PWLL and PWH resistors are designed for general purpose and
semi-precision power applications. The ceramic construction is
fireproof and resistant to moisture & solvents. The internal element
is wirewound on lower values, power film on higher values
(depending on options, e.g. opt. P parts are always WW). If a
specific construction is preferred, specify opt.’WW’ for wirewound,
opt.’M’ for power film (not available in all values).
