Damping, Commutating
B 25 838
High dielectric strength
High peak-current capability
For damping and commutating in
the upper frequency range
Construction
● Self-healing
● Plastic dielectric
● Oil-impregnated tubular windings (no PCB)
● Metal-sprayed end faces ensure reliable contacting
● Cylindrical aluminum case
● Ceramic lead-throughs
● Mounting bolts M8 or M12
Terminals
● Screw terminals M10
● Tab connectors 6,3 mm
● Dual tab connectors 6,3 mm
Mounting parts
● If the vibration stress is ≤ 5 g and the capacitors are ≤ 60 mm in diameter
and ≤ 160 mm in height the bolt is used for mounting.
● In case of a vibration stress > 5 g as well as for larger-sized capacitors refer
to chapter “Mounting parts”.
Grounding
● Mounting bolt for grounding in accordance with VDE 0100
● Grounding identification in accordance with DIN 40 011
Overpressure disconnector (mechanical)
When the overpressure disconnector responds,
the capacitor extends by up to 8 mm.
So leave sufficient space above the terminals
when mounting the capacitor.
Individual data sheets
Individual capacitors of this series are specified in detail
(incl. thermal data) on pages 192 … 205.
Upon request, these data sheets are available for each capacitor type.
