PWLL & PWH SERIES

5W TO 50 WATT POWER RESISTORS
CERAMIC ENCASED, RADIAL LEADS
RoHS
PWLL & PWH SERIES
Term.”W”
is Pb-free
and RoHS
compliant;
“Q” is Sn-Pb
RESISTORSCAPACITORSCOILSDELAY LINES
 Low cost, fireproof construction
 0.1Ω to 150KΩ, ±5% is standard (0.5% to 10% avail.)
PWLL and PWH resistors are designed for general purpose and
semi-precision power applications. The ceramic construction is
 Option X: Non-Inductive
fireproof and resistant to moisture & solvents. The internal element is
 Option P: Increased pulse capability
wirewound on lower values, power film on higher values
 Option G: 1/4x.032” male fast-on terminals (PWH&PWHM15-50) (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).
