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 sili-
cone coating provides excellent protection & solvent resistance. Tin (or SnPb)
coated copper/copperweld leads ensure proper solderabilty and extended
shelf life. Marked with resis.value & tol. as minimum (custom marking avail).
World’s widest range! 0.005Ω ~2MΩ, ±0.005% ~10%, 0.5W ~50W.
Low cost, available from stock & exclusive SWIFTTM delivery program.
OPTIONS
Option X: Low Inductance
Option P: Increased Pulse Capability
Option F: Flameproof Coating UL94V-0
Option ER: 100-Hour Burn-In
Option B: Increased Power
PULSE CAPABILITY: Excellent pulse ability is inherent with the all-welded
wirewound construction, but can be enhanced by a factor of 50% or more
via special Option P processing (up to 500 joules). Pulse capability is highly
dependent on pulse duration, repetition rate & resis. value, consult factory.
Radial leads (opt.R), low thermal emf (opt.E), matched sets, custom
marking, cut & form, 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 (per MIL-R-39007). Specialty

≤1%, & is dependent on resis, options, etc. Consult factory for Char.V & tol >1% 5 Military p/n’s are given for reference only & do not imply qualification or exact interchangeability 6 Increased range avail 7 Resis value measured
at 3/8”±1/16 from each end of body 8 Heavier lead gauge option is recommended on low values to enable lower leadwire resis., increased current, & improved TC 9 Lead length applies to bulk packaged units (taped parts
generally have shorter leads, refer to taping spec.) 10 Series 100 has dual power rating depending on temp.rise & stability requirements; derate 50% to ensure high reliability & operational life stability
