type HS series
The HS series is the `flagship'
product of the Meggitt
Electronics power product
range. A major business, in this
one product, Meggitt are the
leading European supplier of
standard and custom designed
Aluminium Clad Resistors, for
general purpose use, power
supplies, generation and the
traction industries. A particular
Meggitt strength in this area, is
customised HS resistors where
high quantities are not required.

Certain styles are approved to
CECC specification, others are
designed to conform to MIL, or
customer specifications. We will
be happy to advise on the use of
resistors for pulse applications,
and to supply further
information for high voltage
use, low inductive and low
ohmic value components,
alternative mountings and
terminations. A full range of
HS resistors, is available from
Meggitt distributors.
