Film capacitors – Power electronic capacitors
MKP PEC DC
B2562*
Preliminary data
Cautions and warnings
° In case of dents of more than 1 mm depth or any other mechanical damage, capacitors must not be used at
all.
° Check tightness of the connections/terminals periodically.
° The energy stored in capacitors may be lethal. To prevent any chance of shock, discharge and short-circuit
the capacitor before handling.
° Failure to follow cautions may result, worst case, in premature failures, bursting and fire.
° EPCOS AG is not responsible for any kind of possible damages to persons or things due to improper
installation and application of capacitors for power electronics.
Safety
° Electrical or mechanical misapplication of capacitors may be hazardous. Personal injury or property damage
may result from bursting of the capacitor or from expulsion of oil or melted material due to mechanical
disruption of the capacitor.
° Ensure good, effective grounding for capacitor enclosures.
° Observe appropriate safety precautions during operation (self-recharging phenomena and the high energy
contained in capacitors).
° Handle capacitors carefully, because they may still be charged even after disconnection.
° The terminals of capacitors, connected bus bars and cables as well as other devices may also be energized.
° Follow good engineering practice.
Thermal load
After installation of the capacitor it is necessary to verify that maximum hot-spot temperature is not exceeded at
extreme service conditions.
Mechanical protection
The capacitor has to be installed in a way that mechanical damages and dents in the aluminum can are
avoided.
Storage and operating conditions
Do not use or store capacitors in corrosive atmosphere, especially where chloride gas, sulfide gas, acid, alkali,
salt or the like are present. In dusty environments regular maintenance and cleaning especially of the terminals
is required to avoid conductive path between phases and/or phases and ground.
The maximum storage temperature is 85 °C.
Service life expectancy
Electrical components do not have an unlimited service life expectancy; this applies to self-healing
capacitors, too. The maximum service life expectancy may vary depending on the application the
capacitor is used in.
