Cooling space for capacitors

Make sure that sufficient cooling space is provided:

• A minimum distance of 20 mm between the capacitors is necessary to maintain sufficient

cooling.

• Keep at least 20 mm space above the capacitor and do not attach any mounting components

at the crimp or on top. This gap will allow a longitudinal extension of the can in order to

ensure that the over-pressure disconnector can fully extend.

Note

The pictures depicted above are for illustration purposes only. Actual sample will be as per MLFB

type.

Using reactors: cooling space for cables

If reactors are used in an application, note that they operate at a much higher temperature. The

distance between the reactor and capacitor must be large enough so that no reactor heat is

conducted via the connection cable to the capacitor, or that heat radiation from the reactor to

the capacitor causes overheating.
