Polarity

Make sure that polar capacitors are connected

with the right polarity.

"Basic construction of

aluminum electrolytic

capacitors"

Reverse voltage

Voltages of opposite polarity should be prevented

by connecting a diode.

Mounting

position of screw-

terminal capacitors

Screw terminal capacitors must not be mounted

with terminals facing down unless otherwise

specified.

"Mounting positions of

capacitors with screw

terminals"

Robustness of

terminals

The following maximum tightening torques must

not be exceeded when connecting screw

terminals:

M5: 2.5 Nm

M6: 4.0 Nm

11.3

"Mounting torques"

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.

Do not pick up the PC board by the soldered

capacitor.

Do not insert the capacitor on the PC board with a

hole space different to the lead space specified.

considerations for

single-ended capacitors"

Soldering

Do not exceed the specified time or temperature

limits during soldering.

11.5

"Soldering"

Soldering,

cleaning agents

Do not allow halogenated hydrocarbons to come

into contact with aluminum electrolytic capacitors.

11.6

"Cleaning agents"

Upper category

temperature

Do not exceed the upper category temperature.

"Maximum permissible

operating temperature"

Passive

flammability

Avoid external energy, e.g. fire.
