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.

ꢀ World’s widest range of axial lead WW resistors! 0.005Ω to 2MΩ,
tolerances to ±0.005%, 1/2W to 50W, numerous design options
ꢀ Low cost!Available on exclusive SWIFTTM delivery program
OPTIONS
ꢀ Option X: Low Inductance
ꢀOption P: Increased Pulse Capability
ꢀOption F: Flameproof Coating
ꢀOption ER: 100-Hour Burn-In
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).
ꢀ Option B: Increased Power
ꢀ 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!
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 (perMIL-R-39007). Specialty
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

constructions are available for even lower
