Product safety
The table below summarizes the safety instructions that must be observed without fail. A detailed
description can be found in the relevant sections of Data Book 2007 – Aluminum Electrolytic
Capacitors, chapter "General technical information".
Topic Safety Information Reference
Chapter ‘General technical
information”
Polarity Make sure that polar capacitors are
connected with the right polarity.
1
“Basic construction of aluminum
electrolytic capacitors”
Reverse voltage Voltages polarity classes should be
prevented by connecting a diode.
3.1.6
“reverse voltage”
Upper category temperature Do not exceed the upper category
temperature.
7.2
“Maximum permissible operating
temperature”
Maintenance Make periodic inspections of the
capacitors.
Before the inspection, make sure
that the power supply is turned off
and carefully discharge the
electricity of the capacitors.
Do not apply any mechanical stress
to the capacitor terminals.

“Maintenance”
Mounting position of screw terminal
capacitors
Do not mount the capacitor with the
terminals (safety vent) upside
down.
11.1.
“Mounting positions of capacitors
with screw terminals”
Mounting of single-ended
capacitors
The internal structure of single-
ended capacitors might be
damaged if excessive force is
applied to the lead wires.
Avoid any compressive, tensile or
flexural stress.
Do not move the capacitor after
soldering to PC board.
11.4
“Mounting considerations for
single-ended capacitors”
Robustness of terminals The following maximum tightening
torques must not be exceeded
when connecting screw terminals:
M5: 2 Nm
M6: 2.5 Nm
11.3
“Mounting torques”
Soldering Do not exceed the specified time or
temperature limits during soldering.
