MSM45 series
Specially developed for
automatic mounting these
modern 18:12 inductors are
offered in two series. The A
type ~ a standard part which
is available from Farnell
Electronic Components, and
the newer MSM45 types ~ a
lower cost version with
extended temperature range
and value limits. The MSM45
Series are available via
distribution from the Arrow
