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.
