our periodic
test results. The failure rate (λ ) is therefore
R
only given at test temperature for life tests.
An estimation is also given at 40°C. The
expected failure rate for this capacitor range
is based on our periodic test results for
capacitors with structural similarity. Failure
rate is frequently quoted in FIT (Failures In
Time) where 1 FIT = 1 x 10^-9 failures per hour.
Failure rates include both catastrophic and
parametric failures

MECHANICAL DATA
Mounting position
The capacitor can be mounted in any
position so long as the safety vent can
operate. It is possible for some electrolyte
to be expelled. As this is a conducting liquid,
suitable precautions should be instigated
by the system designer to avoid secondary
short circuits.
The capacitors are designed to be mounted
in free air and are not suitable for submersion
in liquid.
Vibration
10Hz to 55Hz at 0.75mm or 10g for 3x2hrs
duration. Except 220mm long cans 10Hz
to 55Hz at 0.35mm or 5g for 3x0.5hrs
duration.
Insulating resistance
> 100 Mohms at 100V d.c., across insulating
sleeve.
Voltage Proof
> 2500V d.c., across insulating sleeve.
Safety vent
A safety vent for over pressure is featured on
terminal deck. This is in the form of a rubber
plug designed to relieve build up of internal
pressure due to over stress or catastrophic
failure.
