Mounting recommendation

Packing

To minimize or avoid shock and/or vibration stresses to terminating wires and solder connections we recommend to fix voluminous resin-potted MP capacitors as from e.g. PCM 22.5mm in an appropriate way since for constructional reasons they do not sit tight on the board.

Available taped and reeled up to and including PCM 22.5mm

Detailed taping information:

Example for ordering / Part number:

* If safety-approved EMI suppression capacitors are operated with a DC voltage being above the specified AC voltage rating the given approvals are no longer valid (DIN EN 60384-14).

Furthermore the permissible pulse rise time du/dt (Fmax.) will be subject to a reduction according to

Fmax. = Fr x x UAC / UDC

if the DC operating voltage UDC is higher than x UAC
