Mounting Recommendation
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 22.5 mm in an
appropriate way since for constructional
reasons they do not sit tight on the
board.
Packing
Available taped and reeled up to and
including PCM 22.5 mm.
