Radial leads (opt.R), low thermal emf (opt.E), matched sets, special
marking, cut &formed leads, hi-rel screening, non-standard values,
high voltage, etc. Customized components are RCD’s speciality!
DERATING
(derate W/V/A ratings when ambient temp. exceeds 25°C):
Char. U is the max. power for ±0.5% typ. load life stability & 275°C
hotspot, Char. V is max. power for ±3% stability & 350°C hotspot
% RATED POWER
Series 100 resistors offer exceptional performance at an economical
cost. Superior stability results from welded construction and windings of
premium grade resistance wire on thermally conductive ceramic cores.
Hi-temp coating provides excellent environmental protection and solvent
resistance. Tin (or SnPb) coated copper or copperweld leads offer
excellent solderabilty and extended shelf life.
PULSE CAPABILITY:
Excellent pulse capability results from wirewound
construction. The pulse/overload capability can often be economically
enhanced by a factor of 50% or more via special Option P processing.
Pulse capability is highly dependent on size and resistance value, consult
factory (available up to 500 joules).
INDUCTANCE:
small sizes have inductance of 1- 50uH typ. Larger sizes
and higher values typically have greater levels. For non-inductive design,
specify Opt. X. The max. series inductance for Opt.X resistors at 0.5MHz
is listed in table (per MIL-R-39007). Specialty
