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.

“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

“Mounting torques”

Soldering

Do not exceed the specified time or

temperature limits during soldering.
